LDPE 2420H is a low-density polyethylene resin primarily developed for film extrusion. It is typically manufactured through a high-pressure polymerization process and supplied in pellet form.

The grade offers a balanced combination of processability, flexibility, mechanical strength, and optical performance. These properties support consistent film production and make it suitable for bags, pouches, food packaging films, shrink films, liner films, and other general-purpose flexible packaging applications.

Product Advantages of LDPE 2420H

  • Excellent Processability. LDPE 2420H offers stable melt flow and good extrusion performance, supporting smooth and consistent film production. Its processing characteristics help manufacturers maintain reliable output across a range of operating conditions.
  • Good Flexibility. The grade provides the flexibility required for a variety of thin-film applications. Finished films can withstand bending and handling while maintaining their overall integrity.
  • Balanced Mechanical Properties. A well-balanced combination of tensile strength, elongation, and impact resistance gives the material good durability in flexible packaging applications. It can also be combined with other polyethylene grades to achieve specific performance targets.
  • Good Optical Performance. 2420H LDPE offers good clarity and low haze when processed under appropriate conditions. This makes it suitable for films where appearance and product visibility are important.
  • Reliable Heat-Sealing Performance. Good sealing characteristics support the production of bags, pouches, and other heat-sealed packaging structures. Proper processing conditions can help achieve strong and consistent seals.
  • Good Film-Forming Performance. Its melt behavior and rheological characteristics support stable film formation during extrusion. This helps manufacturers produce films with consistent thickness and uniform appearance.

How to Select the Right 2420H Grade

  • Consider the processing method
  • Check MFR and density
  • Evaluate film requirements
  • Consider additive requirements
