Performance Features

  1. imodal Molecular Weight Distribution. The bimodal structure delivers an optimized combination of rigidity and toughness, enhancing overall film mechanical performance.
  2. High Mechanical Strength. Films produced with TRB-115 exhibit high tensile strength and modulus, improving load-bearing capacity and durability in end-use applications.
  3. Excellent Puncture and Tear Resistance. HDPE Marlex TRB-115 provides strong resistance to puncture and tearing, helping reduce film failure during handling, transportation, and use.
  4. Superior Processability. Designed for blown film extrusion, the resin offers good bubble stability and a wide processing window, supporting consistent, high-speed production.
  5. Balanced Film Performance. TRB-115 Marlex achieves a well-balanced profile of stiffness, elongation, and impact resistance, suitable for both general-purpose and industrial film applications.

Recommended Applications

Marlex HDPE TRB-115 is widely used in blown film applications, including T-shirt bags and shopping bags, industrial liners and trash bags, agricultural and general packaging films, general-purpose and selected food packaging films.

Processing Recommendations

  • Recommended Processing Method: Blown film extrusion.
  • Demonstrates good thermal stability under typical polyethylene processing conditions.
  • For optimal film quality, processing parameters such as screw design, temperature profile, blow-up ratio, and haul-off speed should be adjusted according to equipment and end-use requirements.
