Industrial Roll-to-Roll Lamination Machine Line
Engineered to resolve web wrinkling, high solvent VOC hazards, and delamination failures in barrier packaging, OYANG's industrial lamination machine series synchronizes continuous high-velocity converting across thin films, foils, and nonwovens. Our multi-technology lineup incorporates the adhesive-free extrusion lamination machine for hot-melt PE/PP resin coating on nonwoven bags, the flagship solvent free lamination machine (ONL-LA450) reaching 500 m/min with zero solvent odor and 0.8–2.5 g/m² precision PU metering, and the heavy-duty dry laminating machine (ON-DL-3125F) with multi-zone ovens for aggressive retort pouch complexes.
Three Technologies, One Complete Lamination Portfolio
From solvent-free polyurethane bonding to direct polymer extrusion and solvent-based thermal drying, OYANG covers all flexible converting requirements.
Extrusion Lamination Machine — ONL-M Series
Molten PE or PP resin extruded directly onto nonwoven web or paper substrates. Requires zero adhesive and no drying oven. Engineered as an upstream barrier solution for high-speed nonwoven box bag lines.
Solvent Free Lamination Machine — ONL-LA450
Two-component reactive PU adhesive curing at ambient temperature — zero VOC emissions, no drying tunnel. Features Italian Mizar dynamic mixing, 10 servo-driven axes, and 5-roll precision metering up to 500 m/min.
Dry Laminating Machine — ON-DL-3125F
Thermal-activated adhesive bonding for multi-layer flexible film complexes. Runs up to 450 m/min with 1050–1300 mm web widths. Superior barrier performance for retort pouches, aluminum foil, and pharma packaging.

Web Converting Mechanics — All Three Technologies
Analyze how polymer melts, reactive polyurethanes, and thermal carriers interact across precision nip roller gaps.
Extrusion Polymer Bonding Mechanism
Pelletized PE or PP resins are melted in an electrically heated extruder barrel and forced through a high-precision T-die slit at temperatures ranging from 280°C to 315°C. The molten polymer curtain directly contacts the moving substrate at the chill-roll nip, crystallizing instantly to form a high-integrity barrier without intermediate adhesives.
Reactive Polyurethane 5-Roll Metering
Two-component liquid polyurethane adhesive (Isocyanate and Polyol) is continuously metered via Italian Mizar dynamic systems. The five-roll precision transfer unit creates an ultra-thin adhesive film (0.8–2.5 g/m²) transferred onto the primary web prior to ambient compression bonding.
Gravure Coating & Multi-Zone Thermal Desolvation
Adhesive dissolved in solvent or water is gravure-coated onto the web at higher coat weights (1–5 g/m²). The substrate travels through an elongated multi-zone tunnel with independent airflow and temperature loops to flash off volatiles. The dried resin layer is reactivated at a heated chrome lamination cylinder, achieving high bonding cohesion on aluminum barrier foils.
Commercial Converting & Barrier Packaging Segments
Five-Roll Metering Tolerances & Dynamic Tension Matrix
In high-speed solvent-free and dry lamination machine converting lines operating at 500 m/min, roller eccentricity causes adhesive misting, optical orange-peel defects, and web stretch telescoping. OYANG stabilizes fluid shear and film trackability through verified mechanical tolerances turned on Japanese MAZAK CNC and OKUMA machining centers:
| Converting Subsystem | Engineering Tolerance / Control Spec | Production Quality Guarantee |
|---|---|---|
| Five-Roll Metering Assembly | Total Indicated Runout (TIR) ≤ 0.003 mm | Eliminates micro-gap variation across 1,300 mm widths, ensuring ultra-uniform 0.8–2.5 g/m² PU adhesive transfer. |
| Dynamic Web Tension System | Closed-loop servo control (≤ ±0.1 N sensitivity) | Prevents web curling, stretching, and roll telescoping when laminating ultra-thin 12 μm PET or stretch-sensitive PE films. |
| Chrome Lamination Drum | Mirror finish (Ra ≤ 0.05 μm) with rotary oil heating | Provides uniform thermal fusion on dry lamination lines, eliminating optical cloudiness and air micro-entrapment. |
| T-Die Extrusion Melt Control | PID temperature regulation (±1°C across zones) | Guarantees consistent melt-curtain caliper on nonwoven fabrics, avoiding edge-bead buildup and delamination. |
By coordinating independent Yaskawa multi-servo synchronizers with dynamically balanced rollers processed in our 130,000 m² production center, OYANG lamination lines deliver zero-defect optical clarity and bubble-free bonding at continuous line velocities up to 500 m/min.
