Abstract

A molding material comprising a pellet group of at least 20 saponified ethylene-vinyl ester-based copolymer pellets, wherein at least 95% of the pellets have a surface that is substantially a single closed surface, and when a maximum outer diameter of a pellet is taken as a long diameter and a minimum diameter in a cross section having the greatest area among the cross sections perpendicular to the long diameter is taken as a short diameter, the average value of the long diameter/short diameter ratio of at least 20 pellets taken from the pellet group is 1.6 or less and the standard deviation of the long diameter/short diameter ratio of the at least 20 pellets is 0.13 or less.
