Waterproof cardboard and corrugated box gluing
Intercol has several solutions for waterproof adhesives for bonding cardboard boxes. These boxes are usually made of laminated PE or PE-coated cardboard (Cardboard and corrugated). Technologies used include hot melts and dispersion (water-based synthetic adhesives). These adhesives are also used in food packaging (end-of-line) and in the production of packaging (such as printers). In addition to the designated food safety (use of adhesives and coatings for food packaging). The adhesives are therefore also well suited for the use inverpakkingen of various other products, such as crops and flowers.
Naturally, there are several challenges to look to find the right glue connection, in addition to the durability requirements, there will also be asked for a certain degree of production efficiency. A hotmelt is in principle well suited because of its good adhesion to plastic materials such as PE, the filling property (the filling of cracks and seams), and the speed of processing (due to the rapid cooling from ambient temperature to 160 degrees after a few seconds, further products are again transporting). Hot melts know the fastest packing lines a pressing time (cooling time, setting time, "drying") of approximately 0.1 seconds. Depending on the amount of hot melt, the construction of the package and the used packaging materials (plastic, standard carton, test liner, kraft liner, PE, PP or metalized).

Naturally, waterproof cardboard boxes are glued with water-resistant adhesives, which can meet standard water resistance test or specific watervastheids-testing.
