Roll-to-roll laminating machine

automatedhigh-speeddry

Product Overview
Dry lamination machine designed to bond multiple layers of film, aluminum foil and paper using water-based adhesives and high-solid solvent-reduced systems. Intended for sustainable packaging applications in food, pharmaceutical and daily-chemical sectors. Features reduced VOC emissions, compatibility with biodegradable films and industrial mechanical speeds (typical 350–450 m/min depending on adhesive).

Short technical summary

• Maximum film width: 1050 mm or 1250 mm
• Unwinding diameter: Φ 800 mm
• Rewinding roll diameter: Φ 800 mm
• Drying tunnel length (material inside oven): 9 m with multiple heating zones
• Compatible printing materials: film, aluminum foil, paper; supports biodegradable films (PLA, BOPE, cellophane)

Key Technical Advantages

• Smart Energy Management — drying systems recover a large portion of process heat and use heat exchangers to preheat intake air, reducing energy consumption by 30–40% versus standard models.
• Superior Material Handling — engineered for sensitive eco-materials; heavy-duty servo drives and low-friction idler rollers maintain tension accuracy (±0.1 kg) to prevent stretching or tearing of biodegradable films.
• Exceptional Coating Precision — direct-drive coating units provide precise coat-weight control typically between 1.5–4.0 gsm (dry) for uniform adhesion across the web.
• Built-in Safety & Compliance — integrated LEL monitoring and interface ports for RTO systems enable compliance with emission control requirements.

Quality and Performance Highlights

• VOC / Residual control — system design minimizes VOC emissions (field reports indicate up to ~40% reduction) to meet environmental benchmarks.
• Residual solvent & moisture — gas chromatography analysis reported residual solvent and moisture below 2 mg/m² in finished laminates.
• Coating uniformity — cross-web variation typically within ±0.1 g/m², ensuring consistent optical clarity and bond strength.
• Bond strength — peel testing per ASTM F904 and ISO 11339; adhesion commonly > 2 N/15 mm for standard films; metallized structures show higher values.
• Drying performance — extended tunnel with high-velocity impinging air nozzles and zoned temperature control (up to 120°C) to enable water-based adhesive drying at industrial speeds.
• Roll quality — automatic edge position control (EPC) with ±1 mm accuracy for flat, telescope-free rolls suitable for downstream slitting.

Application Industries / Uses

• Sustainable food packaging — mono-material structures for snacks, confectionery and pastry products.
• Pharmaceutical and medical packaging — lidding and high-barrier pouches where low residual solvents are critical.
• Heavy-duty retort packaging — bonding structures that withstand retort sterilization (121°C) for pet food and ready-to-eat meals.
• Daily chemical products — laminates for detergent sachets, personal care pouches and other consumer goods.

Materials & Adhesive Compatibility

• Compatible substrates: BOPP, PET, Nylon, Aluminum foil, Paper, PE, biodegradable films (PLA, BOPE, cellophane).
• Adhesive systems supported: water-based adhesives, high-solid solvent-reduced systems, and traditional solvent-based adhesives (hybrid capability with corrosion-resistant components).
