ABSTRACT:
A process for forming a film of hydrolyzed ethylene-vinyl acetate copolymer employing a mixed solvent of water, at least one member selected from the group consisting of propyl alcohol, butyl alcohol and benzyl alcohol, and at least one member selected from the group consisting of formic acid, an alkyl formate, acetic actid, an alkyl acetate, dimethylsulfoxide and N-methylpyrrolidone as a solvent for the copolymer.
A process includes an applying operation which can be carried out at normal temperature employing a solution in a low concentration of the copolymer.
Also, a process need not any additional operation or special devices to form an even and homogeneous film of the hydrolyzed ethylene-vinyl acetate copolymer having excellent properties such as transparency and gas impermeability suitable for wrapping or packaging material.
