Abstract
A method for producing a polyolefin stretched sheet which comprises extruding a polyolefin having a weight average molecular weight of 100,000 to 500,000 into a primary sheet, rolling the primary sheet at a rolling magnification of 5 or more, and stretching the rolled sheet into a polyolefin sheet which is totally stretched at a stretching magnification of 15 or more. The method can be employed for producing a polyolefin stretched sheet excellent in creep resistance, tensile strength and modulus in tension, with no use of a ultra-high molecular weight polyethylene and with excellent productivity.
