High-Precision Film Automatic Laminating Line | Jiangsu Laiyi

In modern flexible packaging and high-barrier industrial material manufacturing, automation and continuous precision are essential for profitability. Converting operations require equipment that minimizes manual intervention, reduces material waste, and maintains consistent roll quality across high production speeds.

The Film Automatic Laminating Line manufactured by Jiangsu Laiyi Packing Machinery Co., Ltd. delivers fully automated operation, superior web-tension control, and reliable layer adhesion for global B2B converters.

A Film Automatic Laminating Line is a continuous, high-speed production system designed to coat and bond plastic films (such as BOPP, PET, BOPA, or PE) with other flexible substrates (like paper, aluminum foil, or woven fabric) using molten polymer resin (LDPE, PP, EVA, PLA) as the extruding bonding layer.

Key automation features include:

• Auto Unwind & Rewind Turrets: Non-stop, high-speed material roll changes without slowing or stopping the machine.
• Automatic T-Die & Online Thickness Gauging: Closed-loop monitoring for precise coat weight control across the web width.
• PLC Centralized Automation: Touchscreen parameter adjustments for temperature, speed, tension, and splicing.

At Jiangsu Laiyi Packing Machinery Co., Ltd., we design fully integrated automated lines engineered to handle delicate, heat-sensitive, and high-tension film substrates without deformation.

Flying Splice Automation: Dual-position turret unwinders and rewinders execute automatic roll splicing at full production speeds (up to 300 m/min).

Scrap Reduction: Eliminates web waste generated by stopping and restarting the extrusion system, saving tons of resin and substrate material annually.

Closed-Loop Thickness Control: High-precision online thickness sensors scan the coating film in real time, automatically feeding back adjustments to the motor-driven T-Die bolts.

Resin Savings: Maintains coat weight accuracy within tight tolerances (± 1/㎡), preventing over-coating and saving raw material costs.

Multi-Stage Tension Control: Features Siemens servo drives and tension sensors throughout the unwind, extrusion nip, and rewind zones to prevent film stretching, wrinkling, or thermal shrinkage.

Integrated Corona & Pre-Treatment Units: Equipped with high-output Corona Treaters (e.g., Sherman Corona) and optional Anchor Coating (AC) / Primer units to guarantee maximum bonding strength on non-porous film surfaces.

A Jiangsu Laiyi Film Automatic Laminating Line equips your plant to process materials for high-value global markets:
