HENKEL: GLYMO-Free Adhesive Solution for Packaging
The base Loctite Liofol LA 2798 adhesive can be combined with different hardeners for specific areas of application.
Henkel recently introduced Loctite Liofol LA 2798, a formulation that was reportedly specifically developed for high-performance packaging applications such as thermal processes like sterilization. It is completely free of (3-glycidyloxypropyl)trimethoxysilane (GLYMO), epoxy silane, and heavy metals. Loctite Liofol LA 2798 has been designed as a modular system. The base component can be combined with different hardeners for specific areas of application: sterilization processes, aggressive filling goods, and hot filling processes. The fields of application range from pet food and medical applications to convenience products.
“Common flexible packaging adhesives in the high-performance segment may still rely on GLYMO as an adhesion promoter,” said Helga Garmann, manager of product development for Polyurethanes Europe. “Henkel, however, has always attached the highest importance to offering clean and uncritical formulations.”
