Overview

The DSI-PP multilayer co-extruded sheet extruder is one of the recommended products of Shantou Longsheng Industry Co., Ltd., a plastic machinery manufacturer founded in 1998 in Shantou, Guangdong, China. This extrusion line is designed to produce multilayer polypropylene (PP) sheets that serve as raw material for thermoforming machines and cup making machines.

Why Choose Multilayer Co-extrusion?

Multilayer co-extrusion combines different polymer layers in a single sheet, allowing manufacturers to:

  • Optimize material costs by using recycled or lower-cost core layers between virgin outer layers
  • Improve performance, such as better stiffness, barrier properties, and surface finish
  • Meet food-contact requirements with a food-grade outer layer and an economical core

Typical Applications

Sheets produced by the DSI-PP line are widely used for:

  • Milk tea cups, water cups, and ice-cream cups
  • Chocolate package boxes and candy boxes
  • Fast-food containers and other plastic packaging

Longsheng's Extrusion Product Family

In addition to the DSI-PP multilayer line, Longsheng manufactures the LSI-PET/PLA single screw sheet extruder with a dry crystallization system and the SI-PE single sheet extruder with three-roll separately driven design.
