COMPOSITE FILM FOR PACKING

摘要

PURPOSE:To prevent the release of the base material and intermediate layer composed of straight chain linear low density polyethylene of a composite film used in a packing bag even when said film is preserved over a long period of time and to develop the antistatic effect of the inner surface layer thereof over a long period of time. CONSTITUTION:A composite film is constituted by laminating and bonding a straight chain linear low density polyethylene layer 3 to the surface of a base material layer 1 through an anchor coat layer 2 and laminating and bonding an inner surface layer 4 composed of an ethylenic resin film containing 0.1-2wt.% of an antistatic agent to the surface of the straight chain linear low density polyethylene film layer 3, and the straight chain linear low density polyethylene film layer 3 being an intermediate layer, prevents the transfer of the antistatic agent.
