Vacuum skin packaging works by combining a high barrier film with a pre-made tray. The VSP film encapsulates the food product and becomes like a second skin, eliminating almost all package atmosphere. The high-barrier flexible film is softened using heat and the pull from the vacuum inside the sealing chamber, which allows it to conform to the shape of the rigid tray or laminated paperboard sheet. The ultimate goal of vacuum skin packaging is to create an attractive package that allows the consumer to view the product in its entirety.
