Key Features of LDPE 722

  • Excellent Extrusion Performance. This material offers stable melt flow properties, enabling smooth and continuous film extrusion while minimizing issues such as melt fracture or breaks. This ensures high productivity and consistent film quality.
  • Balanced Mechanical Properties. The resin provides a good combination of tensile strength, impact resistance, and elongation, making films durable during processing and end-use applications.
  • Superior Optical Clarity. Films produced from DOW 722 exhibit high transparency and low haze, suitable for packaging that requires excellent visual appeal, such as food packaging and retail bags.
  • Chemical and Environmental Stress Resistance. LDPE 722 demonstrates good resistance to acids, bases, and salts, along with a degree of resistance to environmental stress cracking, making it suitable for a variety of storage and transportation conditions.

Typical Applications of DOW 722 LDPE

  • Packaging films: shopping bags, food bags, shrink films, light-duty packaging
  • Agricultural films: greenhouse covers, mulch films
  • Laminated & co-extruded films: multi-layer and composite films
  • Other: extrusion coatings, protective films, flexible tubing
