Title:
封止フィルムの製造方法および封止フィルム
Document Type and Number:
Japanese Patent JP5659241
Kind Code:
B2
Abstract:
A process for producing a sealing film (1) to be interposed between each electrode (11), as a power-generating element, that has been introduced into a bag (20) and the edge of the bag (20), the process comprising: a melt kneading step in which both an acid-modified polyolefin resin A to which a carboxylic acid has been grafted and a resin B having functional groups capable of reacting with the carboxy groups of the resin A are melted and kneaded together to thereby chemically bond the carboxy groups of the resin A to the functional groups of the resin B and convert the resins into a resin C; a heat-resistant-layer formation step in which the resin C is formed into a layer to form a heat-resistant layer (3); an adhesive-layer formation step in which a carboxylic-acid-modified polyolefin resin D is formed into a layer to form an electrode adhesion layer (2) which adheres to electrodes; and a laminating step in which the heat-resistant layer (3) and the electrode adhesion layer (2) are directly laminated to each other when the resin C and/or the resin D is in a molten state.
