Beschreibung
Zusammenfassung:	A polyethylene powder having a viscosity average molecular weight of 100,000 or more and 2,500,000 or less, wherein, in a torque curve obtained when kneading the polyethylene powder under the following using a Labo Plastomill, a slope of a straight line connecting two local maximum points is 2 N.m/min or more and 15 N.m/min or less:After 24 g of liquid paraffin is kneaded for 10 minutes using a Labo Plastomill Mixer, produced by Toyo Seiki Seisaku-sho, Ltd. (unit model: 30C150, mixer model: R-60) at a set temperature of 114°C and a rotation speed of 5 rpm, 16 g of the polyethylene powder and 0.4 g of an antioxidant are added thereto, followed by kneading at a rotation speed of 30 rpm for 3 minutes, and then the set temperature is raised from 114°C to 163°C over 1 minute; and after the temperature rise, the mixture is kneaded at a set temperature of 163°C and a rotation speed of 30 rpm for 5 minutes.
