Film structure

A 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...

description A 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 skin layer c which is ethylene homopolymer and which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from 1.25 to 2.5.
