Henkel Loctite Liofol LA 7837/LA 6265 solvent-free adhesive system for packaging

Henkel Adhesive Technologies is launching Loctite Liofol LA 7837/LA 6265, a solvent-free, aliphatic adhesive system that is tailored for applications involving high thermal stresses — in particular retort packaging for pet food, for example. The technology is suitable for PET/Alu/CPP packaging as well as modern polyolefin structures.

Features include ultralow monomer content (<0.1%), the complete absence of epoxy silane, high temperature resistance of up to 134°C, and a low application weight enabling high production efficiency. In addition, the energy-intensive drying step is rendered obsolete due to the system being solvent-free. The product enables curing at room temperature, which helps to reduce material and energy consumption.

The system is focused on safe processing even at high machine speeds and under varying conditions. In addition to retort packaging in the pet food industry, other applications include ready meals, microwave products and pharmaceutical packaging.
