Overview
In modern flexible packaging, achieving a reliable balance between durability, processing stability, and puncture performance is essential for protecting goods across supply chains. DOWLEX™ 2645.11G Polyethylene Resin, developed by Dow, is a high-performance hexene-based linear low-density polyethylene resin engineered specifically to meet these demands in blown film applications. Formulated with an optimal additive package—including 3,000 ppm antiblock and 1,200 ppm slip—it delivers smooth extrudability and ease of handling during downstream converting.
Mechanical Strength and Balanced Toughness
DOWLEX™ 2645.11G offers robust mechanical integrity designed to withstand external stress and rough handling. With a density of 0.921 g/cm³ and a melt index of 0.90 g/10 min (190°C/2.16 kg), the resin provides consistent structural strength.
Key performance characteristics tested at a 51 µm (2.0 mil) thickness include:
- Tear Resistance: Exceptional Elmendorf tear strength—720 g in the machine direction (MD) and 1,000 g in the transverse direction (TD)—prevents propagation of accidental cuts or tears during transit.
- Tensile & Elongation Capability: Ultimate tensile strength reaches 48.8 MPa (MD) and 39.2 MPa (TD), backed by high elongation at break (660% MD / 740% TD), allowing films to absorb impact without structural failure.
- Puncture & Impact Resistance: Features a dart drop impact value of 300 g and a puncture resistance of 6.62 J/cm³, ensuring reliable protection against sharp edges and localized pressure.
Expanded Application Spectrum
Thanks to its blend of high mechanical toughness and melt stability, DOWLEX™ 2645.11G serves
diverse packaging and industrial needs:
- Heavy-Duty Shipping & Industrial Bags: The combination of high tear and dart drop impact strength makes it suited for multi-wall sack liners, agricultural film wraps, and bulk chemical or fertilizer bags that demand high load containment.
- Food & Consumer Flexible Packaging: Used in coextruded film structures for frozen food, dry goods, and secondary collation wrap. Its tear resistance prevents punctures from rigid product corners, ensuring package integrity from manufacturing to retail shelves.
- Lamination & Protective Overwrap: Acts as a tough functional layer in multi-layer substrate laminates where puncture protection and seal stability are critical to preserving product freshness and security.
- Value Proposition Positioned strategically within the polymer market, DOWLEX™ 2645.11G is priced slightly above standard butene LLDPE, yet remains comfortably below premium Metallocene levels. Because of its robust hexene copolymer structure, incorporating even a slight dosage of this grade into film formulations enhances overall performance while reducing the total amount of expensive metallocene required. This smart blending approach successfully drives down production costs across the final product line without compromising mechanical integrity or toughness.
Regulatory Compliance and Material Safety - DOWLEX™ 2645.11G is formulated to meet stringent international food-contact guidelines, ensuring compliance and peace of mind across regulated global markets:
- U.S. FDA: Complies with FCN 1539 regulations for direct food-contact packaging applications.
- European Union: Adheres to EU Regulation No 10/2011 on plastic materials intended to come into contact with food.
