    Performance and Features Summary

    Innovative Process: No Pre-Drying, High Efficiency & Energy Saving

    The core advantage of this line is its integrated high-efficiency venting system, which completely eliminates the traditional pre-drying and crystallization steps for PET materials. This not only dramatically simplifies the production workflow but also significantly reduces both capital investment and energy consumption, offering a more streamlined and efficient startup solution.

    ⚙️ Core Design: Ensuring Material Performance & Output Quality

    Segmented Co-rotating Twin Screws: The precise screw configuration enables gentle yet efficient plastication and mixing, minimizing the viscosity loss of PET resin during processing to preserve its inherent superior properties.
    Symmetrical Thin-Wall Calender Rolls: The reinforced cooling structure ensures rapid and uniform sheet cooling, which is critical for increasing line speed and improving sheet flatness and crystallization consistency.

    🎛️ Intelligent Control: Precise Formulation & Stable Production

    Equipped with a multi-component gravimetric dosing system, it allows for precise control over the ratio of virgin material, recyclate, and functional masterbatch. This provides great flexibility for cost optimization and custom material formulations. The advanced automation control system guarantees consistent thickness and production stability throughout the entire process from extrusion to forming.

    Frequently Asked Questions

    Q Does the PET/PLA co-rotating twin-screw extrusion line require pre-drying of PET material before processing?
    No. The line features an integrated high-efficiency venting system that completely eliminates the need for traditional pre-drying and crystallization steps. This significantly simplifies the production workflow, reduces energy consumption, and lowers capital investment compared to conventional extrusion setups.
    Q What sheet thickness range can this extrusion line produce?
    All available models — including Multi Layer, Single Layer, and Highly-efficient configurations — are capable of producing sheets with a thickness range of 0.15 mm to 1.5 mm, making them suitable for a wide variety of packaging and industrial applications.
    Q What is the maximum production capacity of the highly-efficient model?
    The highest-capacity configuration (JWE110+JWE65-1500) can achieve a maximum output of 1,000–1,500 kg/h, driven by a 355/75 kW main motor combination. This makes it ideal for large-scale industrial sheet production operations.
    Q Can the line process both virgin PET/PLA material and recycled content?
    Yes. The line is equipped with a multi-component gravimetric dosing system that allows precise control over the ratio of virgin material, recycled content, and functional masterbatch. This flexibility supports cost optimization strategies and enables customized material formulations to meet specific product requirements.
    Q What industries and applications are the produced sheets suitable for?
    The sheets produced are suitable for a broad range of applications, including premium food and pharmaceutical packaging (thermoformed containers, blisters, lidding films), biodegradable foodservice items (cups, cutlery, trays), medical packaging, automotive interior components, electronic insulation parts, and sustainable disposable or reusable consumer products.
    Q How does the calender roll design contribute to sheet quality?
    The symmetrical thin-wall calender rolls feature a reinforced cooling structure that ensures rapid and uniform cooling of the extruded sheet. This design is critical for achieving higher line speeds while maintaining excellent sheet flatness and consistent crystallization — both of which are essential for downstream thermoforming performance and end-product quality.
