Is a Vacuum Sealer Worth It? The NZ Food Waste Test Before You Buy
A vacuum sealer can be worth it when you already freeze food, batch cook, buy larger packs or often lose suitable food to poor storage. Here is how to judge the value in your own NZ kitchen, without fake payback maths.
There is a particular kind of kitchen frustration that starts with good intentions. You buy enough for several meals, put the leftovers away, freeze a few portions, open a packet for later, then discover part of it weeks afterwards. The leftovers are forgotten. The frozen food is dry around the edges. The opened food has lost the quality you wanted. You paid for the food once, then you pay again when you replace what went into the bin.
So, is a vacuum sealer worth it? For many households, yes, especially if you already freeze food, batch cook, buy larger packs or regularly lose suitable food because air and poor storage get to it first. It is much harder to justify if you would only use it occasionally and it is likely to spend most of its life at the back of a cupboard.
That distinction matters more than any headline promise about savings. A vacuum sealer creates value when it changes what actually happens to food in your home.
Where the money disappears before the bin lid closes
Food waste rarely feels expensive in the moment. Half a container of cooked chicken here, a few portions of mince there, an opened block of cheese that dries out, or a family-size grocery pack that was cheaper per kilo but too much to use quickly. Each loss looks small on its own.
Across New Zealand, Love Food Hate Waste reports that the average household throws away around $1,364 worth of food a year, based on the 2025 Rabobank-KiwiHarvest Food Waste survey. That national figure is useful context, not a promise about what any one household will save. The useful question is simpler: how much of your own discarded food was still suitable when you bought or cooked it, but lost quality before you got back to it?
Freezers are a common place for that value to disappear. A family pack may go straight into the freezer in one bulky package, then be awkward to thaw for a smaller meal. A batch-cooked dinner may be stored in a container with too much air around it. A forgotten bag can develop freezer burn, which is a quality problem caused by air reaching the food surface.
The fridge has its own version. Leftovers get pushed behind newer food. Opened foods are covered loosely. A sauce, cheese, deli item or prepared meal may still have had another use in it, but its storage did not make that next use easy.
This is where our VacSy food preservation collection makes the most sense. The goal is not to seal everything in sight. It is to give food you already intend to eat a better chance of staying organised, protected from excess air exposure and ready for the way you plan to use it.
What vacuum storage can actually change
Vacuum storage removes air from compatible packaging or containers. Reducing that air exposure can help protect food quality and slow some spoilage processes. In the freezer, good airtight packaging also helps reduce the air contact that contributes to freezer burn.
For larger grocery purchases, portioning is often the practical win. Instead of freezing a large pack as one block, you can divide suitable food into amounts that match future meals. Our Green VacSy Sealing Unit has an automatic vacuum packing function for compatible bags, so it suits households that regularly want flat, sealed freezer portions.
That can make the freezer easier to use as well as easier to fill. Smaller sealed portions can be labelled, stacked and chosen without thawing more food than you need. The value comes from making the next meal easier to reach, not simply from owning another appliance.
Leftovers and opened foods often need a different approach. If you want to open, use and close the same food again, a rigid container or suitable lid can be more convenient than making a new bag each time. Our portable VacSy Vacuum Pump is a compact option for compatible container-based storage, while the VacSy Universal Lid 8 to 16 cm can work with suitable jars, glasses, cups and other compatible containers.
If you are deciding whether your kitchen is mainly a bags kitchen, a containers kitchen or a mix of both, our Vacuum Sealer NZ Buying Guide: Bags, Containers or Both? goes deeper into that choice.
What a vacuum sealer cannot fix
A vacuum sealer is useful storage equipment, not a rescue plan for every food problem. If you routinely buy more food than your household can realistically eat, better packaging alone will not fix the overbuying. It works best when there is already a plan for the extra portions.
