Introduction

The LSI-PET/PLA single screw sheet extruder with dry crystallization system is manufactured by Shantou Longsheng Industry Co., Ltd., a high-tech plastic machinery enterprise in Shantou, Guangdong, China. This machine is designed for producing PET and PLA sheets, which are increasingly in demand for eco-friendly and recyclable packaging.

What Is the Dry Crystallization System?

PET and PLA are hygroscopic materials: before extrusion, they must be crystallized and dried, or the sheet will contain bubbles and lose mechanical strength. Longsheng's integrated dry crystallization system handles crystallization and drying in a continuous, energy-efficient process directly on the production line, which:

  • Simplifies the production workflow by removing the need for separate pre-drying equipment
  • Ensures stable sheet quality with low moisture content
  • Reduces overall energy consumption compared with conventional drying setups

Applications of PET and PLA Sheets

  • Transparent food packaging boxes and cups
  • Milk tea cups and cold-drink cups
  • Compostable packaging made from PLA biodegradable material
  • Blister packaging and thermoformed trays

Why It Matters for Sustainable Packaging

As global brands shift toward recyclable PET and compostable PLA packaging, reliable PET/PLA sheet extrusion equipment has become essential. Longsheng's single screw design offers a practical entry point for factories upgrading to sustainable materials.
