ABSTRACT:
The present invention relates to a method for making a multilayer coextruded thermoplastic stretch wrap film useful for the packaging or pelletizing of goods. More particularly films made according to this invention include at least three layers: two outer layers and an intermediate layer positioned between the outer layers. The intermediate layer contains a mixture of a first linear low density polyethylene and a polyolefin selected for the group consisting of homopolymers of propylene, copolymers of propylene and ethylene and mixtures thereof. At least one of the two outer layers is a second polyethylene. The force required to stretch films made according to this method is controlled by varying the intermediate layer blend ratio between 85% polyethylene/15% propylene and 95% polyethylene/5% propylene.
