Performance Advantages of Marlex TR-131

  • Outstanding Impact Strength and Tear Resistance
    Marlex TR-131 provides excellent resistance to puncture and tear propagation, ensuring durability in demanding film applications such as carry-out bags and refuse sacks.
  • Soft Film Feel and Flexibility
    Films produced from Marlex TR131 exhibit a noticeably softer hand feel compared to conventional HDPE films, improving usability and consumer perception.
  • Excellent Processability
    Designed for blown film extrusion, offering stable melt strength and bubble stability along with a wide processing window. These characteristics enable efficient processing, reduced downtime, and consistent film quality.
  • Versatile Blending Capability
    MDPE Marlex TR-131 can be blended with high molecular weight HDPE or other polyethylenes to increase stiffness, enhance mechanical performance, and optimize cost-performance ratios.
  • Superior Low-Temperature Performance
    With a very low brittle temperature, films retain flexibility and toughness even under cold storage or outdoor conditions.

Main Applications of MDPE TR131

  1. Flexible Packaging: T-shirt bags, retail and shopping bags, trash and refuse bags
  2. Industrial Packaging: Industrial liners, protective packaging films.
  3. Agricultural and Specialty Films: Agricultural films, surface protection films.

Processing Methods

  • Blown film extrusion
  • Co-extrusion film processes
  • Blending with HDPE or LLDPE
