Ethylene-vinyl alcohol copolymer resin particle composition, ethylene-vinyl alcohol copolymer film formed therefrom, and multilayer structure

The present invention relates to an ethylene-vinyl alcohol copolymer (EVOH) resin particle composition, an ethylene-vinyl alcohol copolymer film formed therefrom, and a multilayer structure comprising the same. The EVOH resin particle composition includes a first EVOH resin particle having a surface peak solid volume (Vmp) of 0.00001 to 6 [mu] m < 3 >/[mu] m < 2 >; and second EVOH resin particles having a surface peak solid volume (Vmp) of 0.00015 to 20 [mu] m < 3 >/[mu] m < 2 >. The processing performance and the mechanical property of the EVOH composition can be improved when the EVOH composition is prepared into a film. 本发明是关于一种乙烯-乙烯醇共聚物(EVOH)树脂颗粒组合物、由其形成的乙烯-乙烯醇共聚物膜及包含其的多层结构。该EVOH树脂颗粒组合物包括第一EVOH树脂颗粒，其具有一表面波峰部实体体积(Vmp)为0.00001～6um3/um2；以及第二EVOH树脂颗粒，具有表面波峰部实体体积(Vmp)为0.00015～20um3/um2。本发明可改善EVOH组合物制成薄膜时的加工性能及机械特性。
