Method of manufacturing a high doi/high gloss multifunctional thermoplastic film

A method of making a high gloss multilayer thermoplastic film comprising:

• (a) forming a molten coextrudate of polymeric film layers, said polymeric film layers comprising:
• at least one polyolefin core layer having a first side and a second side;
• at least one first thermoplastic skin layer having an outer surface wherein said first thermoplastic skin layer overlies the first side of the core layer;
• and
• at least one second thermoplastic skin layer having an outer surface wherein said second thermoplastic skin layer overlies the second side of the core layer;
• wherein the composition of the core layer is different than the composition of the skin layers and the core layer and the skin layers being characterized by the absence of polyvinyl chloride;
• and
• (b) pinning said molten coextrudate onto a cooled casting roll having a surface roughness of no more than Ra=0.025 microinches with a pinning roll under sufficient pressure to produce a film having a smooth first skin layer outer surface, wherein said smooth first skin layer outer surface has a ratio of distinctness of image in the machine direction to distinctness of image in the cross direction in the range of 1:1 to 1.3:1 and has a 20° gloss in both the machine direction and the cross direction is at least 40.
