HIGH BARRIER ANTIFOG LAMINATE FOR CASE READY MEAT PACKAGING

摘要

A multilayered packaging film having good antifog performance that is suitable for use in food packaging. The multilayered film comprises an outer film attached to an inner film, which outer film is a combination of a first nylon layer, an ethylene vinyl alcohol layer attached to a surface of the first nylon layer and a second nylon layer attached to the ethylene vinyl alcohol layer. The inner film is a combination of a third nylon layer having a silicone oil on a first surface of the third nylon layer, and a sealant film on a second surface of the third nylon layer, attached either directly or via an intermediate adhesive layer. An antifog composition is either contained within the sealant film or is coated on a surface of the sealant film opposite the third nylon layer. The silicone oil effectively blocks the migration of the antifog composition into an adjacent nylon layer when the multilayered film is stored in roll form.