It also does not make unsafe food safe. Vacuum packaging can help preserve quality and slow some spoilage processes, but it does not replace refrigeration, freezing, prompt cooling, clean preparation, correct storage temperatures or use-by guidance. Some foods are not suitable for every vacuum-storage method, so food type and storage conditions still matter.
The same is true for leftovers. Food needs to be cooled and stored safely first. Removing air from a container does not reset the clock on food that has been left out too long or handled poorly.
And there is one very ordinary downside worth taking seriously: an appliance only creates value if it is easy enough to use. If the sealer is buried behind rarely used kitchen gear, or if you dislike the extra step of portioning and sealing, it may be poor value even if the technology itself works well.
How to judge value without pretending every wasted dollar can be recovered
We would start with your existing food habits, not a made-up payback calculation. Think about the food you already freeze, the number of meals you cook in batches, how often you buy larger packs, and how frequently you find food that has dried out, gone stale or been forgotten before you could use it.
If those things happen often, vacuum storage has repeated opportunities to be useful. A household freezing meat, fish, prepared meals or baking every week may use a bag sealer regularly. Someone who cooks extra portions for work lunches may get more value from containers. A household that buys little, freezes almost nothing and rarely has leftovers may simply not have enough storage problems for a vacuum system to solve.
It is also fair to count the practical costs. Bag sealing means ongoing consumables, so replacement rolls should be part of the picture. Our VacSy Bag Rolls are available for the sealing unit, and you will need cupboard or drawer space for them. If you want a detailed look at bag construction and selection, see our Vacuum Pack Sealer Bags NZ guide.
Counter or cupboard space matters too. The best fit is the system you will actually reach for when you split a grocery pack, put dinner away or organise the freezer. Frequency of use is a much better value signal than trying to turn every discarded dollar into theoretical savings.
How VacSy gives us more than one way to make food storage useful
One reason we like VacSy is that different food losses call for different storage formats. The Green VacSy Sealing Unit gives you automatic vacuum packing for compatible bags, which is useful when you want to portion food for the freezer and seal it flat. Its supplied adaptor also lets the unit work with compatible VacSy containers, universal lids and bottle caps.
That means the same bench unit can cover more than freezer bags. A large grocery purchase can be split into meal-size bag portions, while food you expect to open again can go into a compatible container or under a compatible lid. The built-in liquid sensor helps protect the unit when vacuuming higher-moisture foods, and an integrated overheating sensor is another useful safeguard during operation.
For households whose main problem is not freezer bags at all, the portable VacSy Vacuum Pump offers a more container-focused option. It can be used with compatible VacSy containers and suitable compatible lids, making it a practical choice for leftovers, opened foods and storage you want to access repeatedly.
That flexibility is important because food waste does not happen in one standard way. One kitchen loses value through freezer-damaged bulk purchases. Another keeps forgetting half-used foods in the fridge. Another batch cooks every Sunday and wants portions ready for the week. We would rather match the storage format to the food than push every job into the same bag.
EXPLORE THE VACSY SEALING UNIT
So, is a vacuum sealer worth it in your kitchen?
If you freeze food most weeks, batch cook, buy family-size packs, prepare meals ahead or regularly throw out suitable food that has dried out or lost quality in storage, we believe vacuum storage is well worth considering. Those habits give the system repeated jobs to do, which is where its value becomes easier to see.
If you rarely freeze food, usually cook exactly what you eat, have very few leftovers and know you will not bother sealing or pumping containers, you may get less value. In that case, simpler covered containers and better meal planning may be enough.
The useful test is not whether vacuum sealers can save money in theory. It is whether you can already name the foods in your own kitchen that would be portioned, sealed, stored and eaten differently if the right VacSy format was within reach.
Common questions about whether a vacuum sealer is worth it
Is a vacuum sealer worth it for the average NZ household?
A vacuum sealer can be worth it for an NZ household that regularly freezes food, batch cooks, buys larger packs or stores leftovers. It is less likely to offer good value when it would only be used occasionally.
