What is the advantage of a chamber vacuum sealer?
Chamber vacuum sealers evacuate air from the chamber, leaving the air pressure equal both inside and outside the pouch and keeping liquids securely inside the pouch. The chamber vacuum sealer does not use any suction, which allows you to vacuum package soups, stews, marinades and other liquids.
Unlike a regular vacuum sealer, a chamber vacuum sealer pumps all of the air (including air inside the bag) out of the chamber at once, giving your item a truly airtight seal. The sealing process ends with the machine heating the edges to fuse the bag and prevent air from coming inside.
