METHOD FOR MANUFACTURING MULTILAYERED FILM STRUCTURE, AND MULTILAYERED FILM STRUCTURE

摘要

PROBLEM TO BE SOLVED: To obtain a multilayered film structure having sufficiently assured strength in a join portion.;SOLUTION: The multilayered film structure 10 having the sufficiently assured strength in the join portion is obtained by arranging the end of one multilayered film 12 and the end of another multilayered film 12 face to face with a space placed between them, filling a molten welding thermoplastic material 24 into at least the space, welding the molten end of one multilayered film 12, the molten end of another multilayered film 12 and the molten welding thermoplastic material 24 to each other, cooling and solidifying them.;COPYRIGHT: (C)2011,JPO&INPIT