Does a vacuum sealer actually save money?
It can help reduce avoidable food waste when better storage means suitable food is eaten instead of discarded, but savings depend on what you buy, how you store it and how often you use the system. We would not promise a fixed saving or payback period.
Is a vacuum sealer worth it if I do not buy in bulk?
It can be. Bulk buying is only one reason to use vacuum storage. Leftovers, batch-cooked meals, opened foods and freezer portions can all create regular uses even when you shop in smaller amounts.
Can vacuum sealing reduce food waste?
Yes, it can help reduce some avoidable food waste by limiting air exposure, improving portioning and making stored food easier to organise and use. It cannot fix overbuying, unsafe handling or food that was already unsuitable before sealing.
Does vacuum sealing help prevent freezer burn?
Vacuum sealing can help reduce the air contact that causes freezer burn when suitable food is packaged correctly for freezing. Freezer burn affects food quality rather than making the food unsafe by itself.
What are the downsides of owning a vacuum sealer?
You need space for the equipment, time to portion and seal food, and ongoing bags or rolls if you use bag sealing. It can also be poor value if you do not use it often enough to change how you store food.
Does vacuum sealing replace refrigeration or freezing?
No. Vacuum sealing does not replace refrigeration, freezing, prompt cooling, clean preparation, correct storage temperatures or use-by guidance. Vacuum-packed food still needs the storage conditions appropriate for that food.
Next steps
Before you buy, notice what you are actually throwing away or finding damaged in the freezer. If the same problems keep appearing, choose the VacSy format that fits those foods: sealed bags for freezer portions, compatible containers and lids for food you reopen, or a combination when your kitchen genuinely uses both.

Vacuum Sealer NZ Buying Guide: Bags, Containers or Both?

You have a tray of chicken to portion for the freezer, last night’s pasta for tomorrow’s lunch, a punnet of berries that bruises easily, half a jar of pasta sauce and a pot of soup still to put away. The buying decision quickly becomes muddled. Do you need a bag sealer, vacuum containers, special lids, or a system that can handle all three?
The most useful question is not which vacuum sealer machine NZ households should buy first. It is which storage jobs happen most often in your kitchen.
Direct answer: Choose bags for compact freezer portions, food that will stay sealed until needed and longer-term organisation. Choose containers for delicate foods, liquids and food you open repeatedly. Choose a combined system when your household regularly uses both fridge containers and space-efficient freezer portions.
Start with the food, not the machine
A good vacuum sealer NZ decision begins with your normal routine. Work through the questions below before comparing hardware.
How long are you planning to store it? Food being portioned for later freezer use often suits a sealed bag. Food being kept for tomorrow’s lunch or opened over several days often suits a container.
Where will it live? Bags can use freezer space efficiently because they conform to the food. Containers can be easier to stack and see in the fridge or pantry, but they keep their full footprint even when partly filled.
How often will you reopen it? A package opened once may suit a bag. Cheese, dry goods, leftovers and snacks that are opened repeatedly may be easier in a container or under a compatible vacuum lid.
Can it be crushed? Berries, leafy greens, soft baking and composed lunches usually benefit from rigid protection. Meat portions, firm vegetables and flat meal components may be well suited to bags.
Is it dry, moist or liquid? Dry and firm foods are usually straightforward. Liquids and very moist foods need extra care, prompt cooling and a format that keeps liquid away from the sealing mechanism. A rigid container is often the simpler route.
How much space do you have? A bag-based system trades a roll of consumable material for compact packs. A container-based system trades reusable rigid storage for more cupboard, fridge and drying-rack space.
This storage-job rule keeps a food vacuum sealer NZ purchase grounded in what you actually cook, portion and reopen.
