Features of The PLA Biodegradable Sheet Production Line:
Screw Design: The line features a gradient single-screw design specifically optimized for the melting of polylactic acid (PLA) and corn starch. It also includes a venting option to accommodate the unique properties of these materials.
Process Principle:
Material Feeding: PLA and corn starch are fed into the single-screw extruder.
Melt and Plasticization: The raw materials are melted and plasticized.
Quick-Change Filter Screen: Ensures efficient filtration of impurities.
Extrusion Die: Shapes the material during the extrusion process.
Vertical Triple Extrusion: Enhances the production process for improved sheet quality.
Production Line Components:
Roller Calender: For forming the sheets.
Cooling and Shaping Device: Allows the sheets to cool and solidify.
Edge Trimming Machine: Ensures uniform edges for the sheets.
Pulling Conveyor: Facilitates continuous movement of the sheets.
Automatic Tension Winding: Efficiently winds the finished sheets for storage.
This production line is specifically designed for the efficient manufacturing of biodegradable sheets using sustainable materials like PLA and corn starch.
