Today in 2025, the production and circulation of goods are increasingly prosperous. Cartons, as the most common packaging form, play an indispensable role in various industries. During the process of carton packaging, heat-melt glue assumes a crucial role, serving as the key force that connects all parts of the carton.
The series of products including BL-8A3, BL-8A4, BL-3100, BL-3388H, BL-3388B, and BL-3388G play the following crucial roles during the process of transforming the cardboard from flat sheet material to the final shape:
First of all, the curing process is very fast. After the hot melt adhesive melts due to heating and comes into contact with the surface of the carton, it can be quickly cooled and cured within just a few seconds, achieving rapid bonding.
Secondly, due to factors such as strong adhesion, paper tension, and water absorption, traditional glue bonding processes often result in insufficient adhesion. However, hot melt glue has a strong adhesion to paper and can firmly bond all parts of the carton together.
Again, the weather resistance is strong. During transportation and storage, the cardboard box will encounter different temperature and humidity environments. Therefore, the pressure-sensitive hot melt adhesive blocks need to have good temperature resistance and moisture resistance. They should not soften or flow at high temperatures, and should not become brittle or lose adhesion at low temperatures. They should also maintain good bonding performance in humid environments.
Finally, it is environmentally friendly and cost-effective. With the increasing awareness of environmental protection, it is necessary to choose hot melt adhesives that meet environmental standards and do not contain harmful substances. At the same time, costs should be reasonably controlled. Under the premise of ensuring quality, products with good cost performance should be selected.
