Title:
METHOD FOR THREE-DIMENSIONALLY MOLDING FILM, METHOD FOR MANUFACTURING FILM MOLDED BODY, AND FILM MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2019/163305
Kind Code:
A1
Abstract:
Provided are a method for three-dimensionally molding a film, a method for manufacturing a film molded body, and a film molded body with which it is possible to easily apply three-dimensional molding to an inner film part while achieving a reduction of processing time and a decrease in energy consumption and without requiring a design change in existing equipment. The method for three-dimensionally molding a film comprises applying cold compression molding in a thickness direction to a film overlapped portion 50 in which at least one inner film part 20 having a first layer 21 and a second layer 22 having elasticity smaller than that of the first layer is arranged between two outer film parts 30 in a non-fixed state with respect to the outer film parts 30, thereby causing the inner film part 20 to protrude toward the second layer 22 side at the film overlapped portion 50.
