Start with the sealer type
Most home users want an external suction sealer. It is cheaper, compact and uses textured/channel bags. Chamber sealers handle liquids and repeated sealing better, but they are much larger and more expensive.
Features that actually matter
- Moist mode: useful when food has surface moisture.
- Pulse/manual vacuum: lets you stop delicate foods being crushed.
- Integrated roll cutter: reduces friction when making custom bags.
- Accessory port: useful for compatible containers.
- Replaceable seals/gaskets: can extend useful life.
Do not ignore bag cost
A cheap machine tied to expensive proprietary bags can cost more over time than a slightly dearer model using widely available channel rolls.
Sunbeam FoodSaver VS7850: why it is worth researching
The FoodSaver VS7850 is a long-running Australian model with integrated roll storage/cutter, moist-food settings and accessory support. Public owner reviews are mixed enough that warranty and long-term reliability deserve consideration, which is exactly why we do not present it as an automatic “best”.
Check current listingsWhen to consider a chamber sealer
Only step up if you regularly seal liquids, do high-volume batch prep or have a genuine use for cheaper smooth chamber pouches. For most homes, the size and initial cost are overkill.

FAQ
Can any plastic bag be vacuum sealed?
No. External suction sealers usually need embossed/channel bags. Follow the machine and bag manufacturer instructions.
Does vacuum sealing make food shelf-stable?
No. Vacuum sealing changes the atmosphere around food but does not sterilise it. Refrigeration, freezing and food-safety rules still apply.
