Product Advantages of LLDPE SABIC 218NJ

  • Excellent processability. LLDPE 218NJ provides stable bubble formation and a wide processing window in blown film extrusion.
  • Good mechanical performance. The resin offers high tensile strength, outstanding elongation, and good puncture and tear resistance.
  • Balanced toughness and flexibility. It is suitable for thin films requiring durability and impact resistance.
  • Good optical properties. 218NJ produces films with relatively low haze and good surface gloss.
  • Additive-free formulation. Ideal for co-extrusion, lamination, printing, or downstream additive customization.

Typical Applications

LLDPE Sabic 218NJ is widely used in flexible packaging and general film applications, including blown film and cast film, shopping bags and T-shirt bags, liner bags and garbage bags, industrial and consumer packaging films, lamination and co-extruded film structures.

Processing Methods

  1. Primary process: Blown film extrusion.
  2. Recommended melt temperature: Approximately 185–205 °C.
  3. Blow-up ratio (BUR): Typically 2.0–3.0, depending on film thickness and equipment design.
