Preparation method for medium-free printing air bubble film

Abstract

The invention belongs to the technical field of air bubble film preparation, and particularly relates to a preparation method for a medium-free printing air bubble film. The preparation method is implemented in a medium-free printing air bubble film production device, and the production technology process of the preparation method comprises the following steps of (1) device startup; (2) material heating; (3) material forming; (4) printing; (5) ink drying; and (6) winding. In the process of producing an air bubble film, characters or patterns are printed directly on the surface of a flat film layer of the air bubble film, and a medium layer, a printing medium layer, and a thermal bonding or bonding medium layer do not need to be produced in advance; an air bubble cannot be compressed and damaged in the printing process of the preparation method, so that the air bubble film with the printing layer is produced and formed at a time, and the printing layer is firm and clear in adhesion; andthe preparation method has the advantages that the production technology is simple, the production device is advanced, the production efficiency is high, the resources are saved, and the applicationenvironment is friendly.

Description

Technical field: [0001] The invention relates to the technical field of bubble film preparation, in particular to a method for preparing a medium-free printed bubble film, which uses medium-free printing bubble film production equipment to directly print on the bubble film in a medium-free mode. Background technique: [0002] Now the express delivery industry is developing very rapidly. Almost everyone likes to buy things online. After our things are mailed, they are usually wrapped with bubble film to prevent them from being damaged during transportation. Because of the bubble film Lightweight, waterproof and drop-proof, it is the first choice for wrapping materials; the existing bubble film is generally a double-layer single-sided bubble film (one side is a bubble layer, and the other side is a flat film layer). This kind of bubble film is a light texture, Good transparency, non-toxic and tasteless plastic packaging materials, double-layer single-sided bubble film is curre...

Problems solved by technology

For example, Chinese patent 201010207776.2 discloses a bubble film forming device. The bubble roller and the rubber roller are arranged side by side in parallel. The end surface of the bubble roller is connected with a vacuum tube, and the end surface of the rubber roller is connected with a cooling water pipe. Printing film roll, when applied, the printed PE film strips are directly thermally compounded on the bubble film when the bubble is formed; Chinese patent 201721028101.5 discloses a bubble packaging bag, and the flat transparent printing film is fixed on the bubble film bag body On the surface, the transparent printing film is easy to print fonts, and the printed fonts are relatively clear, and it is easy to clearly print the recycling logo on the surface of the bubble film bag; these existing technologies have high production input costs, large material consumption, and waste of resources. Disadvantages: At present, there is no need to print the medium layer, and there is no medium mode printing directly on the surface of the air bubble film, and the printing effect is good.
