LAMINATE SHEET FOR FOAMING, FOAMED LAMINATE SHEET, AND METHOD FOR MANUFACTURING FOAMED LAMINATE SHEET

摘要

PROBLEM TO BE SOLVED: To easily, promptly, and three-dimensionally form letters, figures, and various patterns on the surface of a laminate sheet. SOLUTION: In a foamed laminate film SA, a resin layer 2 is formed on one side of original paper 1. A pattern 3 of a gas-barrier varnish is formed on a surface opposite to the resin layer 2 fitted to the original paper 1 to make a laminate sheet for foaming. In addition, the laminate sheet for foaming is heated to expand a part of the resin layer 2 facing the pattern 3 to form an expanded part 5. COPYRIGHT: (C)2004,JPO
