Ethylene-vinyl alcohol copolymer resin particle composition, ethylene-vinyl alcohol copolymer film formed therefrom, and multilayer structure |
abstract |
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 containing same. The EVOH resin particle composition comprises: a first EVOH resin particle, with the void volume (Vvv) of the valley of the surface being 0.00003-2 μm3/μm2; and a second EVOH resin particle, with the void volume (Vvv) of the valley of the surface being 0.00005-10 μm3/μm2. According to the present invention, the film thickness uniformity, oxygen penetration rate and stretchability of the EVOH resin particle composition can be improved. |
