Abstract
Multilayer thermoplastic stretch wrap film having substantial one-sided cling properties is made without the use of polymers with high levels of n-hexane extractables, dissimilar polymer chemistries, or low molecular weight tackifiers. The reverse or cling layer comprises at least one homogeneously branched ethylene polymer composition having a density of about 0.90 g/cc or less and the obverse or non-cling layer comprises an propylene or ethylene polymer composition having a density greater than 0.90 g/cc. The multilayer film is particularly useful for load palletization end-use applications.
