LLDPE 7042N is a versatile film-grade resin that offers a balanced combination of mechanical strength and processing performance for blown film applications. It is derived from the 7042 resin grade and modified through a tailored additive system to enhance processability, anti-blocking performance, and antistatic properties.

With stable extrusion behavior and a wide processing window, 7042N is well suited for packaging, agricultural, and industrial film applications that require consistent quality, reliable production efficiency, and excellent end-use performance.

Recommended Uses of LLDPE 7042N

  • Packaging Films. LLDPE 7042N is widely used in general-purpose packaging films, food packaging bags, shopping bags and carrier bags, as well as trash and liner bags, offering a good balance of strength, flexibility, and processability for everyday packaging needs.
  • Industrial Films. The resin is suitable for industrial film applications such as lamination film substrates, heavy-duty packaging films, and protective films, where consistent performance and durability are required.
  • Agricultural Films. It is commonly used in agricultural mulch films, greenhouse films, and general covering films, providing reliable mechanical strength and environmental resistance in outdoor conditions.
  • Other Applications. LLDPE 7042N is also applied in roll bags, liner films, and light-duty industrial films, supporting a wide range of flexible packaging and secondary processing applications.

Processing Guidelines

  1. LLDPE 7042N is suitable for both blown film and cast film extrusion processes. It offers flexible use across different film production systems.
  2. For optimal performance, it is recommended to operate under medium shear conditions. This helps maintain stable processing and consistent melt behavior.
  3. The resin is suitable for both mono-layer and multi-layer co-extrusion structures. It provides good compatibility in a wide range of film formulations.
  4. LLDPE 7042N can also be blended with LDPE or other LLDPE grades. This allows adjustment of film properties such as strength, flexibility, and sealing performance according to specific application needs.
