Solvent-free or solventless adhesives are viscous substance, which can be connect various substrates together by means of their viscosity.
They are viscous liquid at normal temperatures, such as polyurethane which is one of the most important materials and has extremely wide applied in the packaging industry. The composite film adhesive for flexible packaging is constantly getting improvement and innovation on the technical. The new type of solventless adhesive performance can completely meet the dry composite requirements among the most flexible packaging materials.
Besides High efficiency and fast running, environmental friendly will be the main trend of future flexible packaging lamination. In terms of composite film adhesives, solvent-free adhesives will replace conventional solvent-based adhesives, which has become a common sense in the flexible packaging industries. The solventless or solvent-free adhesive is more widely used in the flexible packaging lamination.
