ABSTRACT:
A stretch wrap film having one-sided cling of a thermoplastic A/B layer film structure wherein layer A in its stretched condition has a comparatively high cling force to layer B and layer B has at least substantially no cling force to a layer of itself and has a slide property when layer B is in contact with a layer of itself with relative motion therebetween and the surface of layer B presents sufficient area of an organic polymer which of its very nature causes the no cling force and the slide property.
