Low-density polyethylene (LDPE film-grade resin)

Description

1. Product Overview

This is a high-purity Low-density polyethylene (LDPE) film-grade resin, engineered specifically for blown and cast film extrusion. It is primarily used in flexible packaging, including shrink wrap, stretch film, and industrial liners. The key value proposition is its superior melt strength and optical clarity, which drive higher line speeds and lower rejection rates. Strategically, it fills the gap between commodity LDPE and premium specialty grades, offering reliability for high-volume converters amid tightening virgin resin supplies.

2. Key Specifications & Technical Characteristics

• Chemical composition: Low-density polyethylene (LDPE) homopolymer

• Purity level: ≥99.5% virgin resin, no recycled content

• Physical characteristics: Natural translucent white pellets; melt flow index (MFI) 0.25–0.75 g/10min (190°C/2.16kg); density 0.918–0.924 g/cm³; film haze <10%

• Packaging options: 25 kg sealed PE bags, 625 kg FIBCs, or bulk truck/silo delivery

• Shelf life: 24 months in original unopened packaging, stored below 40°C away from UV

3. Core Industrial Applications

• Primary industries: Flexible packaging, agriculture, construction, and consumer goods

• Specific use cases: Heavy-duty shipping sacks, collation shrink film, silage stretch wrap, and laminated pouch inner layers

• Performance advantage: Higher melt strength reduces edge weave and bubble instability vs. LLDPE, enabling thinner gauges (15–30µm) without tearing

• Efficiency gain: Broader processing window (160–200°C) lowers energy consumption by 8–12% compared to traditional LDPE grades; excellent hot-tack strength minimizes seal failures

4. Competitive Advantages

• Quality consistency: Lot-to-lot MFI variance ≤0.05 g/10min, backed by ISO 9001:2025 certified batch testing

• Supply reliability: Dedicated production line with 99.2% on-time-in-full (OTIF) delivery over 18 months

• Logistics capability: Multi-port warehousing (Rotterdam, Houston, Shanghai) for 72-hour dispatch to major industrial zones

• Cost competitiveness: Fixed quarterly pricing available on annual contracts, removing spot-market volatility

• Sustainability: Mass-balance ISCC PLUS certified; contains 30% certified circular polymer upon request

• Technical support: Full TDS, MSDS, and processing guide included; on-call extrusion engineer support

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT (20 metric tons) per shipment

• Loading capacity: 25–27 MT per 20-foot dry container (FIBC or bagged); 24–26 MT per reefer container (temperature-controlled)
