ABSTRACT:
The multilayer shrink film of the present invention provides very low shrink tension approximating some PVC films, while providing relatively high free shrink characteristics and relatively low shrink temperatures. The preferred film has three layers including a relatively thick core layer comprising a polymeric material or blend of polymeric materials having a relatively low melting point, typically less than about 100° C., two outer layers comprising a polymeric material or blend of polymeric materials having a relatively high melting point, typically greater than about 100° C., the material of the outer layers having a melting point at least about 10° C. higher than the melting point of the material of the core layer.
