A film structure which includes at least one layer of an olefin homo-, co- or ter-polymer having a surface-treated external surface which is printable, sealable and machinable, the layer containing, as combined slip agent and antiblock, a particulate cross-linked hydrocarbyl- substituted polysiloxane, preferably a cross-linked polymonoalkylsiloxane, and/or liquid polydimethyl siloxane. A method of producing a heat sealable multilayer film structure of improved machinability is also provided.
Cette invention se rapporte à une structure de film, qui contient au moins une couche d'un homopolymère, copolymère ou terpolymère d'oléfine ayant une surface externe traitée extérieurement qui est imprimable, scellable et usinable, ladite couche contenant, ent tant qu'agent glissant et agent antiadhérent combinés, un polysiloxane à substitution hydrocarbile réticulé particulaire, de préférence un polymonoalkyle siloxane réticulé, et/ou un siloxane polydiméthylique liquide. Un procédé pour produire une structure de film multicouche thermoscellable ayant une usinabilité améliorée est également décrit.
