Product Overview

Five-layer/Seven-layer Co-extrusion Film Machine (High-Barrier Film) This is cutting-edge equipment specifically designed for producing high-performance, high-barrier nylon (PA) composite films. The device utilizes internationally advanced multi-layer co-extrusion technology, precisely combining materials with distinct properties—such as nylon (PA), polyolefins (PE/PP), and adhesive resins (Tie)—within a single machine. The resulting films exhibit unparalleled oxygen barrier properties, excellent aroma retention, superior mechanical strength, and exceptional puncture resistance.

It integrates advanced extrusion, intelligent control, efficient cooling, and stable winding modules, dedicated to delivering cutting-edge film material solutions for high-end packaging applications in industries such as food, pharmaceuticals, chemicals, and electronics.

Core Features and Technical Advantages

Outstanding multi-layer co-extrusion capability

Precise Layering: Employing advanced spiral die technology, this ensures highly uniform distribution of each material layer, with layer thickness ratios precisely adjustable on-the-fly, enabling optimal material performance and cost control.

Perfect barrier structure: Can be designed and implemented as PP/Tie/PA/Tie/PP, PE/Tie/PA/Tie/PE This classic symmetrical structure effectively leverages nylon's barrier properties while also ensuring the heat-sealing and moisture-proof characteristics of polyolefins.

Specialized Optimization for Nylon Processes

Ultra-Powerful Dehumidification and Drying System: Equipped with a large-capacity, high-efficiency dehumidification and drying system specifically designed for highly moisture-sensitive nylon (PA) materials, this ensures the raw material maintains an extremely low moisture content—typically below 250 PPM—effectively eliminating issues such as bubble formation, pinholes, and strength degradation during processing.
Low-shear-force design: The screw and flow channels are specially designed to minimize shear on nylon molecules while ensuring thorough plasticization, thereby preventing material degradation and preserving the material's outstanding mechanical properties.

Intelligent Control System

Fully Automated Integrated Control: The system features an industrial PC-based PLC control system for seamless human-machine interaction. A touch screen provides centralized control over all process parameters, including temperature, pressure, speed, layer thickness ratio, and more.

Online Thickness Monitoring and Automatic Feedback: Equipped with imported beta-ray or infrared thickness gauges, the system continuously scans the film bubble thickness in real time, while the APC automatic profile control system dynamically adjusts the air ring airflow to ensure that the film thickness tolerance is optimized to an exceptional level—within ±4%.

Outstanding stability and reliability

High-performance core components: Utilizing high-quality alloy steel screw barrels (38CrMoAlA), which undergo nitriding treatment for superior corrosion and wear resistance, this long-life design ensures stable, continuous production.

Independent metered extrusion: Each layer is driven by an independent, precision metering feeding system, ensuring stable and accurate extrusion while eliminating inter-layer interference.

High-efficiency and energy-saving design

IE4/IE5 Energy-Efficient Motors: Choose high-efficiency, energy-saving motors to reduce operating costs.
