The purpose of the invention is to provide: a package for EVOH resin pellets which is capable of providing the EVOH resin pellets almost free from powder even in a case where the package contains the powder generated therein during transportation or the like after shipment; and EVOH resin pellets contaminated with very small amount of the powder in a case where a user uses the EVOH resin pellets as a molding material. A package, where pellets each having a substantially circular or oval cross-section are packed in a packaging container whose inner surface has a surface resistivity of 1.0×1014Ω or more, is capable of providing pellets to which 0.8 wt % or less of powder adhered relative to the weight of the pellets.
A package comprising pellets made of saponified ethylene-vinyl ester-based copolymer or resin composition thereof, and a packaging container in which the pellets are packed, wherein the inside surface of the packaging container has a surface resistivity of 1.0×1014Ω or more, the surface resistivity being measured according to JIS K6911 with respect to the inside surface of the packaging container after moisture conditioned by being placed for 24 hours in a bath where the constant condition of 23° C. and 50% RH being set, and wherein each of the pellets has no edge and an approximately circular or oval cross-section.
A method for reducing powder adhered to the surface of pellets made of saponified ethylene-vinyl ester-based copolymer or resin composition thereof, the pellets each having an approximately circular or oval cross-section and no edge, and the pellets obtained from a package therefor, characterized by that a packaging container for packing the pellets has an inside surface of surface resistivity of 1.0×1010Ω or more, the surface resistivity being measured according to JIS K6911with respect to the inside surface of the packaging container after moisture conditioned by being placed for 24 hours in a bath where the constant condition of 23 ° C. and 50% RH being set.
