PURPOSE:To reduce blocking of pellets to each other by forming a polymer pellet using a crystalline polyolefin as a sheath and a polymeric composition of a thermoplastic elastomer or amorphous polyolefin and the crystalline polyolefin as a core. CONSTITUTION:A crystalline polyolefin A is used as a sheath part 1. A polymeric composition of the crystalline polyolefin A and a thermoplastic elastomer or amorphous polyolefin B is used as a core part 2. A polymer pellet is made of the sheath part 1 and the core part 2. in this manner, since the polymeric composition having blocking properties is coated with the sheath part 1, the blocking phenomenon of the pellets is suppressed, and the handleability of the pellets is enhanced. |
