Abstract

Medium modulus polyethylene films with improved tear performance are made for heavy-duty packaging applications and hot-fill uses. Film compositions contain high molecular weight linear polyethylene and a substantially linear ethylene/.alpha.-olefin interpolymer. The film is at least about 1.25 mils (31 microns) thick, has a film density in the range of 0.923 to 0.95 grams/cubic centimeter (g/cc) and typically has a tear strength or impact resistance at least 30 percent greater than current industrial polyethylene film. The novel film has good dimensional stability and strength poroperties which allow significant down-gauging savings.
