Gluing process for replacing adhesive film

Abstract

The invention belongs to the field of printing and packaging processes, particularly relates to a glazing process for replacing an adhesive film, and provides the following scheme aiming at the problems of poor wear resistance, scratch resistance, flexibility and waterproofness of the existing process, comprising the following steps: preparing materials to prepare plastic-replacing oil, wherein the material comprises a resin material, a special resin material, a water-based wax emulsion, silicon dioxide matting powder, a polymeric dispersant, a humectant, wear-resistant wax slurry H-859, an ethanolamine regulator, an auxiliary agent and a polyurethane polymer, and the special resin material comprises a hydroxyethyl acrylate copolymer and viscosity adjusting resin H-8905, and the gluing process for the plastic-replacing oil can replace a glue film. In addition, the effect close to that of a laminating process is achieved in the aspects of related physical properties and surface effects, presswork deplasticizing is achieved, the physical properties such as wear resistance, folding resistance and breakage resistance of the plastic-replacing glazing process reach the level close to that of the laminating process, and the product of the plastic-replacing glazing process can achieve the protection effects of moisture resistance, water resistance, chemical corrosion resistance and the like.

Description

technical field [0001] The invention relates to the technical field of packaging technology, in particular to a glazing technology for replacing adhesive films. Background technique [0002] The traditional lamination process needs to use lamination glue on the surface of the paper to coat and compound with PP / PET film, and then bond together with paper printed matter after heating and pressing to form a paper-plastic integrated product. The surface of the printed matter after lamination is smoother and brighter, and the film can also play the role of moisture-proof, waterproof, anti-fouling, wear-resistant, folding-resistant, chemical corrosion-resistant, etc., which can effectively protect the printed matter. For example, the application number is CN202010338780.6 The patent discloses a paper coating process. [0003] However, high molecular polymers such as PP / PET film used in the traditional film coating process are difficult to degrade in the natural environment, and i...

AI Technical Summary

Problems solved by technology

However, the current plastic replacement process has the following disadvantages: the physical properties such as folding resistance and burst resistance of the plastic replacement oil material are relatively inferior to those of high molecular polymers such as adhesive films; effect, it is necessary to prepare plastic replacement oil corresponding to the effect, so the material cost of plastic replacement oil is higher than that of the film coating process
