Embodiment 1

[0031] A kind of inner layer printing laser composite paper manufacturing process is characterized in that, the steps are as follows:

[0032] (1) Corona treatment by transferring waste film:

[0033] The waste film remaining on other laser transfer products can absorb ink after corona treatment, and can be used as a composite film after printing;

[0034] Perform corona on the surface of the printed mask in advance: the temperature is 20°C, the corona resistivity is 10, r]ohm-cm dielectric strength is 16.9Kv / mm, and the surface tension of the printed surface of the film is increased to a value greater than 38 dyne;

[0035] At the same time, the ink factory is required to reduce the internal tension of the ink to ≤36 dynes, which can meet the printing tension requirements of 38 dynes on the film surface;

[0036] After adding the corona process, the waste film after the original transfer and stripping can be reused, which greatly saves the material cost.

Abstract

The invention discloses a novel inner-layer printing and laser composite paper manufacturing technology. A transferred waste film is subjected to corona pretreatment firstly, then film inner surface printing, film pressing and aluminizing are performed sequentially, and a backing paper product is composited. With the adoption of the technology, the production efficiency is improved greatly, the product cost is reduced, and the product competitiveness is enhanced. The technology has the advantages that the cost is greatly reduced, and problems about ink fastness and product scratching are solved.

Description

technical field [0001] The invention relates to a manufacturing process of inner-layer printed laser composite paper, which belongs to the field of printing. Background technique [0002] The inner layer printing laser composite paper technology project is mainly developed for high-end cosmetics and toothpaste outer packaging boxes. The ink production cost of the existing offset UV printing technology is high, and the post-printing process is easy to cause scratches on the product surface. [0003] The invention provides a process of corona pretreatment on the waste film after transfer, and then sequentially print on the inner surface of the film, film pressing, aluminizing, and composite bottom paper, which greatly improves the production efficiency and reduces the cost of the product. cost and enhance the competitiveness of products. The advantage of the invention is that the cost is greatly reduced, and at the same time, the problems of ink fastness and product scratche...
