Title:
LAMINATED WELDED FILM BODY, ULTRASONIC WELDING MACHINE, METHOD OF MANUFACTURING LAMINATED WELDED FILM BODY
Document Type and Number:
Japanese Patent JP2022150351
Kind Code:
A
Abstract:
To provide a laminated welded film body in which bags are welded to each other and airtightness of the bags is ensured.SOLUTION: In a laminated welded film body 1, a second protective layer 14 of a first film base 2 and a third protective layer 22 of a second film base 3 are welded and fixed by an adhesive layer eluted from at least one of a first adhesive layer 11 to a fourth adhesive layer 27 through a first melt-through 6a of the second protective layer 14 and/or a second melt-through 6b of the third protective layer 22. A welded and fixed welded and fixed part 6c is surrounded in plane view by a first welded part 33 where the first adhesive layer 11 and the second adhesive layer 15 of the first film base 2 are welded together and/or a second welded part 35 where the third adhesive layer 23 and the fourth adhesive layer 27 of the second film base 3 are welded together.SELECTED DRAWING: Figure 6
