Equipped with a high-precision heated slot die extrusion head and high-accuracy gear metering pumps. Delivers exceptionally uniform 100% solid adhesive coatings without air voids, streaking, or cross-web caliper deviations across 1700 mm wide webs.
Features dual high-efficiency mirror-polished internal chilled rollers connected to a high-flow industrial refrigeration unit. Instantly cools and sets the molten adhesive layer at line speeds up to 350 m/min, preventing thermal bleed-through and web deformation.
Maintains continuous closed-loop tension regulation across unwinding, hot adhesive application, chilling, and rewinding stations. Eliminates web wrinkles, stretching, and edge curling on sensitive PET films and extensible technical paper grades.
Integrates substrate unwinding, heated manifold feeding, coating, rapid chilling, and surface rewinding into an energy-efficient roll-to-roll workflow. Eliminates traditional drying tunnels and VOC exhaust systems, lowering factory emissions and energy consumption.

Turnkey Production Line Upgrades:
Note: Optional auxiliary hardware integrates directly into the centralized PLC touchscreen recipe control architecture.
A: Hot melt adhesive coating uses 100% solid polymers without volatile organic solvents or water. This eliminates long, energy-intensive drying ovens and complex VOC emission incinerators (RTOs), significantly reducing factory energy footprints and regulatory compliance costs.
A: Molten adhesives are applied at temperatures between 130°C and 180°C. The machine immediately passes the coated web over high-efficiency, water-chilled rollers with high wrap angles, freezing the adhesive layer within milliseconds before heat can penetrate and distort heat-sensitive thin-film substrates.
A: MEAREG engineers and manufactures complete hot melt coating lines in Guangdong. We supply comprehensive plant layout designs, hot-oil or electrical heating schematics, and complete Factory Acceptance Testing (FAT) with client substrates before seaworthy container shipping and global on-site commissioning.