Bags vs containers: the practical decision matrix
Decision factor
Vacuum sealer bags
Vacuum containers
Best uses
Portioned meat and fish, firm freezer portions, batch-cooked components, bulk purchases and food stored until needed
Leftovers, delicate produce, liquids, meal-prep lunches, dry goods and foods opened repeatedly
Main limitations
Opening usually breaks the seal, liquids need careful handling and each new pack uses bag material
Rigid footprint, higher space demand and compatibility depends on the lid, valve and pump or adaptor
Crushing risk
Higher for berries, greens and soft foods unless the process is carefully controlled
Lower because rigid walls protect the contents
Liquid handling
Possible only with suitable preparation and equipment instructions; liquid must not interfere with the seal
Usually the more convenient pathway for soups, sauces and moist leftovers
Reopening convenience
Best when the pack will be opened once
Well suited to repeated opening, serving and resealing
Freezer efficiency
Often excellent because portions can be flattened and arranged closely
Uses a fixed volume and may leave unused air space around the food
Stackability
Flat packs can stack well once frozen, though loose or irregular packs may slide
Predictable shapes can stack neatly when sizes are planned together
Cleaning
Usually less washing after use, but bag reuse depends on the manufacturer’s instructions and safe cleaning
Requires washing and thorough drying of the container, lid, seal and valve
Ongoing consumables
Requires compatible bags or rolls over time
Usually fewer disposable consumables, but seals, valves or lids may eventually need care or replacement
Required hardware
A heat-sealing vacuum sealer and compatible bag material
A compatible pump or a sealing unit with the correct adaptor, plus matching containers or lids
System compatibility
Bag texture, width and sealing specifications must match the machine
The pump, hose or adaptor, valve and lid must be designed to work together
Route common foods to the right format
The table below is a starting point, not a shelf-life promise. Food condition, preparation, temperature and product instructions still matter.
Food
Likely starting format
Why it may fit
Practical note
Meat portions
Bags
Compact, clearly portioned freezer packs
Label and date each pack, keep raw food separate and freeze when required
Fish
Bags or rigid container
Bags suit firm freezer portions; a container may better protect delicate fillets
Keep cold, work cleanly and follow food-specific storage guidance
Batch-cooked meals
Bags for freezer portions; containers for fridge meals
The right choice depends on whether the meal will be frozen flat or reopened soon
Cool promptly before packaging and keep liquids away from a bag’s sealing area
Leftovers
Containers
Easy to see, serve, reopen and reseal
Use a size that leaves practical headroom without wasting fridge space
Berries
Containers
Rigid walls reduce crushing
Store only sound produce and avoid trapping excess surface moisture
Salad greens
Containers
Protects leaves from compression and makes repeated access easier
Clean and dry according to your normal safe produce routine
Cheese
Container for repeated use; bag for an unopened portion
Choose according to how often you will cut or serve it
Follow the cheese maker’s storage guidance and watch for spoilage
Soups and sauces
Containers
Easier liquid control and repeated serving
Cool promptly and do not allow liquid into a pump or sealing channel
Pasta, cereal and dry goods
Containers
Convenient for scooping, closing and reopening
Choose a container shape that fits the pantry shelf and utensil you use
Opened jars
Compatible universal lid
Keeps the food in its original jar while adding a vacuum pathway
Confirm jar diameter, lid fit and valve compatibility before use
Meal-prep lunches
Containers
Protects presentation and makes transport and reheating routines simpler
Check the container instructions before microwaving or carrying liquids
Three ways to start
1. Freezer Batch Cook
Who it suits: Households portioning meat, fish, bulk purchases or cooked meal components for later use.
What it solves: It turns a large shop or cooking session into compact, labelled portions that can be arranged efficiently in the freezer.
What to buy first: Start with a compatible sealing unit and enough bag material for your usual portion sizes. The VacSy bag roll set includes two roll widths so custom lengths can be cut for different jobs.
What may be added later: Add containers when you notice that moist leftovers, delicate food or frequently reopened items are awkward in bags.
