BIAXIALLY ORIENTED, MULTILAYER POLYPROPYLENE FILM, PROCESS FOR THE PRODUCTION THEREOF AND THE USE THEREOF

摘要

The disclosed biaxially oriented, multilayer polypropylene film comprises at least one base layer B, one interlayer Z and one top layer D and contains migrating additives. The film contains a maximum of 0.15% by weight of migrating additives, based on the total weight of the film. The multilayer film structure is produced by coextrusion and biaxial stretching followed by heat-setting and, optionally, corona treatment. The film is particularly useful in packaging and in laminates.
