Gluexpert Single-Component PUR Platen-Melt Adhesive Machine for Solvent-Free Paper/Plastic & Paper/Aluminium Lamination — Working Principle

Save 33%–50% on adhesive! Gluexpert's single-component PUR platen-melt technology — a new solvent-free lamination solution!

Flexible packaging plant owners, are you still troubled by PUR hot-melt adhesive aging from prolonged heating, carbon buildup at the bottom of the drum clogging the pipes, and persistently high lamination costs? Traditional melting heats the entire drum continuously, so the adhesive is repeatedly overheated and degrades — causing white spots, delamination and gun clogging, plus material waste and downtime for maintenance. Every one of these is eating into your plant's profits.

✅ Gluexpert's single-component PUR adhesive machine — a platen-style "melt-on-demand" solution that directly tackles these industry pain points.

Core Working Principle

Gluexpert's solvent-free two-component adhesive mixer is equipped with a PLC intelligent control system and uses precision gear pumps to draw the adhesive main agent and curing agent separately. It achieves accurate metering at the set ratio (100:50, 100:100, etc.); the adhesive is then conveyed through heated, insulated hoses to a static mixing tube for thorough, uniform blending, and the mixed adhesive is continuously delivered to the coater unit of the laminator.
The whole machine integrates real-time monitoring of temperature, pressure and flow with full-process data tracking, keeping the mixing process stable and controllable, reducing adhesive waste and lowering the defective rate.

💡 Seven Core Advantages to Boost Efficiency and Cut Costs on Your Lamination Line

  1. Compatible with solvent-free laminators, expanding into paper-plastic / paper-aluminium laminationAdd one Gluexpert single-component PUR adhesive machine and you can run solvent-free paper/plastic and paper/aluminium lamination. It can be integrated online with solvent-free laminators of all brands, so upgrading older equipment requires no full-line replacement.
  2. Greatly lower adhesive cost — save 33%–50%Compared with the traditional dry-lamination process, overall adhesive cost drops by 33%–50%. Over long production runs, every bit saved is real profit.
  3. Fast heating, uniform and stable meltingReaches 100°C in just 10 minutes. The combined platen + flow-channel design distributes heat evenly for stable output, shortening startup wait time and raising line utilization.
  4. High coating precision, strong product consistencyCoating weight is monitored in real time with deviation ≤0.2 g/m², ensuring even thin coating and stable finished appearance while reducing defect rate.
  5. Double-layer sealing structure locks in adhesive performanceThe double-seal ring design delivers excellent sealing, isolates moisture and protects the PUR adhesive from premature moisture absorption and failure, extending its service life.
  6. Multiple safety protections for worry-free productionReal-time pipeline pressure monitoring + over-pressure protection, combined with precise, stable temperature control and automatic fault protection, reduce the risk of pipe burst and high-temperature failures — simple and safe to operate.
  7. Versatile across industries, adaptable to diverse lamination scenariosWidely used in flexible packaging solvent-free lamination, textile fabric lamination, automotive interior bonding, home-appliance assembly and more — one machine, many uses. Run it inline without major modifications to existing equipment, lowering implementation cost.

🎯Ideal for these flexible packaging manufacturers

✔ Flexible packaging plants looking to upgrade to solvent-free lamination for paper-plastic and paper-aluminium products ✔ Those plagued by PUR adhesive carbonization, pipe clogging, lamination delamination and high defect rates ✔ Those wanting to cut adhesive cost and upgrade or retrofit existing solvent-free equipment ✔ Textile, automotive and home-appliance producers running single-component PUR bonding processes

The competition in the flexible packaging industry is intensifying; cost reduction plus stable quality is the core competitiveness. Gluexpert's single-component PUR platen-melt adhesive machine melts on demand, rejects adhesive carbonization, and delivers high-precision stable coating — helping plants easily adopt the new solvent-free lamination process.
