The application of packaging hot melt adhesive

It is very important to understand the extensive application of adhesives in the packaging industry, including the formation and sealing of boxes, paper bags, cartons, labels, special applications, etc. All these applications share a common priority: ensuring the stability, safety and storability of packaged products, which helps to ensure that they do not yield to weight or temperature during transportation.

For instance, due to increasingly strict global food safety policies, the food industry should be regarded as one of the most stringent and challenging packaging markets. The quality of packaging hot melt adhesive is crucial for meeting the safety, stability and hygiene standards of this market. Hot melt adhesives used for these applications must have high adhesion to difficult-to-treat substrates, low viscosity, resistance to extreme temperatures, and almost no odor.

Hot melt adhesive producers must also respond to the efforts made by the packaging industry to improve the appearance and brand of packaging. For this reason, a series of new hot melt adhesives containing high polymers have recently been launched to the market. These industrial hot melt adhesives feature high thermal stability and a faint odor, as well as low density and improved bonding performance, thereby increasing their output.

An increase in the amount of polymer added to hot melt adhesive can reduce the percentage of resin in the hot melt adhesive, thereby generating a more stable solution. These hot melt adhesives offer improved performance and help enhance the final appearance of the packaging.

Therefore, the hot melt adhesive industry has extensive requirements to meet the constantly evolving needs of the packaging industry. Three core features: good adhesion, versatility on various substrates, and excellent cold and heat resistance. The higher the adhesive force and thermal stability, the lower the consumption of hot melt adhesive. This brings two significant advantages: safer and more stable products; And reduce the use of hot melt adhesive, thereby having a positive impact on the environment.
