METALLIZED FILM STRUCTURE

摘要

A metallized film structure comprises a first outer skin layer (a) of an olefin co- or terpolymer having an external surface which is sealable and machinable, the first skin layer containing a non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane, and which is located on one side of a core olefinic polymer layer (b), on an opposite side of the core layer there is a second outer skin layer (c) which is an ethylene homopolymer which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer having a metal deposited thereon. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from about 1.25 to about 2.5./!
