ABSTRACT:
The polyolefin [A] has a weight average molecular chain length of 2850 nm or longer and a density ρ1(g/cm3), the polyolefin wax [B] has a weight average molecular weight of 700–6000 and a density ρ2(g/cm3), the polyolefin and the polyolefin wax are incorporated at [A]/[B]=90/10–50/50 (ratio by weight), and the densities ρ1and ρ2satisfy the following conditions: 0.92≦ρ1≦0.94, 0.91≦ρ2≦0.93, −0.03≦(ρ1−ρ2)≦0.03.
