A color printing production method and production device for corrugated plastic boxes

Abstract

The invention discloses a method for making color printing on corrugated plastic boxes. First, the printed color printing film and face paper are wound around the same hot roller, and the color printing film is heat-adhesively transferred to the face paper under the action of extrusion force. The surface paper with color printing is formed, and then the lining paper, corrugated paper and surface paper with color printing driven by the hot roller are sequentially transported to the forming hot roller synchronously from bottom to top, so that the lining paper, corrugated paper and color printing The surface papers are superimposed and bonded to form, and then sent to the cutting machine for cutting after cooling, so as to make a corrugated plastic box with color printing. The present invention can print various color printings on the corrugated plastic box. The color printing not only has clear printing effect, lifelike, clear layers, strong three-dimensional effect and good visual effect, but also the printing is firm and does not fade or fade. The method is simple, the labor intensity is low, the working environment is good, the operation is simple and easy to control, and the color printing of different sizes of layouts and the batch operation of corrugated plastic boxes of different sizes can be realized at the same time.

Description

technical field [0001] The invention relates to a method for making color-printed pictures and texts on packing boxes or boxes, in particular to a method and a production device for making color-printed pictures and texts on corrugated plastic boxes. Background technique [0002] With the continuous development of science and technology, color printing technology has fully replaced traditional manual or mechanical monochrome printing in paper packaging boxes (boxes), plastic flexible packaging, plastic woven packaging bags, glass plates, wood bamboo plates, metal sheets and porcelain plates. Printing not only greatly improves the effect of graphic and text color printing, but also simplifies the printing process, improves printing efficiency, reduces printing costs, and is conducive to environmental protection. As we all know, corrugated plastic board is a non-toxic, non-polluting, moisture-proof, fire-proof, light and firm, corrosion-resistant and impact-resistant sheet ma...

AI Technical Summary

Problems solved by technology

However, as one of the main packaging boxes in modern times, corrugated plastic boxes still use traditional manual or mechanical monochrome printing processes for graphics and text production due to the limitations of their corrugated plastic box structure and manufacturing process, such as screen printing. 1. Curved surface printing method, which not only has poor printing effect and unstable quality, but also has monotonous graphics and text colors, and low printing efficiency. At the same time, the printing operation is troublesome and the working environment is not good.
