Environmentally friendly, High efficiency will be the main trend of future packaging industries. In terms of composite adhesives, solvent-free adhesives will replace traditional solvent-based adhesives, which has become a consensus of the packaging industry. The solventless adhesive is more widely used in the flexible packaging industry.
Solvent-free adhesives are a viscous substrate, which can connect together by means of their viscosity. They are viscous liquid at normal temperatures, such as an epoxy resin which Is one of the most important auxiliary materials and has extremely wide applications in the packaging industry. Solvent-free adhesive mostly is adopted for the solventless laminating machine, also can be used on existing solvent drying compound equipment which is suitable for many color printing plants to improve the high residual solvent, reducing production costs, no need to input new equipment.
