Plastic Laminating Machine

Product Overview

Jiuyi dry laminating systems execute continuous solvent-based or water-based adhesive bonding between multi-layer flexible webs including BOPP, CPP, PET, PE, aluminum foil, and paper. The structural framework utilizes 50 mm thick high-strength alloy cast-iron side wall boards stress-relieved via high-temperature annealing to eliminate residual internal stresses and maintain roller parallelism under continuous high-speed operation.
The web path integrates dual-station unwinding with automatic Edge Position Control (EPC), gravure roll adhesive application via a micro-adjustable doctor blade, a 7.5-meter intelligent drying tunnel containing 24 high-velocity air-knife nozzles, heated hot-drum nip rolling, and torque-motor-controlled rewinding. AC vector frequency drives synchronize each sectional drive to stabilize web tension and prevent substrate elongation.

Machine Types

Substrate combinations and barrier specifications determine the required configuration. Jiuyi manufactures three primary series:

Series / Model	Max. Laminating Width	Max. Speed	Substrate Compatibility	Primary Application
YWGF-800A	800 mm	80 m/min	BOPP, CPP, PET, PE, Paper (18 - 100 um)	Food pouches, paper window bags
YWGF-1100A	1100 mm	80 m/min	Multi-layer films, Aluminum foil, Paper	Industrial barrier packaging, snack bags
Custom High-Speed	1300 mm+	Up to 130 m/min	Co-extruded films, Non-woven fabrics	High-volume conversion facilities

Key Features

Tension Control Architecture

Unwind air shafts utilize magnetic powder brakes (plus-minus 0.1 kg manual adjustment precision), while rewinding uses dedicated torque motors for uniform roll tightness.

Web Guiding Systems

Independent optical EPC units on each unwinder provide plus-minus 60 mm lateral correction travel to eliminate telescoping.

Drying Tunnel Mechanics

Enclosed 7.5-meter drying path featuring 24 air-knife nozzles (1200 cubic meters per hour intake capacity) and 4-zone independent electrical temperature control (plus-minus 2 degrees Celsius accuracy).

Gravure Coating Assembly

Shaftless anilox cylinder installation with precision doctor blades maintaining an adhesive grammage variance within plus-minus 0.5 grams per square meter.

Paper-Plastic Window Bags: Transparent plastic films laminated to kraft or art paper for retail visibility bags.

Aluminum Foil Laminates: Paper or plastic combined with aluminum foil for moisture-sensitive pharmaceutical packaging.

Non-Woven Composites: Bonding non-woven textiles with protective polyethylene layers for industrial applications.

Customization

Web Width Scaling

Custom frame extensions up to 1300 mm or specialized narrow configurations.

Adhesive System Adaptation

Upgraded exhaust blowers and explosion-proof safety integrations for solvent-based versus water-based formulations.

Unwind Configurations

Specialized shafts for heavy aluminum foil rolls or hydraulic floor-pickup lifts.

Drying Zone Extensions

Lengthened tunnel modules for higher speed thresholds or high-solid adhesive formulations.

Company Advantages

01/

Heavy-Duty Structural Rigidity: Cast-iron alloy wall boards (50 mm thickness) prevent frame flex under high-load operations.

02/

Verified Component Selection: Drive systems utilize AC frequency control motors, precision hollow guide rollers (phi 75 mm), and stable torque-transmission assemblies.

03/

In-House Machining Control: Wall panels, guide rollers, and anilox cylinders are finished on internal floor-type boring and turning machinery to maintain concentricity.

04/

Global Deployment Track Record: Machinery operating in over 30 countries across Southeast Asia, the Middle East, and South America, supplied with complete mechanical and electrical schematics.

Manufacturing & Quality Control

Raw Material Integrity: Castings undergo thermal stabilization treatments before precision CNC milling.

Dynamic Roll Balancing: Rotating guide rolls, coating rolls, and heat drums are dynamically balanced to G2.5 grade to minimize vibration.

Pre-Shipment Testing: 72-hour mechanical dry-runs and electrical synchronization checks executed on the factory floor; third-party inspection agencies (SGS, TÜV) welcomed for FAT witness testing.

Surface Protection: Unpainted steel surfaces receive anti-corrosion treatments, paired with industrial-grade enamel exterior coatings.

Installation & After-Sales Support

On-Site Commissioning

Technicians dispatched for machine positioning, leveling, utility connection, and initial material trial runs.

Operator Training

On-site instruction covering parameter programming, tension balancing, and doctor blade maintenance.

Spare Parts Availability

Standard wear components (tension pads, heating elements, air shaft seals) stocked for international courier dispatch within 48 hours.

Remote Technical Guidance

Secure industrial gateways enabled for remote PLC program diagnostics and troubleshooting.

FAQ

Q: What is the standard production lead time?

A: Standard configurations require 60 to 75 days from contract confirmation and deposit receipt.

Q: What is the maximum solvent evaporation rate of the drying tunnel?

A: The 7.5-meter oven features 24 adjustable air-knife nozzles with an intake capacity of 1200 cubic meters per hour, engineered for operations up to 80 m/min.

Q: Can this machine process bare aluminum foil without wrinkling?

A: Yes, via an optional dedicated aluminum foil tension shaft integrated into the second unwinding station for independent tension control.

Q: What utility connections are required on-site?

A: A 3-phase industrial power supply, compressed air at 0.6 to 0.8 MPa, and appropriate exhaust ducting connected to the drying tunnel exhaust port.

Q: How is tension maintained between the coating section and the hot drum?

A: Tension isolation is maintained using synchronized floating dancer rollers and precision AC frequency inverter drives linking gluing roller and hot drum speed ratios.
