Abstract:
The present invention relates to an ethylene-vinyl alcohol copolymer (EVOH) resin composition, an EVOH film formed therefrom, and a multilayer structure containing the same. The surface roughness of the EVOH resin composition is the peak material volume (Vmp) between 0.0008 and 10 μm3/μm2. The EVOH of the invention can reduce the torque output during processing, and can obtain the EVOH film with excellent appearance.
