Abstract

A decorative packaging film comprises a base film of a synthetic polymeric material (an olefinic polymer) containing a highly light absorbent pigment, for example carbon black, and at least one surface layer of a second synthetic polymeric material, which is light transmittable and which contains a solid particulate material, for example calcium carbonate, having a particle size of from 0.1 to 10 microns and present in an amount from 1 to 40% by weight, the combination having been stretched to cause the formation of voids in the surface layer or layers at the sites of the particles of the particulate material. The appearance of the film varies from an intense opalescence to a lustrous metallic appearance.
