Flexible Packaging Laminating Machine
Jiuyi industrial laminating lines bond dissimilar webs—such as BOPP, PET, CPP, PE, and aluminum foil—via solvent-less, solvent-based, or thermal extrusion processes. Built for continuous 24/7 manufacturing under CE and ISO9001 frameworks, these systems govern web tension and adhesive coat weight to prevent tunneling, curling, and delamination across high-barrier substrates.
Description
Jiuyi industrial laminating lines bond dissimilar webs-such as BOPP, PET, CPP, PE, and aluminum foil-via solvent-less, solvent-based, or thermal extrusion processes. Built for continuous 24/7 manufacturing under CE and ISO9001 frameworks, these systems govern web tension and adhesive coat weight to prevent tunneling, curling, and delamination across high-barrier substrates.
Product Advantages
Closed-Loop Tension Regulation: Servo-driven unwinds and rewinds utilize dancer rollers and load cells to maintain web tension within +/- 1 percent across fluctuating roll diameters, eliminating material elongation and side-register drift.
Precision Metering Systems: Five-roller differential coating assemblies deposit solvent-less adhesives down to 0.8 g/m2 dry weight, cutting chemical usage while preserving bond strength.
Thermal Nip Roll Control: Liquid-heated or oil-circulated steel nip rollers maintain uniform surface temperature distribution across the web width, removing bubbles during high-speed solvent-less bonding.
Quick-Change Sleeve Mechanics: Trolley-mounted coating units and quick-release gravure sleeves limit job changeover downtime to under 30 minutes.

Edge Guidance: Ultrasonic web sensors with +/- 0.1 mm correction precision.
Drive Architecture: Multi-axis independent AC vector servo motors.
Control Terminal: Industrial PLC paired with a 15-inch multi-touch HMI and remote diagnostics module.
Applications
Food & Beverage: Retort pouches, vacuum barrier coffee bags, snack metallized films, and liquid spout pouches requiring puncture and seal strength.
Pharmaceuticals: Cold-form blister foils, child-resistant strip packs, and moisture-barrier desiccant sachet laminates.
Industrial & Household: Refill detergent pouches, heavy-duty fertilizer bags, and chemical-resistant barrier webs.
Customization
Drying Tunnels: 3-to-5 zone independent heating configurations (electric, thermal oil, steam, or natural gas) for solvent evaporation.
Corona Treatment: Inline treaters mounted at unwind stands to increase surface dyne levels on raw polymer films.
Defect Detection: Provisions for 100% camera-based print and lamination inspection integration.
Inline Slitting: Circular shear or razor slitters added at the rewind station for simultaneous edge-trimming and multi-reel separation.
Manufacturing & Quality Control
Structural Machining: Machine frames utilize Q345B heavy-gauge structural steel, annealed at 600 degrees C to eliminate internal stress, then finished on CNC floor boring mills in a single setup to maintain roll parallelism within 0.01 mm.
Dynamic Balancing: All guide rolls, coating cylinders, and chill drums undergo dynamic balancing to G2.5 grade to suppress vibration at speeds up to 500 m/min.
Component Sourcing: Drive components, pneumatic actuators, and bearings utilize tier-one international hardware (NSK, SKF, Festo, SMC).
Factory Testing: 72-hour continuous dry-run trials paired with live test runs using customer-supplied substrates prior to crating, verified under ISO9001 and CE protocols.

Spare Parts Stock: High-wear items-including drive belts, pneumatic seals, and electronic cards-maintained in regional inventories for immediate air dispatch.
Service Plans: Annual inspection contracts providing mechanical wear evaluations and precision calibration checks.
FAQ
Q: What curing time is required for solvent-less laminates?
A: Solvent-less laminates require a chemical curing period of 24 to 48 hours in a controlled environment (40 degrees C to 50 degrees C), governed by the specific 2-component polyurethane adhesive used.
Q: Can this line process biodegradable substrates like PLA and PBAT?
A: Yes. Bio-based films feature lower tensile thresholds and higher thermal sensitivity. The machine processes PLA/PBAT via low-tension profiles and chilled nip rollers to avoid web elongation.
Q: What utilities are required for installation?
A: Standard utility inputs require a 3-phase 380V/480V (50Hz/60Hz) power supply scaled to model kilowatt ratings, compressed air at 0.6 MPa (300 L/min), and chilled water circulation at 15 degrees C to 18 degrees C.
Q: How are urgent component replacements handled?
A: Standard wear parts ship from stock within 24 hours via air freight. Proprietary structural components include full engineering drawings to allow immediate local machining if necessary.
