Clear plastic packaging as a new form of packaging by consumers, more and more businesses began to use Clear Plastic Boxes as packaging products, especially in cosmetics, electronic appliances, sports equipment and other fields, Clear plastic packaging box application is particularly wide, and is growing at an annual 30% growth rate.

Widely used in Clear plastic packaging has also led to paste box gum market has undergone new changes, to the Clear plastic packaging hot melt gluing in the successful launch, but also for the development of Clear plastic packaging has played a catalytic role. In recent years, a variety of new hot melt adhesive series of products to the market, such as EVA hot melt adhesive, PUR hot melt adhesives. PUR hot melt adhesive is particularly good advantage to occupy a more important position in clear plastic boxes of gluing production, its market share is gradually rising. Below, I will combine the PUR hot melt adhesive developed by our company, to explore its application advantages and considerations in a clear plastic box gluing in, we hope to give people in the industry to bring some inspiration.

PUR hot melt adhesives and their advantages?

PUR hot melt adhesive, namely reactive polyurethane hot melt adhesive, the main component of polyurethane with -NCO groups of prepolymer. PUR hot melt reaction principle is: colloid by heating the coating on the substrate surface, will stick together after, PUR hot melt adhesive may be irreversible chemical reaction with moisture in the air after melting into a liquid two-layer substrate, forming polymers with high cohesion.

PUR hot melt adhesive has the following outstanding advantages: better stability. After a general hot melt adhesive is heated and melted into a liquid, when cooled to room temperature and then change back solid, and PUR hot melt adhesive is different, it will further react irreversibly to form a crosslinked substance. Use lower temperatures. Compared to ordinary hot-melt adhesives for, PUR hot melt adhesive may be at relatively low temperatures, so as to effectively prevent the clear plastic box gluing process heat distortion problems. Other performance advantages. PUR hot melt adhesives based on the reaction principle we can see, with the moisture in the air crosslinking reaction high cohesive strength of the polymer film formed, so PUR hot melt adhesives and hot melt adhesives compared to ordinary solvent resistance, anti-aging performance is very good, and excellent PUR hot melt adhesive paste manufactures low-temperature resistance and temperature resistance than ordinary hot melt adhesives.
