Vacuum sealing bar

A sealing bar vacuum sealer is a device used to remove air from bags containing food or other items, creating a vacuum that helps preserve freshness and extend shelf life. The sealing bar is a component of the machine that uses heat to hermetically seal the bag, maintaining the vacuum created.

• How it works: The machine sucks air from the bag, creating a low-pressure environment inside.
• Sealing Bar: This bar, when heated, melts and seals the edge of the bag, preventing air from re-entering.
• Use: Sealing bar vacuum sealers are suitable for both home and professional use and can be used to preserve fresh or cooked foods, or even to protect items from dust and moisture.
• Benefits: Vacuum sealing helps slow bacterial growth, reduces oxidation, and preserves the organoleptic properties of foods.
• Types: There are chamber machines, where the bag is inserted into a chamber, and external suction machines, where the bag is sealed outside the machine.