Main trade-off: You gain compact freezer storage, but compatible bag material becomes an ongoing consumable and the machine needs a practical setup area.
2. Everyday Fridge Keeper
Who it suits: Households mainly storing leftovers, berries, greens, cheese, dry goods, sauces or foods opened repeatedly.
What it solves: It creates an easy open, serve and reseal routine without cutting open a new bag each time.
What to buy first: Begin with a compatible pump and a small group of container sizes that match your fridge shelves and portions. Browse the current VacSy glass container range by shape and capacity before deciding.
What may be added later: Add a compatible universal lid for suitable jars, glasses or cups, or add a bag-sealing pathway when freezer portions become more important.
Main trade-off: Containers are reusable and convenient, but they take fixed cupboard, fridge and drying space.
3. Whole Kitchen System
Who it suits: Mixed households that freeze portions, refrigerate leftovers, organise dry goods and regularly reopen jars or containers.
What it solves: It avoids forcing one format onto every food. Bags handle compact storage jobs while containers and lids handle repeated-access jobs.
What to buy first: Start with the hardware pathway you will use most this month, then add the second format deliberately rather than buying every accessory at once.
What may be added later: Expand with compatible containers, lids, bottle caps or additional bag rolls after you have measured actual use.
Main trade-off: A combined system is versatile, but it requires more storage planning and careful compatibility checks.
EXPLORE THE VACSY SEALING UNIT
The VacSy Two-Path System: One Sealing Unit, Two Ways to Store
The VacSy sealing unit provides the bag pathway by removing air and heat-sealing compatible bags. Its supplied adaptor also turns the unit into a vacuum source for compatible VacSy containers, universal lids and bottle caps. That makes it a practical starting point for a household that regularly freezes portions but still wants the option to add rigid storage.
The alternative starting point is the portable VacSy Vacuum Pump. It is intended for compatible VacSy containers, suitable Zepter cookware and compatible commercial containers or lids. This route may be simpler for a household whose main jobs are leftovers, dry goods, meal-prep lunches and food that is opened repeatedly.
Regular freezer portions: Begin with the sealing unit, compatible bags and a clear labelling routine.
Mainly fridge containers and lids: Begin with the portable pump and the container sizes you will actually use.
Mixed fridge and freezer storage: Use the sealing unit for bags and its adaptor for compatible containers, or combine a bench sealer with a portable pump when separate work zones make sense.
A compatible VacSy universal lid may also help with suitable opened jars and containers, while the VacSy system overview shows how the wider range fits together. Compatibility should be checked before purchase because not every bag, lid, valve or container is interchangeable.
Plan for what the household will keep buying and storing
Bag-roll widths and custom lengths
Rolls let you cut a bag length around the portion rather than relying on one fixed size. Before buying, compare the available width with the widest foods you commonly pack, then allow enough extra length for the seal and any future trimming. A wider roll can be useful for bulky portions, while a narrower roll may reduce unused material for smaller packs.
Ongoing bag use
Estimate bags by routine, not by aspiration. A household sealing five freezer portions each week will use material differently from one sealing only monthly bulk purchases. Include failed seals, extra length and any manufacturer limits on reuse in your budget.
Container footprint
Measure the shelf height, depth and width of your fridge and pantry. Choose a small family of useful sizes rather than a mismatched collection. Containers that nest for storage or stack predictably when full can make the system easier to live with.
Cleaning and drying
Vacuum storage relies on clean sealing surfaces. Wash parts according to the manufacturer’s directions, check seals and valves for trapped food, and let everything dry fully before reassembly. A container that is convenient to fill but difficult to clean may not survive the daily routine.
Labelling and dating
Vacuum packs can look tidy while becoming hard to identify. Label the food, preparation or packing date, and any use-by instruction you need to follow. For freezer packs, write before the bag becomes cold or wet so the label remains readable.
