Medium modulus film and fabrication method |
摘要 |
Medium modulus, polyethylene films and bags with improved tear performance are made for heavy-duty packaging applications and hot-fill uses. Film compositions contain high molecular weight linear polyethylene and linear ethylene/ alpha -olefin interpolymer. The film is at least about 1.25 mils (31 microns) thick and is characterized as having a calculated film density in the range of about 0.923 to about 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 superior dimensional stability and strength properties which allow significant down-gauging relative to industrial films used as heavy-duty overwraps, sleeves and bags. |
