Abstract
Shrink films prepared from metallocene catalyzed propylene homopolymers and copolymers are provided. The films exhibit a unique balance of properties as compared to known shrink films including higher stiffness, tensile strength and moisture barrier, lower extractables, improved shrinkage and increased shrink tension. In addition, the shrink behavior of the film can be substantially tailored by modifying the amount of comonomer present in the propylene polymer.
