An ethylene-vinyl alcohol copolymer resin composition pellet group is provided, which is excellent in long-run processability. The ethylene-vinyl alcohol copolymer resin composition pellet group is a group of pellets of an ethylene-vinyl alcohol copolymer resin composition containing an ethylene-vinyl alcohol copolymer and a divalent metal salt, wherein not greater than 3% of the pellets have a b*-value of not less than 5 after the pellets are heat-treated at 230&#xb0; C. for 30 minutes.

Group of pellets of ethylene-vinyl alcohol copolymer resin composition

The invention provides a saponified ethylene-vinyl ester copolymer pellet which can be inhibited from cracking, chipping and generation of fine powder at the time of transport and is excellent in melt moldability. The saponified ethylene-vinyl ester copolymer pellet of the invention is a pellet which is obtained from a resin composition containing a saponified ethylene-vinyl ester copolymer resin and in which an amount of fine powder after an impact crushing test with ball mill is 400 ppm or less with respect to the saponified ethylene-vinyl ester copolymer pellet.
