Aluminum Foil Packing With Vacuum

Vacuum packing is a method of packaging that removes air from the aluminum foil bags prior to sealing. This method involves placing items in an aluminum foil package and removing air from inside before sealing the package. The primary purpose of vacuum packing is to extend the shelf life of products with flexible package forms by eliminating air, which can cause oxidation and spoilage.

Aluminum barrier foil boasts a considerably lower water vapor transmission rate than bags made of LDPE or HDPE, reducing the need for desiccants in export packaging. It is the preferred choice for seaworthy and export shipments that endure long voyages through high-humidity environments, such as those encountered at sea. The high humidity in the atmosphere can lead to corrosion and rusting of products, but vacuum packing prevents oxidation by creating a protective barrier between the product and the atmosphere.

During the vacuum packing process, the chamber is filled with the product to be packaged and pressurized to remove air, ensuring that the product remains fresh and protected throughout its journey.
