  • Patent number: 7572519
    Abstract: A multilayer stretch film comprising at least a first layer (i) with cling properties comprising an olefin (co)polymer composition, a second layer (ii) with slip properties comprising another olefin (co)polymer composition and if desired at least one core layer (iii) comprising an olefin (co)polymer composition between the first layer (i) and the second layer (ii). The outer surface of the first layer (i) with cling properties is provided with a non-stretchable thin film of one or more slip agent(s) covering at least 50% up to 100% of the outer surface of the first layer (i), lowering the cling properties of the unstretched composite film. The thin film of slip agent(s) is provided either by direct application of the slip agent(s) onto the outer surface or by use of slip agent(s) having limited compatibility with the (co)polymer composition as additive in the (co)polymer composition of the first layer (i).
