ABSTRACT:
The present invention relates to oriented or hot-blown shrink films which may be manufactured from by a number of processes. The oriented films may be manufactured by double bubble, LISIM, tape bubble, trapped bubble or tenter framing processes. The films of the present invention are useful as a shrink film to package and label a variety of products. The films exhibit a high degree of MD shrinkage in a very controlled and consistent manner while providing a number of other positive characteristics such as optical clarity, puncture and abrasion resistance, controlled gauge, and superior web winding and handling characteristics. The shrink control layers of the films of the present invention contain a modifier component selected from plastomers and/or metallocene catalyzed ethylene-propylene copolymers and blends thereof.
