PLA Biodegradable Sheet Extruion Line

PET twin-screw non-drying exhaust sheet extrusion line-Introduction

>> from Taiwan twin screw design, for the production line with more material back to feed fast, high output, low energy consumption, good plasticization and other advantages;

>> The screw adopts building block structure, multi-combination and wide application. It is not only adjusted in the production of PET, but also suitable for PLA whole biodegradable material and starch-based degradable material;

>> the barrel is provided with double vacuum exhaust to ensure the full discharge of water and gas. the symmetrical thin-walled roller improves the cooling efficiency while improving the production capacity and sheet quality;

>> the host adopts vector closed-loop control system, equipped with melt metering pump quantitative voltage output, more stable operation;

>> The whole machine adopts PLC control to realize automatic control of parameter setting, data operation and feedback, alarm and other functions.

1.PET plastic sheet has the characteristics of high transparency, non-toxic and odorless and environmentally friendly, and is especially suitable for easy recycling of PET in food packaging or other packaging fields. PET is currently an ideal thermoforming packaging material and is widely used in suction packaging, food packaging,hardware packaging, pharmaceutical packaging, electronic white packaging and other fields.

2.However, during the extrusion process, PET's hygroscopic properties may reduce product quality. The single-screw model has efficient vacuum exhaust capability. The biggest advantage over twin-screw extrusion equipment is that the planetary exhaust screw combination structure effectively reduces the viscosity loss ofPET resin and maintains the original toughness of the original sheet.
