(unit model: C, 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.",
