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 cross-linked hydrocarbyl substituted polysiloxane, and which is located on one side of a cor...

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 cross-linked 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 cross-linked 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 1.15 to 2.5. Une structure de film comprend une première couche de revêtement extérieur (a) constituée de co- ou de terpolymère d'oléfine ayant une surface extérieure qui peut être scellée et usinée, la première couche de revêtement contenant un polysiloxane particulaire, réticulé et à substitution hydrocarbyle, et qui est située sur un côté d'une couche de polymère oléfinique (b); sur un côté opposé de la couche centrale, une deuxième couche de revêtement (c) qui est un homopolymère d'éthylène et qui est exempte du polysiloxane réticulé à substitution hydrocarbyle de la première couche de revêtement. Dans un mode de réalisation, le rapport entre la taille particule et l'épaisseur de la couche de revêtement (a) est compris entre 1,25 et 2,5, ce qui augmente les propriétés barrière.
