Title:
GAS BARRIER FILM
Document Type and Number:
Japanese Patent JP2019093692
Kind Code:
A
Abstract:
To provide a gas barrier film that is difficult to cause deterioration in gas barrier properties even by bending and traction resulting from bending.SOLUTION: In a gas barrier film 10 constituted by laminating a gas barrier coating layer 13 on a base material film 11, the gas barrier coating layer has microfibrillated celluloses blended therein. The microfibrillated celluloses form a network structure in the gas barrier coating layer and exhibits high gas barrier properties by a hydrogen bond or a strong interaction due to crosslinking between the microfibrillated celluloses. In addition, as the gas barrier coating layer having microfibrillated celluloses blended therein has high flexibility, it is difficult to cause deterioration in gas barrier properties by bending and traction resulting from bending.SELECTED DRAWING: Figure 1
