Manufacturing process of three-layer one-way see-through film printing material

Abstract

The invention relates to a three-layer unidirectional perspective film printing material and a manufacturing method thereof. The film has a laminated structure with sequentially laminated layers of a PVC black and white film layer, a glue layer, and a bottom paper layer. The bottom paper layer is composed of double-spray single-silicon paper and hot-melt adhesive paper. Light-permeating through holes are regularly arranged on a vertical plane of the PVC black and white film, the glue, the double-spray single-silicon paper. A manufacturing process comprises the steps of hot-melt adhesive paper manufacturing, PVC black and white film back gluing and punching, and hot-melt adhesive paper laminating. With the process, hole shape and hole size of the unidirectional perspective film are not changed, and hole depth is increased. When the material is used in inkjet printing, ink absorption is excellent, pattern dimensional sense is increased, and pattern definition is increased, such that inkjet printing effect can be conveniently and more precisely evaluated. Also, raw material utilization rate is increased, and production cost is reduced; finished product flatness and rigidity are better.

Description

technical field [0001] The manufacturing process of the three-layer one-way see-through film printing material of the present invention relates to the technical field of advertisement display and decorative materials, especially the manufacturing process of the three-layer one-way see-through film printing material. Background technique [0002] One-way see-through film is a flat consumable material for advertising. It is currently mainly used to display advertising effects on automobile body glass, glass curtain walls, and shopping mall glass windows. At present, the general single-permeable film is mainly composed of PVC black and white film layer, glue layer and release paper layer. After hole making, the original release paper is removed and attached to the new release paper. There are the following technical problems in such a process: [0003] 1. There are also holes on the original backing paper after the hole is made, and the ink will leak through the small holes wh...

AI Technical Summary

Problems solved by technology

[0003] 1. There are also holes on the original backing paper after the hole is made, and the ink will leak through the small holes when printing, so the original backing paper must be replaced, and in order to make the finished product have good flatness and stiffness, the replaced new backing paper is generally thicker , the raw material utilization rate is low, and the cost is high;

[0004] 2. The small holes will be deformed during the peeling process of the original backing paper, which will affect the appearance;

[0005] 3. The new release paper to be replaced is white. The release surface cannot absorb the ink that leaks through the small holes during printing. The white background will damage the overall effect of the picture through the small holes, affecting the clarity of the picture, and cannot be accurately evaluated. Printing effect, making it difficult to control the accuracy of spray painting;

[0006] 4. PVC is easy to deform when hot-bonded, which affects the beauty of the pores;

[0007] 5. During the bonding process of the back glue, because dust and flying debris are easy to enter, it will affect the printing effect;

[0008] 6. The efficiency of thermal bonding is low, which affects production
