Abstract: A process for producing a composition comprising A) an ethylene-based polymer that has a density greater than, or equal to, 0.940 g/cc, and B) an ethylene homopolymer formed by polymerizing a reaction mixture comprising ethylene, using a free-radical, high pressure polymerization process includes adding component (A) to a molten stream of component (B) after component (B) exits the separator and before component (B) is solidified in the pelletizer. A polymerization configuration for producing the composition includes at least one reactor, at least one separator, at least one pelletizer, and a device used to feed component (A), in the molten state, to a molten stream of component (B) before the pelletizer. The composition has a ratio of the melt strength of the composition to the melt strength of component (B) is greater than or equal to 1.04 and a density of greater than 0.920 g/cc.

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.
