PROCESS FOR FORMING FILM OF HYDROLYZED ETHYLENE-VINYL ACETATE COPOLYMER

摘要

A process for forming a film of a hydrolyzed ethylene-vinyl acetate copolymer which comprises: coating a solution comprising a hydrolyzed ethylene-vinyl acetate copolymer to a substrate, drying the wet film and subjecting the dried film to heat-treatment, said obtained film being formed so as to have a ratio of absorbance at 1140 cm-1 to absorbance at 1090 cm-1 in infrared absorption spectrum of not less than 0.65. According to the process of the present invention, the hydrolyzed ethylene-vinyl acetate copolymer film having excellent oxygen impermeability can be obtained.
