A polyolefin multilayer film containing a polyolefinic core layer and a first polyolefin skin layer of a blend, wherein the first polyolefin skin layer does not contain a thermoplastic or natural rubber and provides a cold seal receptive surface for a cold seal adhesive is disclosed. The blend includes an ethylene propylene random copolymer at 50-90 wt. % of the skin layer and metallocene catalyzed plastomer at 10-50% wt. % of the skin layer, a metallocene catalyzed isotactic polypropylene polymer or a butene propylene copolymer that contains from 5 wt % to 22 wt % of butene.

Polypropylene film for use in cold seal cohesive applications

Polyolefin film for use in cold seal cohesive applications

A biaxially oriented polyolefin multilayer film having a skin layer having oil-absorbing voids is disclosed. The film has substantially a small amount of void-initiating particles in the skin layer and typically no fillers in the core layer. Yet the film shows no visible distortion after exposure to food products such as potato chips.

Polyolefin oil resistant film using void initiating solid particles

A biaxially oriented polyolefin multilayer film having a skin layer having oil-absorbing porous particles is disclosed. The film has substantially a small amount of porous particles on a weight basis of the total weight of the film and yet shows substantially no visible distortion after exposure to food products such as potato chips.

Polyolefin oil resistant film using porous particles

A biaxially oriented polyolefin multilayer film having a skin layer made of a blend of a polar polymer and a non-polar polymer is disclosed. The film has substantially no inorganic fillers and yet shows no visible distortion after exposure to food products such as potato chips.

Polyolefin oil resistant film using polar polymer

A laminate film comprising a polymer core layer; a resin layer disposed on a surface of the polymer layer; and a metal layer deposited on a surface of said resin layer; wherein the laminate film has excellent adhesion between the resin layer and the metal layer and barrier durability is disclosed.

Biaxially oriented polypropylene metallized film for packaging

A biaxially oriented polyolefin multilayer film having a skin layer made of a blend of a crystalline wax and a non-polar polymer is disclosed. The film has substantially no inorganic fillers and yet shows no visible distortion after exposure to food products such as potato chips.
