Polyester strapping made from polyester and less than 3% by weight of a polyolefin additive exhibits improved resistance to longitudinal splitting when the strapping is later placed under tension in packaging reinforcement applications. The polyolefin improves the longitudinal split resistance of the strapping without facilitating unwanted longitudinal stretch of the polyester strapping when under tension. The polyolefin additive may be combined with other conventional additives, or may be used alone in order to minimize costs.

High integrity polyester strapping

A cling film system includes first and second film piles having different composition. Each film ply includes at least one cling layer and, desirably, one or more additional layers. Each film ply includes an overlapping portion and a second portion. The cling layer of the first film ply engages the cling layer of the second film ply in the overlapping portion of the first film ply and in the overlapping portion of the second film ply.
