Abstract: Laminate film structures including an adhesive layer having gas and moisture barrier properties are disclosed. The disclosed laminate film structures comprise films bonded together with an adhesive composition, the adhesive composition having barrier properties, e.g., controlling oxygen and/or water vapor transmission rates. The disclosed laminate film structures comprise films made from polymers and/or metallized polymers whereby the weight, thickness, and/or number of film layers has been reduced by using a barrier adhesive in place of a standard adhesive while still achieving similar barrier properties. Methods for forming laminate structures having a desired barrier performance are also disclosed, the methods comprising determining the desired barrier performance of the laminate structure, selecting a barrier adhesive, selecting two or more film layers, including at least a first film layer and a second film layer, applying the barrier adhesive on a surface of the first film layer, and bringing a surface of the second film layer into contact with the barrier adhesive applied on the surface of the first film layer, thereby forming the laminate structure having a desired barrier performance.

Abstract: The present invention provides polymer blends that can be used in a multilayer structure and to multilayer structures comprising one or more layers formed from such blends. In one aspect, a polymer blend comprises a copolymer comprising ethylene and at least one of methyl acrylate and ethyl acrylate having an acrylate content of 5 to 40 weight percent based on the weight of the copolymer and having a melt index (I2) of 1 to 60 g/10 minutes, wherein the total amount of ethylene methyl acrylate copolymer and ethylene ethyl acrylate copolymer comprises 45 to 99 weight percent of the blend based on the total weight of the blend, and a polyolefin having a density of 0.870 g/cm3 or more and having a melt index (I2) of 20 g/10 minutes or less, wherein the polyolefin comprises 1 to 55 weight percent of the blend based on the total weight of the blend.