Accessory compatibility
Check the whole connection chain: machine or pump, hose or adaptor, valve, lid and container. For bags, check width and material compatibility with the heat sealer. For containers, check valve design, lid size and whether the product is intended for the storage temperature or reheating method you plan to use.
Bench or cupboard?
A vacuum sealer for home use only works when it is accessible enough to become part of the routine. Decide whether the sealing unit will stay on the bench, live in a nearby cupboard or be brought out for batch sessions. Keep the pump, adaptor and labels together so a two-minute storage job does not become a search for missing parts.
Food-safety guardrails for vacuum food storage NZ households
Vacuum packaging may help preserve food quality and extend the useful storage period of some foods, but it does not make unsafe food safe. Removing air can slow some spoilage processes while creating conditions in which certain hazards may not produce obvious warning signs. New Zealand Food Safety advises that many fresh and minimally processed vacuum-packed foods still require refrigeration and that storage instructions and use-by dates must be followed.
Vacuum sealing does not replace:
Appropriate refrigeration
Freezing when required
Prompt cooling
Clean preparation
Date labelling
Food-specific storage guidance
Normal food-safety judgement
Use food-grade packaging intended for the food and conditions of use. Only reuse packaging when it is designed for reuse and can be properly cleaned and sanitised. Discard damaged bags, worn seals or containers that no longer close as intended.
Your five-point purchase checklist
What food will I store most often?
Will it mainly go into the fridge, freezer or pantry?
Will I open it once or repeatedly?
Do I need bags, containers or both?
What consumables and compatible accessories will I need?
Write down the answers using a normal week of food, not an idealised future routine. The pattern usually makes the first purchase obvious.
Frequently asked questions
Are vacuum sealer bags or containers better?
Neither is better for every job. Bags usually suit compact freezer portions and food stored until needed. Containers usually suit delicate foods, liquids and food opened repeatedly. Many households benefit from using both.
Can a vacuum sealer be used with containers?
Yes, when the machine or pump has the correct adaptor and the container has a compatible vacuum valve or lid. Check the appliance, hose, adaptor and container compatibility before buying.
Do I need a sealing machine if I only want vacuum containers?
Not necessarily. A compatible portable vacuum pump may be the simpler starting point when your routine is mainly container storage, compatible cookware or vacuum lids rather than heat-sealed bags.
Which foods are better stored in vacuum containers than bags?
Containers are often the more practical choice for berries, salad greens, leftovers, meal-prep lunches, liquids, delicate foods and items you reopen frequently because the rigid walls reduce crushing and the lid is easy to open and reseal.
Can I vacuum seal liquids or delicate foods?
Yes, but the format matters. Rigid containers are usually easier for liquids and crushable foods. For bag sealing, follow the machine instructions, cool food promptly, keep liquid away from the sealing area and use a method suitable for moist food.
Are vacuum sealer bags reusable?
Only reuse a bag when its manufacturer says it is designed for reuse and it can be properly cleaned, sanitised and dried. Do not reuse damaged bags or bags that cannot be safely cleaned. Treat bag rolls as an ongoing consumable unless the product instructions confirm otherwise.
What should I look for when buying a vacuum sealer in NZ?
Start with the food you store, whether it goes into the fridge, freezer or pantry, how often you reopen it, your available space and the compatible bags, containers and accessories. Then compare hardware, cleaning, storage and ongoing consumable needs.
Does vacuum sealing replace refrigeration or freezing?
No. Vacuum sealing does not make unsafe food safe and does not replace refrigeration, freezing, prompt cooling, clean preparation, date labelling or food-specific storage guidance.

Next steps: choose the pathway your routine will use
For a freezer-first household, begin with bags and a sealing unit. For a fridge-first household, begin with a pump and well-chosen containers. For a mixed kitchen, use both formats for the jobs they handle best. The strongest purchase is not the system with the most parts. It is the one that fits your food, space and reopening habits closely enough to use every week.

