SABIC LLDPE 118NJ is a general-purpose film grade linear low density polyethylene. This grade is mainly designed for blown film extrusion and offers an excellent balance of mechanical strength, toughness, and processability. 118NJ is supplied without slip, antiblock, or TNPP additives, making it particularly suitable for formulations requiring additive flexibility, controlled surface properties, or further downstream compounding.

Performance Features of SABIC LLDPE 118NJ

  1. Excellent toughness and puncture resistance. High elongation at break and balanced tensile strength provide superior resistance to tearing and impact.
  2. Good processing performance. Stable extrusion behavior with consistent bubble formation in blown film applications.
  3. Balanced optical properties. Good surface gloss and controlled haze contribute to an attractive film appearance.
  4. Additive-free formulation. The material allows converters to customize slip, antiblock, or other functional additives according to specific end-use requirements.
  5. Versatile blending capability. Sabic 118nj can be easily blended with LDPE or other LLDPE grades to optimize film clarity, stiffness, or sealing performance.

Main Applications

LLDPE 118NJ is widely used in general-purpose flexible packaging and industrial film applications, including:

  • Garbage bags and refuse sacks
  • Carrier bags and shipping bags
  • Industrial liners and protective films
  • Stretch and shrink films
  • Agricultural and covering films
  • Laminated, composite, and co-extruded film structures
  • Frozen food and cold-chain packaging films

Processing Information

  • Processing method: Blown film extrusion.
  • Recommended use: Mono-layer or multi-layer film structures.
  • Blending: Compatible with LDPE and other LLDPE grades for improved bubble stability, sealability, or optical performance.

As the grade contains no built-in slip or antiblock additives, converters may optimize surface behavior by tailoring additive packages to their specific processing and end-use needs.
