MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF WRAPPING MATERIAL FOR ELECTRONIC COMPONENT CASE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a wrapping material for an electronic component case which can control equipment costs and achieve high production speed.

SOLUTION: The manufacturing method comprises a temporary bonding process of temporarily bonding the first sheet 1 made by laminating a thermoplastic resin layer 5 on one surface of a thermoplastic resin unstretched film layer 4 to the second sheet 2 made by laminating an aluminum foil layer 7 on one surface of a thermoplastic resin stretched film layer 6 to obtain a preliminary laminated sheet 3 by inserting the first sheet 1 and the second sheet 2 through a pair of rolls 12 and 13 in such a manner that the thermoplastic resin layer 5 comes in contact with the aluminum foil layer 7, heating and pressing them in the state that the thermoplastic resin is not molten; and a main bonding process of bonding the first sheet 1 and the second sheet 2 to integrate them into one body by heating the preliminary laminated sheet 3 and melting the thermoplastic resin.
