What Is a Vacuum Sealer?
A
vacuum sealer is a device used for packaging food or other items by removing air from the packaging. It consists of a sealing mechanism and a vacuum pump. The process involves placing the item to be sealed inside a specially designed bag or container, inserting the open end of the bag into the sealer, and activating the machine. The vacuum pump then removes the air from the bag, creating a vacuum environment. Once the desired level of vacuum is achieved, the sealer automatically seals the bag, preventing any air from reentering. This process helps to extend the shelf life of the packaged items by reducing the presence of oxygen, which can lead to spoilage.
Vacuum sealers are commonly used in households, restaurants, and industries that require long-term storage of perishable goods.
