Abstract: A film comprising a) at least one base layer comprising a thermoplastic polymeric matrix material; and b) a skin layer comprising a thermoplastic polymeric matrix material and from 5 wt % to 80 wt % of polymeric particles having an average particle diameter from 0.5 ?m to 15 ?m, a refractive index from 1.46 to 1.7, and at least 60 mole % of acrylic monomer units wherein the film is stretched by a factor of 2 to 8 uniaxially or biaxially; and wherein after stretching, the skin layer has a thickness that is between 50% and 200% of the diameter of the polymeric particles, and a method of making the film, are disclosed.

Abstract: Laminates of polymeric films and solvent-based polyurethane adhesive formulations for preparing them are provided. The adhesive formulations include a hydroxyl-terminated polyester that forms crystalline polyester domains after reaction with an appropriate polyisocyanate, but prior to completion of cure. The result is an adhesive layer that substantially enhances the oxygen barrier properties of the adhesive and, therefore, of the laminate as a whole, while offering desirable convenience of application even at relatively low temperatures. The laminates may also exhibit desirable retention of barrier properties following flex-cracking.
