Applications
Dow, a global leader in materials science and innovation, has been at the forefront of developing high-performance polymers that redefine industry standards. With a commitment to sustainability and cutting-edge technology, Dow’s experimental Linear Low-Density Polyethylene (LLDPE) grades—XUS 89770.03 and XUS 89770.05—offer tailored solutions for blown film applications demanding exceptional durability, clarity, and versatility.
XUS 89770.05: Strength and Performance with Enhanced Processing:
The XUS 89770.05 grade is a hexene-based metallocene LLDPE (C-6) designed for applications requiring robust strength and reliable sealing performance. With a 1.0 Melt Flow Index (1MFI), this grade delivers excellent dart impact resistance (ideal for heavy-duty packaging like shipping sacks) and maintains good optical properties, including a balanced haze level for clarity in food and industrial films. Its formulation includes slip additives (990 ppm) to enhance processing efficiency, making it easier to handle during production. The material’s superior tensile strength and puncture resistance ensure durability in demanding environments, such as frozen food packaging or agricultural films. This grade is particularly suited for applications like pet food bags, shrink films for pallet wrapping, and construction sheeting, where high-speed processing and resistance to tearing under stress are essential. Its versatility extends to fresh produce packaging, combining puncture protection with the clarity needed to showcase product quality.
XUS 89770.03: Premium Clarity and Puncture Resistance:
The XUS 89770.03 grade, also a hexene-based metallocene LLDPE (C-6), prioritizes optical excellence and puncture resistance. With the same 1.0 Melt Flow Index (1MFI) but no added slip agents, this grade excels in applications where clarity is critical, such as fresh produce or cheese packaging, thanks to its low haze (11%) and high gloss. Its non-slip formulation ensures stable film layers, while outstanding puncture force and toughness make it ideal for protective films in construction or industrial uses. This grade strikes a perfect balance between transparency and mechanical performance, catering to markets that prioritize both aesthetics and durability. It is particularly well-suited for high-clarity frozen food pouches, retail-ready packaging for deli meats, and agricultural films requiring visibility of crops, as well as industrial liners where puncture resistance and optical quality must coexist. Its ability to maintain structural integrity under stress makes it a top choice for shrink films and protective covers in harsh environments.

Designed for blown film applications, these grades leverage gas-based metallocene catalysts and non-fluoro-based processing aids—a critical advantage over traditional fluorinated alternatives, reducing environmental concerns while maintaining efficiency. The XUS 89770.03 demonstrates superior CD tear resistance (125% vs. a competitor’s 50% for similar mILD grades*), ensuring durability in applications like industrial films or agricultural sacks. Meanwhile, the XUS 89770.05 balances high puncture resistance with optimized slip additives (990 ppm) for smoother processing, ideal for heavy-duty packaging and multi-layer films where enhanced processability ensures consistent layer adhesion. Both resins maintain excellent optics (low haze) and mechanical strength, even at a density of ~0.917-0.9205 g/cm³, outperforming rival grades in tear, dart impact, and modulus properties. Additionally, Dow’s formulations feature a broader sealing range, critical for oil and liquid packaging applications where leak-proof integrity is paramount. By eliminating trade-offs between clarity, toughness, and processability, Dow sets a new benchmark for high-performance, eco-conscious polyethylene solutions that excel in demanding environments.
Regulatory Compliance:
Both XUS grades adhere to rigorous global safety standards, ensuring reliability in sensitive applications. The XUS 89770.05 is certified under U.S. FDA FCN 1539 and *EU Regulation 10/2011*, meeting strict requirements for food-contact materials, including migration limits and chemical safety. The XUS 89770.03 complies with U.S. FDA FCN 1539, guaranteeing suitability for food packaging like fresh produce or frozen goods. Dow’s formulations exclude harmful additives, aligning with global product stewardship principles. These certifications underscore Dow’s commitment to delivering materials that prioritize human health, environmental responsibility, and compliance with regional regulatory frameworks.
