Abstract: A method for preparing a pre-stretched film includes extruding a multi-layered film that has an initial overall film thickness of 24 ?m to 35 ?m and stretching the multi-layered film from the initial film thickness to a final film thickness of less than 12 ?m to form a pre-stretched film. The multi-layered film has a first layer that includes an ultra low density polyethylene having a density less than 0.910 g/cm3 and has second and third layers that each independently includes a linear low density polyethylene having a density of 0.910 g/cm3 to 0.94 g/cm3. The pre-stretched film is capable of exhibiting an ultimate stretch of less than 28% at an applied weight of 45 kg and less based on a percent change in thickness of the pre-stretched film prior to application of the applied weight compared to after application of the applied weight.

Abstract: A method for improving the efficacy of polar additives used in polyolefins is disclosed. The method is related to the addition of an effective amount of a co-additive compound of the formula R1(OCH2CH2)xOH to the polyolefin prior to forming the film, wherein R1 is a straight or branched chain alkyl of 20 to 100 carbon atoms and x is 2 to 100. The presence of these materials in polyolefin resins allows less polar additives to be used without losing their efficacy and also leads to improved optical properties for films made from such resins.

Abstract: Provided are monolayer and multilayer films having improved barrier properties. The monolayer film is a blend of two components: (1) a linear low density polyethylene and (2) a propylene-based polymer, a high density polyethylene, and combinations thereof. The propylene-based polymer can be a propylene homopolymer, a propylene/a-olefin interpolymer, a propyleve/ethylene interpolymer, or a propylene/ethylene copolymer. The multilayer film has an inner layer located between two outer layers. The inner layer is composed of one or more of the following: high density polyethylene, and/or any of the foregoing propylene-based polymers. The outer layers may be the same or different and are composed of one or more of the following: linear low density polyethylene, high density polyethylene, and any of the foregoing propylene-based polymers. The present films exhibit proved oxygen barrier properties particularly for balage applications.
