A solventless laminating machine is a piece of equipment used in the flexible packaging industry to bond two or more substrates together (like film to film or film to aluminum foil) without the use of chemical solvents.
Unlike traditional solvent-based or water-based laminators that require drying ovens to evaporate carriers, Sinstar’s solventless machines use adhesives in their pure form. The adhesive is applied directly to the substrate, and the substrates are married together using precision pressure rollers. Because there are no solvents, there are no emissions and no need for long drying tunnels. This makes the process significantly more energy-efficient and environmentally friendly. Sinstar’s technology focuses on precision mixing and application to ensure strong bond strengths despite the absence of solvents.
