Paper Plastic Laminating Machine

The Jiuyi Paper Plastic Laminating Machine integrates unwinding, corona treatment, extrusion/thermal bonding, precision tension control, and surface rewinding into a continuous inline production line. Engineered for packaging converters and paper container manufacturers, it processes raw paper (60 to 450 GSM) and thermoplastic films-including PE, BOPP, PET, and PLA-at stable industrial speeds, ensuring uniform coating thickness and high peel strength in compliance with international food-contact regulations.

Closed-Loop Tension Control: Vector control on unwinding and rewinding stations maintains constant web tension within +/- 1 N, preventing substrate elongation, edge wandering, and telescoping.
High Interfacial Adhesion: Optimized nip roll pressure combined with thermal pre-treatment stations prevents delamination during downstream die-cutting and container forming.
Energy-Efficient Thermal Management: Multi-zone PID temperature controllers paired with insulated heating drums reduce thermal inertia and cut operational power consumption by 15%.
Non-Splicing Turntable Units: Dual-position turret unwinders and rewinders enable flying splice operations up to 150 m/min, minimizing master roll changeover downtime.

Food & Beverage Containers: PE-coated paper stock for disposable paper cups, soup bowls, ice cream containers, and wrapping sheets (FDA and EU 10/2011 compliant).
Medical & Pharmaceutical Packaging: Sterile barrier paper and pouch materials requiring airtight polymer coatings.
Industrial & Consumer Goods: Laminated kraft paper and board for heavy-duty cartons, shopping bag reinforcements, and release paper backings.
Eco-Friendly Packaging: Biopolymer coating processing (PLA, PHA) on paper substrates to meet compostable standards (EN 13432 / ASTM D6400).

Inline Flexographic Printing: Configurable units for pre-lamination or post-lamination branding.
Corona Treatment Upgrades: Dual-side treaters for high-dyne-level surface activation on specialized substrates.
Edge Trim Recycling: Integrated inline trim cutting and pneumatic scrap regranulation systems.
Custom Roll Handling: Unwind and rewind shaft configurations tailored to existing core sizes (3-inch, 6-inch, or shaftless hydraulic chucks).

Produced in a 15,000-m2 facility equipped with heavy-duty CNC boring and milling centers, gantry machining centers, and dynamic balancing rigs.
In-House Machining: Critical components-including extruder screws, barrels, chill rolls, and guiding rollers-are machined internally to maintain strict geometric tolerances.
Dynamic Balancing: Chill rolls and main guide rollers undergo high-precision dynamic balancing at 2,000 RPM to eliminate high-speed web flutter.
Factory Acceptance Testing (FAT): Every machine undergoes a mandatory 72-hour continuous dry-run and load test. Temperature stability, drive synchronization, and vibration data are archived by serial number.
Compliance Standards: Built to CE electrical safety directives and ISO 9001 quality management standards.

Utility Planning: Civil engineering layout drawings, electrical schematics, and pneumatic requirements provided within 2 weeks of order confirmation.
On-Site Supervision: Jiuyi mechanical and electrical engineers handle equipment positioning, leveling, utility hookup, and cold/hot commissioning.
Operator Training: Hands-on training covers startup sequences, tension profile adjustments, HMI recipe storage, and routine preventive maintenance.

Remote Diagnostics: Integrated IoT gateway modules allow secure remote log-in for PLC error log analysis and drive parameter optimization.
Spare Parts Stocking: Critical wear items-including heating bands, thermocouples, pneumatic seals, and drive belts-are maintained in stock for same-day dispatch.
Maintenance Programs: Scheduled service intervals and wear-part replacement guides supplied to maximize operational uptime.
