Linear low-density polyethylene (LLDPE stretch-film resin)

Description

1. Product Overview
This product is a high-performance Linear Low-Density Polyethylene (LLDPE) stretch-film resin, engineered specifically for the production of cast and blown stretch films used in high-speed pallet wrapping. Its primary industrial application is securing and unitizing heavy or irregularly shaped loads for logistics and warehousing. The key value proposition is an exceptional elongation-at-break and superior puncture resistance, which enables down-gauging—reducing material usage by up to 20% without compromising load stability. In a market driven by e-commerce growth and supply chain efficiency, this resin is strategically critical for reducing total cost of ownership and plastic waste in secondary packaging.

2. Key Specifications & Technical Characteristics

• Chemical composition: LLDPE (C4–C8 copolymer), butene-based or hexene-based options available

• Purity / Grade: Virgin, industrial grade; no regrind, no contaminants

• Physical characteristics:

  • Form: Spherical pellets (extrusion grade)

  • Color: Natural translucent white

  • Melt Flow Index (MFI): 1.0–3.5 g/10 min (2.16 kg @ 190°C) – grade dependent

  • Density: 0.918 – 0.925 g/cm³

  • Bulk density: 500–550 kg/m³

• Packaging options: 25 kg heat-sealed PE bags, 550–650 kg FIBC jumbo bags, or silo truck delivery

• Shelf life: 24 months when stored below 50°C, away from UV light and moisture

3. Core Industrial Applications

• Primary industries: Logistics & warehousing, food & beverage, pharmaceuticals, building materials, e-commerce fulfillment, and paper/ pulp.

• Operational use cases:

  • High-speed cast stretch film for automated pallet wrappers

  • Blown stretch film for hand wrap or irregular loads with sharp edges (e.g., lumber, metal coils)

  • Pre-stretch film applications requiring 200–300% pre-stretch ratios

• Performance advantage: Compared to conventional LLDPE grades or LDPE blends, this resin delivers 40% higher puncture resistance and 60% higher ultimate elongation (up to 600%), reducing film breaks during wrapping and transit. The consistent rheology ensures lower extruder torque and energy consumption (up to 12% savings) for converters.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production with real-time SPC monitoring; lot-to-lot MFI variance ≤ ±0.2 g/10 min.

• Supply reliability: Dual-sourced feedstock from Saudi Arabia and North America; 24/7 operation with 15,000 MT monthly production capacity.

• Logistics capability: Bagged, jumbo, or bulk pneumatic delivery via owned truck fleet and rail-served warehouses in three continents.

• Price competitiveness: Formula-based quarterly pricing + long-term contracts with price collar options.

• Sustainability: Contains no PFAS; compatible with 30% post-consumer recycled (PCR) content blending. Available with ISCC PLUS mass-balance circular certification.

• Technical support: Free roll-to-roll field trials; process optimization manual; CAE simulation data for die gap and winding tension.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (one full truckload) for bagged or jumbo bags; 45 MT for bulk pneumatic delivery.

• BULK 20MT loading capacity: 20 MT ± 5% per standard 20-ft dry container (20 pallets stacked, 1,000 kg each, stretch-wrapped and load-secured).
