Abstract

The invention disclosed herein relates to a method of making a monolayer or multilayer film structure as well as to a method of making a unitized pallet of goods wherein the pallet is stretched wrapped with the film structure. The film structure in each method comprises a polymer blend which contains at least one branched polymer (e.g. low density polyethylene (LDPE) or ethylene/vinyl acetate copolymer (EVA) and at least one linear polyethylene (e.g., LLDPE). The film structure is characterized as having a good overall balance of properties, including high ultimate elongation, excellent load retention and good machine direction tear.
