Abstract

See full text

A biaxially oriented transfer metallizing film based on polypropylene, and process therefor. The film is a three-layer film produced by coextrusion and having a base layer of a propylene homopolymer and top layers applied to the two surfaces thereof. The base layer contains an additive depot of migrating monomers in an amount of 0.01 to 2.0 percent by weight, relative to the weight of the polymer constituting the base layer. The top layers are polypropylene that has a lower viscosity than the polypropylene of the base layer.
