MULTILAYER METALLISED FILM

摘要

A multilayer metallised film and a method of forming the film are disclosed. The method comprises a step of extruding a first polymer between a metallised layer and a film of a second polymer to form the multilayer metallised film. The first extruded polymer includes one or more than one polymer additive that is selected to control the adhesion of the extruded first polymer or polymer blend to the metallised layer such that an adhesion force between the first extruded polymer and the metallised layer is lower than an adhesion force between the metallised layer and the supporting film.
