Beschreibung
Zusammenfassung:	The invention concerns polymeric films including a layer of polypropylene homopolymer with a layer of voided polypropylene on one side and a layer of a printable polymer on the other side. The printable polymer is preferably an acrylic polymer, a co- or terpolymer containing units derived from at least two of ethylene, propylene or but-1-ene, and/or a linear low density polyethylene. Films of the present invention have good gloss combined with printablilty and a pearlescent effect. They can also provide evidence of tampering with packaged goods.
