Roll-to-roll laminating machine

solvent-freeautomatedhigh-speed

Overview
Our solvent-less lamination machine bonds multi-layer flexible packaging materials using 100% solid (solvent-free) adhesives. Zero VOC emissions and 40–60% energy savings compared with solvent-based systems. Suitable for food, daily chemical, pharmaceutical and industrial packaging. Printing speed: 400 m/min. Loading/unloading: pneumatic tape winding + air expanding shaft. Compatible materials: BOPP, PE, PET, CPP, LDPE, NY, aluminum foil, paper and composite films. Solvent-free operation ensures no emissions and safe, environmentally compliant production.

Why Choose Solvent-less Lamination Technology?

• Environmental compliance: eliminates volatile organic compound (VOC) emissions and reduces regulatory risk.
• Lower operational costs: removes drying ovens, delivering 40–60% energy savings versus solvent-based lamination.
• Improved safety: no flammable solvent vapors, reducing fire hazards and related infrastructure needs.
• Food & pharmaceutical safety: solvent-less adhesives avoid residual solvent migration; designed to meet FDA 21 CFR 177.1390 requirements.

Key Technical Features

• Precision Coating System: Specialized 4-roll or 5-roll transfer mechanism with independent servo motors for each roller; applies very low coating weights (1.0–1.8 gsm). Metering rollers operate at controlled temperatures (40°C–50°C) to maintain optimal adhesive viscosity.
• Advanced Tension Control: High-sensitivity tapering tension control keeps total winding tension below 3 kg to prevent defects such as tunneling or telescoping and ensure proper roll formation.
• Automatic Mixing Unit: Two-component adhesive system (isocyanate + polyol) with automatic pumping to maintain precise mixing ratios (examples: 100:50 or 100:80). Requires flushing if production stops over ~30 minutes to prevent hardening.

Perfect Applications

• Food Packaging: Handles multi-layer barrier structures (e.g. BOPP//VMCPP, PET//PE) with lower processing temperatures to protect heat-sensitive films and eliminate chemical odors affecting product taste.
• Pharmaceutical & Medical: Suitable for sterile packaging structures (e.g. OPA//ALU//PVC), preventing chemical migration and ensuring product integrity.
• Heavy-Duty Industrial: Capable of bonding thick structures (e.g. PET//ALU//PE), supporting large-format bags (5kg–25kg) with high burst strength and moisture barrier performance.

Additional Information
Machine uses solvent-free adhesive chemistry that cures via chemical cross-linking; conditioned curing (24–48 hours at ~40°C) is required to achieve full bond strength. Recommended quality testing: universal tensile testing per ASTM D903 or ISO 11339 (measure Newton/15mm after full cure).
