A solid adhesive that does not require solvents, does not contain water, and has 100% solubility at room temperature. When heated and melted to a certain extent, it becomes a liquid adhesive that can move and has a certain viscosity. After melting, it becomes a light brown semi transparent or naturally white color. The main component, which is the basic resin, is the copolymerization of ethylene and vinyl acetate under high pressure, and is then mixed with viscosity enhancers, viscosity regulators, anti oxidants, etc. to make a hot melt adhesive. 【】 is a plastic adhesive that changes its physical condition with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Hot melt adhesive bonding is the process of using a hot melt adhesive machine to melt the hot melt adhesive through heat. The melted adhesive becomes a liquid and is sent to the surface of the object being bonded through the hot melt adhesive tube and gun of the hot melt adhesive machine. After cooling, the hot melt adhesive completes the bonding process. It can meet the various requirements of cardboard box sealing and overcome the shortcomings of previous cardboard box sealing methods. To fully leverage the advantages of hot melt adhesive in cardboard box sealing, match it with a high-quality and reliable hot melt adhesive machine with corresponding quality and functionality. In terms of hot melt adhesive equipment, when selecting a hot melt adhesive machine, cost and power should be comprehensively considered. Based on speed requirements, packaging box shape and sealing method, production site, suitable layout of hot melt adhesive equipment and pipes, nozzles, and supporting auxiliary equipment, to achieve automated or semi-automatic adhesive spraying, and to leverage the advantages of hot melt adhesive to achieve significant results and economic benefits. In this regard, you can consult with the manufacturer of the hot melt adhesive machine. Overall, choosing a fully automatic or semi-automatic spraying method greatly leverages the speed and cost advantages of hot melt adhesive in box sealing compared to manual methods.
