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.
