Printing technology for environment-friendly carton

Abstract

The invention discloses a printing technology for an environment-friendly carton. The printing technology includes the following steps of 1) platemaking; 2) plate surface cleaning; 3) dust removing; 4) disinfecting; 5) printing ink spraying; 6) odor adsorbing; 7) drying; 8) air-cooling temperature reduction; 9) bundling; 10) warehouse storage. According to the carton printing technology, equipmentused in an original disinfecting link is changed into ultraviolet-ray illumination disinfecting equipment, and compared with a common treating method for disinfecting a carton with a chemical disinfection reagent, through the ultraviolet-ray disinfecting method, the disinfecting efficiency and quality of the carton surface are improved, the cost required in the carton disinfecting link is reduced, and the printing technology is suitable for small and medium-sized enterprises; in addition, an activated carbon adsorption equipment is additionally arranged in the carton printing technology, andthe pungent smell in the carton and printing and dyeing ink can be adsorbed.

Description

technical field [0001] The invention relates to the technical field of carton printing, in particular to a printing process for environmentally friendly cartons. Background technique [0002] Carton is the most widely used packaging product. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Cartons are commonly used with three layers and five layers. Seven layers are rarely used. Each layer is divided into Lining paper, corrugated paper, core paper, surface paper, lining and surface paper include tea board paper, kraft paper, core paper uses corrugated paper, the color and feel of various papers are different, and the paper (color, feel) produced by different manufacturers is also different. Similarly, in the process of carton processing, in order to improve the aesthetics or recognition of the carton, it is necessary to print on the surface of the carton. [0003] After searching, the...

AI Technical Summary

Problems solved by technology

[0005] To sum up, in the technical content of the above two patents and the carton printing process in the prior art, there are disinfection steps. However, the disinfection steps in the above two patents and the prior art all use chemical disinfection reagents to treat the surface of the carton. Disinfection, the defect of this disinfection method is: since the chemical disinfection reagent itself is in a liquid state, when it is sprayed on the surface of the carton, a first-level drying equipment must be added in the subsequent process, the purpose is to dry and evaporate the chemical disinfection reagent Only after treatment can the subsequent printing process be carried out. This disinfection method increases a large amount of printing costs and brings unnecessary economic losses to the manufacturer; in addition, in the prior art, the components of the carton and the ink contain harmful The pungent smell, which is not adsorbed in the process, causes the carton to have a certain amount of pungent smell when it leaves the factory, which will affect the health of users
