Embodiment Construction

[0031] (Three-dimensional processing method and device thereof)

[0032] In the three-dimensional processing method of the present invention, the laminated film having at least an inner surface film with a relatively large elongation rate on the innermost surface and an outer surface film with a small elongation rate on the outer surface side along the laminated film by using the forming part The thickness direction of the film is compression-molded, so that after the pressure is released, three-dimensional processing is performed in such a way that the compression-molded part protrudes to the outer surface side. The molded portion is formed from a material having a large elastic deformation area with the largest elastic deformation area.

[0033] That is, the elastic deformation region of the formed portion is larger than the maximum elastic deformation region in the planar direction of the film constituting the laminated film, which means that the formed portion is larger th...

Abstract

Provided is a three-dimensional processing method in which a molding processing unit performs cold compression-molding on a laminated film in a thickness direction of the laminated film so as to project a compression-molded portion to an outer surface side, the laminated film having at least an inner surface film having a large elongation on an innermost surface and an outer surface film having asmall elongation on an outer surface side , the three-dimensional processing method being characterized in that the molding processing unit is made of a material which can achieve an elastic deformation area wider than the widest elastic deformation area in a plane direction of a film constituting the laminated film. According to the three-dimensional processing method of the present invention, aprojection portion having a wide working width can be formed in the compression-molded portion.

Description

technical field [0001] The present invention relates to a three-dimensional processing method of a laminated film, and more specifically, to a three-dimensional processing method capable of forming a wide protrusion on a laminated film and an apparatus therefor. Background technique [0002] For bag-shaped containers such as sachets used to fill semi-fluid or fluid contents such as food, beverages, and detergents, and seals used as lids for cup-shaped and tray-shaped containers, it is required to pass along with the product name and other characters. Various patterns are placed on them to differentiate from other companies' products and increase product value. In order to meet such demands, processing to make characters and patterns stand out, such as three-dimensional printing, has been performed. [0003] For example, Patent Document 1 below proposes a method for forming a bag-shaped container with an embossed pattern: using a flexible packaging material to form a bag-sha...
