EASILY PEELABLE MULTI-LAYER COMPOSITE FILM

摘要

PROBLEM TO BE SOLVED: To provide an easily peelable transparent film showing a satisfactory easy peeling function. SOLUTION: This multi-layer composite film is constituted of an ethylene-vinyl alcohol copolymer resin layer with an ethylene content of 29 to 47 mol%, a polycycloolefin resin(COP) layer with a glass transition temperature(Tg) of 60 to 80°C and a sealing layer composed of a polyethylene resin and/or an ethylene-vinyl acetate copolymer resin. The described problem is solved by arranging the COP layer adjacent to the sealing layer. COPYRIGHT: (C)2004,JPO
