PE Stretching Film with Food-Grade Compliance High Tensile Strength and UV Resistance for Industrial Packaging

As a critical auxiliary material in logistics packaging, our PE Stretching Film is engineered with high-density polyethylene (HDPE) and modified processing technology, delivering stable mechanical properties, excellent adaptability, and cost-efficiency. Below is a detailed technical breakdown to support procurement decision-making and scenario-specific application.

• Resin Grade: Food-grade HDPE (LLDPE blend, melt flow rate 2.3g/10min @190℃/2.16kg), ensuring low-temperature toughness (-40℃ no brittle fracture) and high-temperature stability (continuous use ≤60℃).
• Additive System: Contains 0.3% anti-blocking agent (silica-based) to prevent roll sticking during unwinding, and 0.2% slip agent (erucamide) to reduce friction coefficient (static friction coefficient ≤0.3) for smooth automated wrapping.
• Thickness Control: 15μm–50μm (tolerance ±5%), with uniform thickness distribution (CV value ≤3%) via 3-layer co-extrusion technology, avoiding local thin spots that cause tearing.

• Automated Wrapping Machines: Matches 95% of industrial-grade pallet wrappers (e.g., Lantech, Orion), supporting wrapping speed up to 15 pallets/hour (diameter 1.2m, height 2.0m). The film’s consistent unwinding tension (5–15N adjustable) avoids equipment jamming.
• Manual Dispensers: Lightweight roll design (core diameter 76mm, roll weight 5kg–20kg) reduces operator fatigue; the film’s tear resistance (tear propagation resistance ≥50N) allows manual cutting without auxiliary tools.

• Food-Grade Application: Complies with FDA 21 CFR 177.1520 and EU Regulation (EC) No. 10/2011, free of plasticizers (phthalates) and heavy metals, suitable for wrapping fresh produce, baked goods, and bulk food (extending freshness by 3–5 days via moisture barrier).
• Heavy-Duty Industrial Use: For machinery parts, building materials (e.g., steel bars), the 50μm thick variant offers puncture resistance ≥80N (ISO 6603-2), preventing film breakage from sharp metal edges during forklift handling.

• Online Monitoring: Uses laser thickness gauges (accuracy ±1μm) and tensile testing machines (real-time sampling every 2 hours) to ensure batch consistency.
• Environmental Adaptability Test: Passes 100-cycle temperature shock test (-40℃ to 60℃) and 500-hour humidity test (90% RH, 40℃) with no delamination, discoloration, or performance degradation.

• Recyclability: Recyclable via PE-specific recycling processes (recycling code 4), with 85% material recovery rate.
• Biodegradable Variant: Offers PBAT-blended PE film (biodegradation rate ≥90% in 180 days per ASTM D6340), suitable for brands with carbon neutrality goals.

We provide tailored solutions based on customer needs:

• Thickness Customization: 15μm (light-duty, e-commerce) to 50μm (heavy-duty, industrial).
• Surface Treatment: Matte finish (anti-glare, for printed packaging) or glossy finish (enhanced moisture barrier).
• Technical Documentation: Offers material safety data sheets (MSDS), performance test reports, and equipment matching guidelines to support customer quality audits.
