The Bonsenkitchen edge sealer is our best choice for regular freezer portions and batch cooking. It makes heat-sealed bags from a roll, has a built-in cutter and offers pulse and extended-seal controls. If you mainly want to reseal fridge containers, the compact CASO Vacu OneTouch Eco is a better fit. The Mesliese is worth considering when you regularly handle damp ingredients and want a double heat seal.
These are research-led recommendations, not hands-on reviews. We compared the linked products’ bag systems, supplied accessories, controls and storage demands. We have not used the machines or measured their suction, sealing speed or long-term reliability. Some features below are seller specifications, not our test results.
Our direct answer
Choose by bag format before comparing suction figures. The CASO uses a handheld pump, valve-equipped reusable zip bags and containers: convenient for food you open and reseal. The Bonsenkitchen and Mesliese are countertop edge sealers. They draw air from suitable bags and heat-seal the open end, which is more practical for making many freezer portions. The meal-prep equipment guide can help you decide whether either format deserves cupboard space.
The Bonsenkitchen is the sensible middle choice for most regular users. Its listed roll compartment, cutter, bag clamp, Pulse Vac and Extended Seal settings cover common dry-food packing and offer some control when food is delicate or slightly damp. It is not a machine for sealing loose soup. Buy the CASO instead if reusable fridge storage matters more than freezer-bag production; consider the Mesliese if the double heat seal is a feature you would actually use.

The included quantities come from the linked products’ current seller descriptions; bundles can change, so check the box contents before ordering. These are three different ways to store food, not three interchangeable machines.
How we selected them
We shortlisted machines with a distinct purpose rather than filling a fixed number of places. That left a handheld reusable system, an everyday heat sealer and a double-seal option. We considered bag compatibility, what comes in the box, replacement supplies and storage space alongside controls. We have not run a durability test or verified manufacturers’ suction and speed figures, so the order is about likely buying fit rather than laboratory performance. Our guide to kitchen gadgets worth buying is a useful sense-check for occasional-use equipment.
Best vacuum sealers UK: our recommendations
1. Bonsenkitchen 15L/min sealer — best overall for routine batch prep
The linked Bonsenkitchen is a countertop edge sealer for making custom-length bags from a textured roll or closing suitable pre-cut bags. Its seller specification lists built-in roll storage, a cutter and a bag-mouth clamp, plus Vac & Seal, Pulse Vac and Extended Seal settings. Pulse control may help prevent soft food being crushed or liquid being pulled towards the seal, while an extended heat-seal setting is intended for more demanding bag edges. We have not tested how well either setting performs.
The listed starter kit includes one roll and ten pre-cut bags. That is enough to try both formats, but frequent batch cooking means buying compatible textured rolls or bags thereafter. The listed machine dimensions are approximately 41 × 22 × 12 cm; allow extra room to open the lid and feed a bag. Its claimed 15L/min pump rate is not a measured result here and should not be taken as proof that it outlasts or outpaces the other machines.
Choose it if: you regularly split supermarket packs, prepare freezer meals or want to size bags to different portions. Skip it if: you mainly want reusable fridge containers, have very little storage room or need to seal loose liquids. Its controls and starter kit are stated for the linked variant; we have not applied specifications from a different colour or bundle.
2. CASO Vacu OneTouch Eco kit — best for occasional reusable storage
The CASO is deliberately not a heat sealer. Its small cordless pump draws air through valves in compatible reusable zip bags and containers. The linked kit lists three glass containers and ten reusable bags. That makes sense for cheese, leftovers or other food you may take out and reseal during the week. The pump itself is easy to put away, although the containers still need cupboard or fridge space.
CASO’s Eco-Set product information describes the format and USB-C charging. Treat its battery-life claims as manufacturer figures; we have not timed the pump. The containers have plastic lids, so the whole system is not plastic-free. Follow the maker’s cleaning instructions, especially after storing raw food.
Choose it if: you want a reusable container-and-bag system for occasional storage and dislike leaving a large appliance on the counter. Skip it if: you want dozens of individually heat-sealed freezer portions or plan to buy generic textured rolls. Compatible replacement valve bags are the continuing cost to check.
3. Mesliese 95kPa double-seal model — best for more moist-food control
The linked Mesliese is another countertop edge sealer, but its seller specification lists two heat-seal strips, pulse control, a cutter and internal roll storage. Two rolls are listed in the starter kit. A second seal may be useful when packing food with surface moisture, provided the bag lip is clean and dry. We have not tested whether this machine seals damp bags more reliably than the Bonsenkitchen.
