Comparative Analysis of Solvent-Free and Traditional Dry Lamination
In the flexible packaging industry, the choice of lamination process has always been a hot topic. Dry lamination is a mature technology that has long been the dominant process in China; solvent-free lamination, as a green technology, represents the future development direction.
Dimension 1: Environment and Solvent Residue
Dry lamination requires large amounts of organic solvents, posing VOCs emission and residue risks; solvent-free lamination uses no solvent at all, eliminating emissions and residue from the source.
Dimension 2: Energy Consumption and Cost
The oven drying step of dry lamination consumes high energy; solvent-free lamination needs no oven, greatly reducing operating energy and long-term adhesive and energy costs.
Dimension 3: Efficiency and Application
Dry lamination is highly compatible with high-solid adhesives and diverse structures; solvent-free lamination offers fast adhesive change and no glue bucket cleaning, suiting mass-standardized orders.
