| 摘要 |
<p>PROBLEM TO BE SOLVED: To provide an ethylenic polymer film having high quality and a method for producing the film. SOLUTION: A film having 0.4-1.2 mil gauge, a final elongation of >=280% and a penetration resistance of >=250 ft-1 sbs/cm<3> is produced by the extrusion of an ethylene/α-olefin copolymer in the form of a film using a copolymer having a high-density fraction of >17% and an Mw /Mn ratio of <3.6 as the ethylene/α-olefin copolymer.</p> |
