Overview
White polyethylene net is a versatile plastic mesh made from high-density polyethylene (HDPE) polymers. Its woven or knitted structure provides a balance of strength and flexibility, making it suitable for both industrial and agricultural uses. The material's inherent resistance to moisture, chemicals, and UV degradation ensures long service life even in outdoor environments. Manufacturers often add UV stabilizers to enhance weatherability for extended outdoor applications.
Physical and Chemical Properties
The net exhibits high tensile strength (typically 20–50 kN/m depending on density) with low elongation under load. Its closed-cell structure prevents water absorption, maintaining performance in wet conditions. Chemically inert, it resists acids, alkalis, and most organic solvents. The white coloration provides light reflection benefits in agricultural applications while offering visibility in safety uses. Temperature resistance ranges from -50°C to +80°C for continuous use.
Main Applications
In agriculture, it serves as shade nets for crop protection (30–70% shading rates), windbreaks, and anti-hail covers. The construction industry uses it as debris containment nets and fall prevention systems. Other uses include packaging nets for fragile items, aquaculture containment systems, and temporary fencing. Specialized versions exist for specific applications like greenhouse roofing or sports field protection.
Safety and Storage
While non-toxic, cutting the net may generate plastic particles—ventilation and PPE are recommended during processing. The material is not biodegradable but is recyclable under PE-LD/HD waste streams. For storage, keep rolls on pallets in covered areas to prevent deformation. Avoid prolonged exposure to temperatures above 60°C which may cause sagging. Shelf life typically exceeds 5 years when stored properly.
B2B Procurement Guide
Key specifications to verify include mesh size (commonly 2–20mm), weight (80–300 gsm), and UV stabilization level (minimum 5% for outdoor use). Request material certificates for food-grade or heavy-duty applications. Bulk buyers should compare knot types (raschel-knitted vs. extruded) for their specific needs. Lead times for custom sizes/colors typically range 2–4 weeks. Consider MOQ requirements (often 500–1000m²) when sourcing directly from manufacturers.