Vacuum Pack Sealer Bags: Complete Guide for NZ Kitchens
A complete NZ guide to vacuum pack sealer bags, including types, materials, and how to choose the right option for food storage and freshness.
Quick answer: Vacuum pack sealer bags are specially designed airtight bags that remove air to extend food freshness, reduce freezer burn, and improve storage efficiency. Choosing the right type depends on your food, storage method, and sealing system.
What are vacuum pack sealer bags?
Vacuum pack sealer bags are durable plastic bags used with vacuum sealing machines to remove air and tightly seal food. By limiting oxygen exposure, they help slow spoilage and maintain food quality for longer.
In New Zealand kitchens, we see these used for meal prep, bulk storage, sous vide cooking, and reducing food waste.
Why use vacuum sealing bags?
Extend shelf life of fresh and frozen food
Prevent freezer burn
Save space in fridges and freezers
Keep flavours and nutrients better preserved
Support bulk buying and meal prep
If you are already investing in quality cookware, understanding storage is just as important. For example, pairing good storage with stainless steel cookware helps maintain food quality from prep to plate.
Types of vacuum pack sealer bags
Embossed vacuum bags
These have a textured surface that allows air to be removed efficiently. They are the most common option for external vacuum sealers.
Chamber vacuum bags
Smooth and typically cheaper per unit, these are designed for chamber vacuum machines. They are popular for high-volume use.
Reusable vacuum bags
Reusable options are growing in popularity for sustainability-focused households. They are best for dry foods or short-term storage.
Freezer-specific vacuum bags
Thicker materials help prevent freezer burn and are ideal for long-term storage of meat, seafood, and prepared meals.
Materials and construction
Most vacuum bags are made from multi-layer plastic, often combining polyethylene and nylon. This structure provides:
Strength and puncture resistance
Low oxygen permeability
Flexibility for sealing
We recommend choosing BPA-free and food-safe certified materials for peace of mind.
How to choose the right vacuum sealer bags
1. Match your machine
Not all bags work with all machines. External sealers require embossed bags, while chamber machines use smooth bags.
2. Consider food type
Liquids: use thicker or chamber bags
Meat: choose puncture-resistant options
Dry goods: standard bags are fine
3. Size and format
Rolls allow custom sizing, while pre-cut bags offer convenience. Choose based on how often you seal and portion sizes.
4. Storage goals
If you are freezing long term, prioritise thicker, freezer-grade bags.
For broader kitchen optimisation, it also helps to review guides like pot and pan set guide NZ to align your tools and storage approach.
Care and safe use
Do not overfill bags
Keep sealing area clean and dry
Avoid sharp bones unless using heavy-duty bags
Label and date your food
Common mistakes to avoid
Using the wrong bag type for your machine
Sealing liquids without proper technique
Reusing single-use bags unsafely
Not leaving enough space for sealing

VACSY® - MASTER OF FOOD PRESERVATION
VacSy® is a worldwide-patented food vacuum system - designed to create a vacuum inside special glass containers and special air-tight bags. The vacuum environment deprives bacteria, moulds and fungi of the oxygen needed for survival and maintains the flavour and nutritional properties of the food in an unaltered state! Food stays fresh and healthy for up to 5 times longer than in the normal refrigerator conditions.
The VacSy® System can be used to vacuum-pack fresh or prepared foods directly in VacSy® Containers, Zepter Cookware, Bottles and VacSy® Rolls.
The VacSy® System protects food from premature spoilage making it easy to plan ahead and buy food in larger volumes, thus saving on grocery purchases and on time spent shopping.
To preserve the food’s nutritional properties while cooking, use Zepter Masterpiece Cookware, which enables you to cook without fats, water and salt, at low temperatures. Food retains its full flavour, vitamins and organoleptic properties. Stored in VacSy®, daily meals remain fresh, healthy and tasty for up to 5 times longer.
