Abstract: A cavitated opaque polymer film, including (i) a beta-cavitated core layer containing a propylene polymer and an impact copolymer and (ii) a matte surface layer with sufficient roughness to serve as a mold-ready skin layer. The core layer may optionally contain a beta cavitating agent. Cavitated opaque labels including: a cavitated core layer; a support layer on one side of the core layer, the support layer containing a thermoplastic polymer; and a matte layer on the side of the core layer opposite the support layer. The core layer contains a propylene polymer, a beta nucleating agent, and an impact copolymer; the matte layer contains at least one of a matte-resin and a matte-surface producing agent. The matte surface outer layer may provide sufficient roughness to provide labels that are mold-ready for IML applications, without need for an adhesive pattern or coating.

Abstract: A biaxially oriented thermoplastic structure including a low density core layer formed from polypropylene, highly crystalline polypropylene or high density polyethylene, and outer layers formed from highly crystalline polypropylene or high density polyethylene. The thickness of the core layer is about 60 to about 95% of the overall thickness of the structure. The stiffness of the structure in the machine direction is in a range from about 0.015 to about 0.15 pound force-centimeters.

Abstract: A polymeric film structure having a removable scratch off layer particularly suitable for use on “scratch and reveal” devices including instant lottery tickets, “scratch and win” game cards, and various other promotional items. The film structure includes an opaque cavitated layer secured to an adjacent layer along a weakened interface. The cavitated layer initially conceals certain preprinted indicia, e.g., prize information, but may be subsequently removed by scratching and/or rubbing to allow viewing of such indicia.
