Dualam Solventless Laminating Machine
Solventless Lamination Machine
This solventless laminating system features dual coating units and was developed through a collaboration that combines over 17 years of lamination engineering experience with more than three decades of adhesive formulation expertise. Launched in 2023, our laminating equipment offers precise control, stable performance, and enhanced flexibility for multi-layer flexible packaging.
- Max laminating speed: 300m/min
- Max web width: 1050/1300mm
- Max unwinding diameter: 800mm
- Max rewinding diameter: 1000mm
- Inner diameter of core: 3'' or 6''
The solventless laminating machine is equipped with two independent coating units: a five-roller transfer coating system and a closed-chamber gravure unit. A- and B-component adhesives are applied separately to each substrate before lamination and rewinding. Compared to conventional solventless laminating systems, this dual-coating approach offers several significant advantages:
- No mixing unit is required, eliminating the risks associated with improper mixer cleaning or maintenance
- Curing time is significantly reduced, laminates can move on to slitting or pouch conversion in as little as six hours, helping shorten delivery timelines
- The adhesive's long open time allows for easier job changeovers without needing to clean the coating units between runs
- Fewer bubbles are produced during the adhesive reaction, resulting in improved visual quality, especially important for high-barrier film structures
- Supports curing at room temperature (20–25°C), reducing both energy consumption and carbon emissions
