ABSTRACT:
A polymeric film prepared from a relatively crystalline polymer such as a copolymer of ethylene and an .alpha.-olefin having at least 3 carbon atoms, e.g., 1-octene (linear low density polyethylene); a relatively amorphous polymer such as low density polyethylene and a tackifying polymer such as a low molecular weight polybutene exhibits a substantially higher cling on one side than the other.
A film of a low density polyethylene, linear low density polyethylene and a low molecular weight polybutene also exhibits excellent film strengths and as unexpectedly high resistance to tear, particularly in the cross-direction.
