Abstract
Ethylene-vinyl alcohol copolymer composition pellets comprise: an ethylene-vinyl alcohol copolymer, a conjugated polyene, 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 conjugated polyene content of not lower than 30 ppb based on the weight of the pellets. Such ethylene-vinyl alcohol copolymer composition pellets are capable of reliably suppressing occurrence of minute fisheyes having a diameter of 200 μm or smaller.
