Abstract: Provided is an oriented, opaque polypropylene film, methods of making the oriented, opaque film, and methods of enveloping an article in a VFFS or HFFS unit using the film, the film comprising at least one core layer having a first and second side comprising polypropylene and from 2 wt % to 30 wt % calcium carbonate and from 0.5 wt % to 20 wt % of a whitening agent, each based on the weight of the core layer materials; at least one skin layer adhered to each of the first and second sides of the core layer; wherein the film possesses a density within the range from 0.65 g/cc to 0.88 g/cc and an interfacial adhesion of at least 600 g/inch.

Abstract: A metallized multilayer film structure includes a core layer of a film-forming polyolefin having a first side and a second side. A metal receiving skin layer may be disposed on the first side of the core layer. A metal layer may be deposited on the surface of the metal receiving skin layer opposite the core layer. A topcoat layer may be disposed on the surface of the metal layer opposite the metal receiving skin layer. A polymer skin layer may be disposed on the second side of the core layer. The film structure may optionally include one or more tie layers. The film structure may also optionally include a primer layer interposed between the topcoat layer and the metal layer. The present metallized multilayer film structure may be suitable for use as a monoweb to package product as opposed to being used in a lamination. The film structure exhibits superior scratch resistance and resistance to other types of damage. The film structure may be directly surface printed and then used to directly package product.
