摘要：
An ethylene-vinyl alcohol copolymer (EVOH) composition comprises 100 parts by weight of a powder (A) having a particle size of from 22 to 850 μm of an ethylene-vinyl alcohol copolymer (a) which has an ethylene content of from 2 to 60 mol % and has a degree of saponification greater than 95%, and from 0.0001 to 2 parts by weight of inorganic particles (B) having primary particles with a mean particle size of from 1 to 100 nm. The EVOH powder coating composition of the present invention forms a coating film having good uniformity when applied to a substrate as powder coating, even when it contains 1 part by weight or more water relative to 100 parts by weight of EVOH resin.
