Cost-Effective 2-Layer Stretch Film Making Machine for Basic Packaging

Cost-Effective AB Dual-Layer Co-Extrusion Engineering

Designed for optimal operational economy and seamless daily production, our 2-layer co-extrusion system delivers reliable film performance while drastically minimizing resin costs. By utilizing a proven AB layer distribution, manufacturers can optimize raw material allocation:

• Cling & Tack Layer (A): Specially formulated for high surface adhesion to ensure secure, slip-free pallet stabilization during transport.
• Core Strength Layer (B): Engineered to handle prime LLDPE, blend resins, or cost-saving recycled material without degrading tensile properties.
• This targeted layer separation reduces overall raw material expenses by 10–15% compared to monolayer extrusion, offering packaging suppliers a rapid return on investment (ROI).

Thermal Stability & Simplified Processing

To ensure consistent melt quality and minimize gauge variation during continuous runs, the 2-layer line features dual independent extrusion units calibrated within a precise 180°C to 230°C thermal range:

• Precision Barrier Screw Design: Optimized screw geometry ensures thorough melt homogenization, effectively eliminating un-melted gels and flow lines.
• High-Efficiency T-Die: Fine-tuned die lip adjustments maintain tight film thickness tolerance within ±3%, ensuring uniform film roll formation.
• Rapid Chill-Roll Cooling: Large-diameter chrome-plated cooling rollers swiftly quench the extrudate, locking in optical transparency, puncture resistance, and elongation.

High-Yield Output & Non-Stop Winding Automation

Engineered for ease of operation and low maintenance, the 2-layer machine integrates robust automation features to maximize daily throughput:

• Dual-Position Winding Unit: Enables smooth, non-stop roll changes without halting the extrusion process, reducing operational downtime and scrap generation.
• Stable Pre-Stretch Capability: Produces film with up to 250–300% elongation, delivering consistent holding force for light-to-medium industrial load wrapping.
• Compact Footprint & Low Energy Consumption: Streamlined machine architecture reduces power usage and factory space requirements, making it the ideal entry-level or expanding solution for packaging converters.

Target Applications & Industry Compliance

The film produced by this system provides a cost-effective wrapping solution across diverse industries:

• Standard palletized logistics and e-commerce warehouse packaging.
• Boxed goods, food & beverage outer wrapping, and paper carton protection.
• Agricultural silage and light-to-medium industrial cargo containment.
