LLDPE 9047 (commonly referred to as DFDA-9047) is a butene-based linear low density polyethylene (LLDPE) film-grade resin, produced by copolymerization of ethylene with alpha-olefins.

It is specifically designed for blown film applications, offering an excellent balance of mechanical strength, processability, and optical properties. This resin is widely used in packaging, agricultural, and industrial film applications.

Main Uses of LLDPE 9047

  • Packaging Films. LLDPE 9047 is widely used in various packaging film applications, including heavy-duty bags, shopping bags, industrial packaging films, and frozen food packaging, where strength, flexibility, and durability are essential.
  • Agricultural Films. It is well suited for agricultural uses such as greenhouse films, mulch films, and covering films, providing good toughness and adaptability to different environmental conditions.
  • Industrial Films. The resin can be applied in stretch film, shrink film, and lamination films, offering reliable mechanical performance and consistent processing behavior.
  • Other Applications. In addition, it is commonly used for garbage bags and general-purpose flexible film products, delivering a balanced combination of performance and cost efficiency.

What performance does this resin offer?

  1. Excellent Strength-to-Toughness Balance. The resin combines high tensile strength with exceptional elongation, enabling the production of films that are both strong and flexible, suitable for demanding applications.
  2. Outstanding Impact and Puncture Resistance. This material provides reliable protection against mechanical stress, reducing the risk of film failure during transportation, handling, and storage.
  3. Stable Processing Performance. It ensures smooth extrusion with good melt strength and bubble stability, contributing to consistent film quality and improved production efficiency.
  4. Reliable Sealing Properties. LLDPE 9047 delivers strong and consistent heat seals at relatively low sealing temperatures, supporting high-speed packaging operations and secure product containment.
  5. Flexibility for Blending and Modification. Easily compatible with LDPE and other LLDPE grades, allowing manufacturers to tailor optical properties, stiffness, and processing behavior according to specific requirements.
  6. Wide Application Versatility. Suitable for a broad range of applications, including packaging, agricultural, and industrial films, making it a cost-effective and adaptable material choice.
