Roll-to-roll laminating machine

automatedhigh-speeddry

Overview
Our dry multi-function laminator is engineered for modern flexible-packaging production. It bonds multiple flexible substrates — including BOPP, PET, PE, CPP, aluminium foil and paper — using precision adhesive application and multi-zone drying control. The machine is suitable for food, pharmaceutical, daily-chemical packaging and industrial laminate applications.

Key Features

• Substrate compatibility: BOPP, PET, PE, CPP, aluminium foil, paper.
• Precision tension control for delicate films (tension accuracy ±0.3 kg).
• Multi-zone drying tunnel with intelligent temperature control to minimise solvent residue (target <5 mg/m² per ASTM F1884).
• Cassette-type coating trolley for rapid changeover between solvent-based and water-based adhesives (15–30 minutes).
• Energy-efficient design with exhaust air recirculation and adjustable fresh-air ratio.
• Automatic splicing at unwind and rewind stations to reduce waste and maintain continuous production.
• Synchronized multi-motor AC vector drive for smooth handling of sensitive substrates.

Applications
Designed for flexible packaging production including food packaging (retort pouches, coffee bags), pharmaceutical packaging (cold-form foil, blister materials), daily-chemical packaging and industrial laminates for insulation or electronic shielding.

Quality Verification Methods

• Solvent retention measurement by gas chromatography.
• Bond strength testing with tensiometer following ASTM methods.
• Coating uniformity inspection via optical detection systems.
• Web alignment verification within ±1 mm tolerance.
• Temperature distribution checks using thermal imaging.

Core Advantages

• Fast changeover via cassette-type coating trolley for flexible production runs.
• Energy saving through exhaust air recirculation and automatic fresh-air ratio adjustment.
• Minimal waste using automatic splicing at unwind and rewind stations.
• Consistent bond quality with precision-controlled laminating nip and gravure coating cylinders maintaining adhesive application accuracy within ±0.1 g/m².

How It Solves Common Production Challenges

• Prevents curl in mixed-thickness laminates using independent tension control for each web and a temperature-controlled cooling nip to stabilise the laminate immediately after bonding.
• Handles delicate substrates without breaks using synchronized vector motor drives and low-friction guide rollers to minimise contact stress.
• Maintains high speed without compromising drying quality using high-velocity air knife technology in the drying tunnel.
