Sheet Extrusion

Sheet extrusion is typically used to create sheets with a thickness of 0.5 to 25 mm, and widths of two to nine meters. Polyethylene products fabricated using the sheet extrusion process include:

  • Landfill base and cap liners (2 – 2.5 mm thick)
  • Tunnel liners for road or train tunnels (2, 3, 4 mm thick)
  • Sheets for thermoforming
  • Liners (0.25 – 2 mm thickness)
  • Concrete protective liners and sheets for pipe relining
