Why Polyethylene for Cast Film?

The cast film process offers a fast quench and near-unidirectional orientation, enabling high output rates, excellent gauge control and superior optical properties ideal for packaging applications that depend on clarity, consistency and high-quality appearance.

Key advantages include:

  • Superior optical clarity and high-gloss surface quality
  • Excellent gauge control and film consistency
  • High output rates driven by fast quench and efficient processing
  • Broad portfolio of high clarity LDPE and LLDPE grades for high-speed lines
  • Dedicated technical support for resin selection, processing optimization and productivity gains

Applications

Cast film serves markets where optical clarity, consistent gauge and high-speed convertibility are essential:

  • Food wraps
  • Retail packaging
  • Personal care films
  • Industrial packaging
