摘要： Methods and means for producing a stretch film comprising a slip skin layer are provided. In one example embodiment, a stretch film having a slip skin layer is provided having a variable and scalable coefficient of friction. A stretch film comprising a cling layer and a slip skin layer is also provided, in which the cling layer further with includes a polyethylene-based elastomer blended into a low density polyethylene, and the slip skin layer includes an ultra-high molecular weight polysiloxane polymer. Consequently, the slip skin layer has a very low coefficient of friction while the cling layer retains a relatively high co-efficient of friction.
