Title:
SHEET MATERIAL AND DIFFERENTIAL PRESSURE MOLDING CONTAINER
Document Type and Number:
Japanese Patent JP2019171727
Kind Code:
A
Abstract:
To provide a sheet material and a differential pressure molding container which can suppress accidental occurrences of joining which is not intended while lowering rigidity of the sheet.SOLUTION: A sheet material used for a differential pressure molding container comprises: a first resin layer to secure sheet strength; and a second resin layer that forms one side of the sheet material, the tensile modulus of elasticity is lower than that of the first resin layer, and used for joining by heat seal. A bondable temperature at which the joining of the second resin layer by heat seal is enabled is higher than a moldable temperature at which differential pressure molding of the first resin layer is enabled.SELECTED DRAWING: Figure 1
