PEEL MECHANISM FOR PEELABLE BARRIER FILM FOR VACUUM SKIN PACKAGES AND THE LIKE |
摘要 |
A composite film and vacuum skin package for packaging a product such as a fresh red meat is disclosed. The composite film is thermoformed and sealed under vacuum to a support member to completely enclose a product which is positioned on the support member. The composite film is a gas-permeable film weakly bonded to a gas-impermeable film, permitting the gas-impermeable film to be peeled from the package while leaving the gas-permeable film intact so that the fresh red meat product can bloom from a purplish color to a desirable red color upon exposure to oxygen. A peel initiation mechanism which is a grippable film sealed along an edge of the gas-impermeable film is provided.
