Problems solved by technology

Commonly used plastics such as PP / PE have caused a lot of pollution to the environment because of the title of "immortality". These plastics can exist underground for hundreds of years without degradation, affecting land quality and plant growth.
[0003] Packaging film is a commonly used surface treatment method at present, and most of them use BOPP film. Since the packaging paper is completely biodegradable, it is difficult to separate the film and paper after film covering, which affects the recycling of packaging paper, resulting in The recycling rate of film-coated packaging paper has dropped severely, so it is necessary to develop an environmentally friendly method that does not affect the recycling of packaging paper to replace the existing film-coating scheme

Embodiment 1

[0033] A printing oil that can replace the dummy film for packaging, including printing oil, the printing oil includes a folding-resistant base oil and a wear-resistant surface oil. In traditional lamination, it is difficult to take into account both wear resistance and folding resistance. In most cases , the better the wear resistance, the worse the folding resistance. The anti-folding primer is coated on the product surface, and the surface of the anti-folding primer is coated with a layer of wear-resistant surface oil. The content is 42%, showing weak alkaline. The color of the anti-folding base oil is milky white, the viscosity is 80±15s after coating four cups, the solid content is 42%, and it is weakly alkaline. The folding-resistant primer is used to make the finished product to achieve the purpose of folding resistance, and then apply a layer of wear-resistant primer to achieve the purpose of wear-resistant. The amount of wear-resistant surface oil should be paid spec...

Embodiment 2

[0036] A printing process that can replace a packaging dummy film, comprising the following production steps:

[0037] Step 1: The printing machine prints the graphic and text content, and applies the anti-folding primer on the line. The anilox roller is 80 lines, and the coating amount is 14cm. 3 / m 2 , the printing speed is 8000pcs / h, infrared drying, and then natural drying for 24h;

[0038] Step 2: Apply the wear-resistant surface oil to the flatbed machine. Since the oiled roller is a rubber roller, the thickness of the oiled oil needs to be adjusted. In order to ensure its folding resistance, the oiled amount is guaranteed to be 26cm. 3 / m 2 , in which infrared drying is performed first;

Abstract

The invention discloses printing oil capable of replacing a packaging matt film, which comprises printing oil, and the printing oil comprises folding-resistant bottom oil and wear-resistant surface oil, the folding-resistant bottom oil is coated on the surface of a product, a layer of wear-resistant surface oil is coated on the surface of the folding-resistant bottom oil, the folding-resistant bottom oil is used for enabling the finished product to achieve the folding-resistant purpose, and then a layer of wear-resistant bottom oil is coated to achieve the wear-resistant purpose; compared with the prior art, the surface treatment technology replaces a film covering technology, the surface treatment cost is reduced relative to the film covering cost, recycling after packaging boxes are discarded is facilitated, the recycling income is increased, the call of the environment-friendly plastic removing policy is responded, and the enterprise competitiveness is improved.

Description

technical field [0001] The patent of the present invention relates to the field of packaging and printing, in particular to the surface treatment process of packaging. Background technique [0002] At present, the pace of plastic removal is being stepped up at home and abroad, especially some of the world's top 500 companies have pointed out that they should complete the strategic requirements of all plastic removal by 2030. White pollution has caused catastrophic damage to our planet, and experts have even detected the composition of microplastics in animals. Commonly used plastics such as PP / PE have caused a lot of pollution to the environment because of the title of "unchangeable through the ages". These plastics can exist underground for hundreds of years without degrading, which affects the quality of the land and the growth of plants. [0003] Packaging film is a commonly used surface treatment method at present, and most of them use BOPP film. Since the packaging pap...
