LLDPE Stretch Film with 1inch or 3inch Paper Core 85% Material Recovery Rate and Linear Low-Density Polyethylene for Industrial Packaging

As a foundational solution for logistics and packaging, our PE (Polyethylene) Stretching Film is engineered with advanced polymer blending and extrusion technology, delivering exceptional mechanical stability, application versatility, and cost efficiency. Below is a detailed technical breakdown to support procurement decisions and scenario-specific deployments.

• Resin Grade: Food-safe Linear Low-Density Polyethylene (LLDPE) blend, with a melt flow rate (MFR) of 2.3g/10min (tested at 190℃ under 2.16kg load). This ensures low-temperature toughness (no brittle fracture at -40℃) and thermal stability for continuous use up to 60℃.
• Functional Additives:
  • 0.3% silica-based anti-blocking agent: Prevents film adhesion during unwinding, ensuring smooth operation with automated equipment.
  • 0.2% erucamide slip agent: Reduces coefficient of static friction to ≤0.3, minimizing wear on wrapping machine components.
• Thickness Control: 15μm–50μm (tolerance ±5%), achieved via 3-layer co-extrusion. Thickness uniformity (CV value ≤3%) eliminates weak points that cause tearing.

• Automated Pallet Wrappers: Compatible with 95% of industrial-grade machines (e.g., Lantech, Orion), supporting wrapping speeds up to 15 pallets per hour (for pallets of Φ1.2m * H2.0m). Adjustable unwinding tension (5–15N) prevents equipment jamming.
• Manual Dispensers: Lightweight roll design (core diameter 76mm, roll weight 5kg–20kg) reduces operator fatigue. Tear propagation resistance (≥50N, ISO 6603-2) allows manual cutting without auxiliary tools.

• Food & Beverage Sector: Complies with FDA 21 CFR 177.1520 and EU Regulation (EC) No. 10/2011, free of phthalates and heavy metals. Moisture barrier properties extend the freshness of bulk produce, baked goods, and dairy products by 3–5 days.
• Heavy-Duty Industrial Use: The 50μm thick variant offers puncture resistance ≥80N (ISO 6603-2), ideal for wrapping machinery parts, steel bars, and construction materials—preventing film breakage during forklift operations.
• E-Commerce & Retail: The 15–25μm light-duty variants balance flexibility and cost, perfect for securing multi-box orders and fragile items (e.g., electronics, ceramics) without adding excess weight.

• Real-Time Monitoring: In-line laser thickness gauges (accuracy ±1μm) and hourly tensile testing ensure batch-to-batch consistency.
• Environmental Durability: Passes 100-cycle temperature shock tests (-40℃ to 60℃) and 500-hour humidity tests (90% RH at 40℃) with no delamination, discoloration, or performance loss.

• Recyclability: Classified as recycling code 4 (LDPE/LLDPE), with 85% material recovery rate via standard PE recycling processes.
• Biodegradable Variant: Available with PBAT (Polybutylene Adipate Terephthalate) blending, achieving ≥90% biodegradation in 180 days (per ASTM D6340)—aligned with carbon-neutrality goals.

We offer tailored solutions to meet specific user needs:

• Thickness & Size: Customizable from 15μm (light-duty) to 50μm (heavy-duty), with roll lengths of 200m–1000m.
• Surface Treatment: Glossy finish (enhanced moisture barrier) or matte finish (anti-glare for printed packaging).
• Documentation: Full technical package provided, including Material Safety Data Sheets (MSDS), performance test reports, and equipment compatibility guides—supporting customer quality audits.
