Industrial packaging requires long-term stable bonding performance, and permanent bonding hot melt glue provides reliable long-term adhesion for various packaging products. After complete curing, the adhesive forms a tough and stable bonding layer with strong aging resistance, avoiding natural degumming and cracking during long-term storage and transportation. It is suitable for industrial product outer packaging, heavy-duty carton sealing and long-term storage packaging. It resists daily temperature difference changes, dry and wet environment alternation, and maintains stable structural firmness of packaging boxes. Compared with ordinary adhesives with short service life, it reduces packaging replacement and rework costs, becoming the preferred durable adhesive solution for industrial batch packaging production.
