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 .
