The high-performance co-extrusion line is engineered to manufacture advanced volatile corrosion inhibitor (VCI) stretch film. It provides automated, single-step packaging solutions that combine heavy-duty pallet stabilization with continuous molecular rust prevention for global maritime export.
Target Applications and Industrial Use Cases
The anti-rust stretch film manufacturing machine for metal pallets is specifically designed to produce protective packaging for high-value, corrosion-sensitive goods.
- Metallurgical Products: Heavy-duty wrapping for bulk steel coils, wire rods, and sheet metal pallets.
- Automotive Industry: Secure protection for stamped auto parts, engines, and body-in-white components.
- Precision Engineering: Preservation of machined tooling, CNC components, and industrial bearings.
- Maritime Export: Heavy palletized cargo transported via ocean freight, transit holds, and international containers.
Anti-Corrosion Protection in Extreme Environments
The line integrates chemical engineering with extrusion technology to safeguard metal assets against severe transit and storage hazards.
- VCI Molecular Shielding: Injects up to 5,000 ppm of premium amine-based volatile corrosion inhibitors into the LLDPE matrix.
- High-Humidity Resilience: Maintains a continuous, active release of 10-12g/m² of inhibitors even in 95% relative humidity (RH) at 40°C.
- Micro-Climate Neutralization: The film continually emits VCI molecules that saturate the enclosed air, neutralizing moisture, salt air, and condensed water inside the pallet.
- Long-Term Storage: Provides up to 24 months of continuous rust protection, eliminating the need for greasy oil coatings, rust-proofing sprays, or temporary desiccant packs.
Heavy-Duty Pallet Packaging and Mechanical Strength
To withstand the physical abuse of industrial shipping, the manufactured film delivers exceptional mechanical and structural integrity.
- Puncture and Tear Resistance: Configurable for 3-layer or 5-layer co-extrusion, sandwiching a functional VCI core between two high-strength skins to resist sharp strapping edges and metal burrs.
- High-Stretch Load Containment: Achieves up to 300% stretch capacity, replacing heavy 90-micron traditional film with high-efficiency 50-micron co-extruded film without losing hold force.
- Forklift & Transit Buffering: Prevents film puncture and abrasion caused by forklift tines, conveyor friction, and container shifting during cross-Pacific transit.
- Corner Protection: Closed-loop AC servo drives maintain strict tension within ±1.5 grams, preventing film neck-down and thinning at vulnerable sharp pallet corners where moisture typically pools.
High-Throughput Industrial Production Features
Engineered for continuous operation, the system optimizes manufacturing workflows for rapid industrial packaging roll deployment.
- 350 kg/hour Extrusion Output: Delivers high-volume manufacturing for 600 mm wide commercial-grade film rolls.
- ASTM D1749 Salt Spray Compliance: Film produced passes over 500+ hours of rigorous salt spray testing, certifying it for harsh maritime corridors .
- Inline Slitting and Continuous Rewinding: Features a dual-winder turret for zero-stop roll changes and inline slitting, supplying pallet-ready film rolls directly to the shipping dock.
- Streamlined Single-Step Logistics: Enables facilities to wrap, secure, and rust-proof metal cargo simultaneously, ensuring fumigation-free, clean-surface delivery straight to the end destination.
