PP/PS Thermoforming Packaging Sheet Extrusion Line

Designed for single-layer PP, PS and HIPS sheet, this single-screw line integrates feeding, extrusion, calendering, haul-off and winding for thermoformed food, consumer and industrial packaging.

Product Advantages

  • The single-screw design and temperature-control process are optimized for PP, PS and HIPS, providing thorough mixing and uniform plasticizing while helping reduce PP sheet cracking and PS sheet yellowing.
  • The line can process virgin materials and qualified recycled materials. Optimized screw geometry, filtration and processing parameters improve the stability of recycled-material production.
  • After adjusting the screw configuration and processing parameters, the line can be used for PP, PS or HIPS sheet production, improving adaptability to different packaging applications.
  • The independently temperature-controlled three-roll calender improves cooling and forming efficiency, surface quality, flatness and thickness uniformity.
  • Siemens PLC and servo control centrally manage extrusion, temperature control, calendering, haul-off and winding for convenient operation and production-parameter management.

Product Details

  • The PP/PS thermoforming packaging sheet extrusion line adopts single-screw extrusion technology. It mainly consists of an automatic feeding system, a single-screw extruder, a hydraulic screen changer, a coat-hanger T-die, an L-type three-roll calendering and cooling unit, haul-off and edge-trimming equipment, and a winding system.
  • Depending on the configuration, the line can produce single-layer PP, PS and HIPS sheets and can process virgin pellets and qualified recycled scraps. The screw geometry, filtration system, die flow channels, roll temperatures and haul-off speed can be adjusted according to the plasticizing temperature, flow characteristics and forming requirements of each material.
  • A PLC touchscreen control system centrally manages extrusion, temperature control, calendering, haul-off and winding. Stable extrusion and three-roll calendering help improve sheet flatness, thickness uniformity and downstream thermoforming performance.
  • Finished sheets are suitable for disposable food containers, fresh and frozen food trays, thermoformed food packaging, dairy and cold-drink packaging, consumer-product inserts, toy inserts and electronic component trays. Sheet width, thickness, output capacity and winding configuration can be customized.
