摘要:
A composite deposited film including (A) a polymeric film substrate; (B) a deposit of an inorganic material formed on at least one side of the polymeric film substrate (A); and (C) a water-resistant film laminated on the deposit (B) and formed from a mixture containing polyvinyl alcohol and a polycarboxylic acid or a partially neutralized product thereof in a weight ratio of 95:5 to 10:90 is provided. A production process of a composite deposited film, which includes the steps of forming a deposit (B) of an inorganic material on at least one side of a polymeric film substrate (A); casting a solution of a mixture containing polyvinyl alcohol and a polycarboxylic acid or a partially neutralized product thereof in a weight ratio of 95:5 to 10:90 on the deposit (B); drying the mixture to form a film; and then subjecting the resultant dry film to a heat treatment at a temperature not lower than 100°C (373K), thereby forming a water-resistant film (C) on the deposit (B), is also provided.

Disclosed herein are a polyvinyl alcohol product obtained by heat-treating a melt-molded polyvinyl alcohol product composed of a polyvinyl alcohol composition containing 0.01 to 3.0 mmol of a metal compound based on 1 g of polyvinyl alcohol; a polyvinyl alcohol product obtained by stretching a melt-molded polyvinyl alcohol product composed of a polyvinyl alcohol composition containing 0.01 to 3.0 mmol of a metal compound based on 1 g of polyvinyl alcohol; and a multi-layer product comprising at least one inner layer of a melt-molded product composed of a polyvinyl alcohol composition containing 0.01 to 3.0 mmol of a metal compound based on 1 g of polyvinyl alcohol.
摘要:
Disclosed herein is a gas barrier film formed from a mixture containing polyvinyl alcohol and a partially neutralized product of poly(meth)acrylic acid in a weight ratio of 95:5 to 10:90, and having an oxygen permeability constant of 1.25 x 10- 3 ml(STP)·cm/m2· h·atm{Pa} or smaller as measured under conditions of 30°C and 80% relative humidity. A production process of the gas barrier film, in which a film formed from a mixture containing polyvinyl alcohol and a partially neutralized product of poly(meth)acrylic acid is subjected to a heat treatment under specific conditions, is also disclosed. The gas barrier film of the invention is excellent in water resistance and oxygen gas barrier property, free of any chlorine atom, and scarcely colored.
