ABSTRACT:
The invention is directed to a composition suitable for use in a single-sided stretch cling film, the composition having from 0.1 to 20 percent by weight of a propylene-based copolymer having substantially isotactic propylene sequences, and having from 80 to 99 percent by weight of an ethylene-based copolymer having a density of at least 0.905 g/cc, wherein a film made from the composition exhibits cling layer to release layer cling of at least 70 grams force per inch as measured by ASTM D-5458-95, noise levels of less than 87 dB during unwinding operations, and has a modulus of at least 3 MPA as determined by ASTM D-882.