The stated 95kPa suction, 140W motor and 20L/min airflow are seller claims, not comparable measurements from our kitchen. We could not verify a trustworthy exact footprint for this variant, so measure your available storage space before buying. It uses suitable textured bags or rolls, which remain a recurring purchase. Its double-seal arrangement does not turn it into a chamber sealer: loose soup or marinade can still be drawn towards the edge.
Choose it if: you frequently pack slightly damp foods and value pulse control plus a double heat seal. Skip it if: you only portion dry foods, want a small handheld kit or need to vacuum loose liquids. We have not borrowed performance claims or dimensions from another Mesliese model.
What to check before buying
Check the bag system. A handheld valve kit is good for food you will reopen. A heat sealer uses compatible textured bags or rolls to make closed freezer packs. Smooth everyday freezer bags may not work in an external-suction machine. Check replacement-bag availability and cost before buying; a generous starter kit does not remove the ongoing expense.
Check the box contents. The CASO kit lists containers and reusable bags. The Bonsenkitchen lists a roll and pre-cut bags; the Mesliese lists two rolls. These are seller-stated contents, and bundles may change. If you need a hose, extra container or particular bag width, check that it is actually included for the variant you order.
Check storage and workload. The pump alone is small, but its containers occupy space. The two heat sealers need counter space and clearance to open, cut and feed bags. An internal cutter is helpful for a long batch-cooking session, but published suction figures do not tell you whether a machine needs cooling pauses. Check the exact model’s instructions if you plan to seal many bags in one go. Our batch-cooking and freezing guide covers the preparation side, our one-pot cooking guide has portionable meal ideas, and the small-kitchen organisation guide helps with storage planning.
Be realistic about wet food. Pulse control and a longer or double heat seal can help with damp edges, but cannot compensate for sauce across the sealing strip. For soup or a wet marinade, use an appropriate container or pre-freeze the contents if the machine’s instructions allow it. A chamber sealer is the different type of machine designed for regular loose-liquid work.
Using a vacuum sealer safely
Removing air does not sterilise food. Raw meat, fish and cooked leftovers still need correct chilling or freezing, and a sealed bag must not sit at room temperature because it looks protected. The Food Standards Agency’s chilling guidance advises cooling cooked food and refrigerating it within one to two hours; its leftovers guidance says to eat leftovers within 48 hours or freeze them. Observe use-by dates and keep raw food separate from ready-to-eat food.
The FSA’s vacuum-packaging guidance explains why reduced oxygen is not a substitute for temperature control. It is written for food businesses, not as a new home shelf-life allowance. Cool food safely first, keep the sealing area clean, label and date packs, and check each seal before freezing. Follow the food’s own thawing and cooking instructions.
Which one should you buy?
Choose the Bonsenkitchen if freezer portions are a regular routine and you want a roll cutter and pulse control. Choose the CASO for occasional reusable fridge storage with minimal appliance space. Choose the Mesliese if you expect to use its double seal and moisture-oriented controls often. We have not used any of them, and if sealing will be rare, your existing containers and freezer bags may be the better choice.
Frequently Asked Questions
Can I use ordinary freezer bags in a vacuum sealer? Not automatically. Edge sealers usually require the textured bag format specified by the maker. The CASO pump uses compatible valve-equipped bags or containers, not heat-sealed rolls.
Which vacuum sealer is best for soup? None of these is a chamber sealer for loose liquid. Use a suitable container or pre-freeze soup before bagging if the machine’s instructions permit it. Keep the heat-seal edge dry.
Is a handheld vacuum sealer the same as an edge sealer? No. The CASO draws air through a valve in a reusable bag or container. The Bonsenkitchen and Mesliese remove air from suitable bags and heat-seal the open edge.
Do I need a double heat seal? It is worth considering if you regularly pack slightly damp foods and want an additional sealing barrier. It does not make a dirty or wet bag lip seal reliably. We have not tested the difference between these machines.
Does vacuum sealing make chilled food safe for longer? Do not use a home sealer to override a use-by date or normal chilling guidance. Keep perishables cold, cool cooked food promptly and freeze it when appropriate.
What supplies will I need after the starter kit runs out? The CASO needs compatible valve bags if you want more than those supplied. The heat sealers need compatible textured rolls or pre-cut bags. Check bag width, availability and replacement cost for the model you choose.
