The invention relates to a melt molding material wherein the unexpected production of particles during continuous melt molding can be inhibited. More specifically, the present invention relates to a melt, columnar, flat or spherical molding material comprising an ethylene / vinyl alcohol copolymer, the side surface having a roughness (Rz) (maximum profile height) of less than or equal to 300 μm. It is preferable that the lateral surface has a roughness (Ra) (arithmetic average deviation of the profile) less than or equal to 50 μm. It is preferred that the melt molding material has a particle size distribution in terms of equivalent circular diameter, which has a width at half height less than or equal to 1 mm. The ethylene / vinyl alcohol copolymer preferably has an ethylene unit content of 20 to 60 mol%. |
