METALLIZED MULTILAYER FILM

摘要

A metallized, multilayer film suitable for packaging applications is provided which comprises a first skin layer comprising a thermoplastic selected from the group consisting of high density polyethylene, ethylene vinyl alcohol copolymer, medium density polyethylene, linear low density polyethylene, ethylene-propylene-butylene terpolymer, propylene-butylene copolymer, and amorphous polyamide, a metallized layer adjacent to the first skin layer, and a core layer comprising high crystallinity polypropylene homopolymer with an intermolecular stereoregularity greater than 93%. Additionally, low density polyethylene, EMA, EVA, or EAA may be extrusion laminated to the metallized side of the metallized, multilayer film at a web tension sufficient to prevent metal crazing of the vacuum deposited aluminum layer. A method for making the film is also provided.
