Primary Uses of DOWLEX™ 2645G

DOWLEX™ 2645G can be processed as a standalone resin or blended with LDPE, conventional LLDPE, or metallocene LLDPE grades to achieve targeted film properties. Typical applications include industrial packaging films, heavy-duty sacks, liner films, protective films, consumer packaging, and multilayer coextruded film structures requiring excellent toughness, tear resistance, and durability.

Main Product Features

  • Outstanding Mechanical Performance. The optimized hexene copolymer structure provides excellent tensile strength, impact resistance, and puncture durability, enabling the production of stronger and more reliable packaging films.
  • Excellent Tear Resistance. DOWLEX™ 2645G delivers balanced machine-direction (MD) and transverse-direction (TD) tear strength, helping films withstand demanding handling, transportation, and storage conditions.
  • Superior Toughness. High elongation and excellent flexibility improve resistance to cracking and mechanical stress, contributing to enhanced film durability in heavy-duty packaging applications.
  • Stable Blown Film Processing. The resin exhibits consistent melt strength and excellent bubble stability, allowing smooth processing over a broad operating window while maintaining uniform film gauge and high production efficiency.
  • Attractive Optical Properties. Films produced with DOWLEX™ 2645G offer good clarity, low haze, and high surface gloss, supporting premium packaging appearance where visual quality is important.
  • Flexible Formulation Design. Since the resin is supplied without slip or antiblock additives, converters can optimize additive packages for individual processing conditions and end-use performance requirements.
