Abstract
Ethylene-vinyl alcohol copolymer composition pellets comprise: an ethylene-vinyl alcohol copolymer; a boron compound; and a predetermined amount of at least one fisheye-suppressing component, wherein pellet surface portions of the ethylene-vinyl alcohol copolymer composition pellets have a boron compound content of not higher than 1.7 ppm on a boron basis based on the weight of the pellets. The ethylene-vinyl alcohol copolymer composition pellets are capable of suppressing occurrence of fisheyes even if being used for formation of a single-layer ethylene-vinyl alcohol copolymer film.
