Beschreibung
Zusammenfassung:	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 meltmoldability. 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 resinand 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. 本发明提供可以抑制输送时的破裂、破损、微粉的产生、熔融成型性优异的乙烯-乙烯基酯共聚物皂化物粒料。本发明的乙烯-乙烯基酯系共聚物皂化物粒料为由包含乙烯-乙烯基酯系共聚物皂化物树脂的树脂组合物得到的粒料，利用球磨机的冲击粉碎试验后的微粉量相对于乙烯-乙烯基酯系共聚物皂化物粒料为400ppm以下。
