Solvent less Laminating Machine is a product researched and developed by our company combined with the gradually matured solvent-free laminating technology. It’s based on the characteristics of the solvent-free laminating process itself. In order to solve such key problems, many targeted innovations have been carried out in our machine including the mechanical structure, control methods, safety protection and appearance design. It is suitable for high-speed lamination of different types of films, paper and aluminium foils. It has the advantages of high efficiency, good performance and solvent residue-free.

To manufacture flexible packaging in the most sustainable manner possible, one can utilize solvent-free adhesive lamination technology, also known as solvent less lamination. The laminating adhesive used in this process is two-component polyurethane. These two components must be mixed together in the appropriate way to form a useful adhesive that will bond the material layers to each other, forming a flexible packaging substrate.
