R-PET Food-Grade PET Sheet Extruder: Precision Manufacturing Equipment for Converting Recycled Pellets into High-Value Packaging
In the sustainable packaging sector, converting recycled PET bottles into safe, transparent, and high-strength food-grade sheet is a critical step in closing the circular economy value chain. Aceretech's R-PET Food-Grade PET Sheet Extruder is a cutting-edge device tailored for this core process. Designed to process high proportions (up to 100%) of R-PET food-grade recycled pellets, this line utilizes advanced extrusion technology and a sophisticated control system to consistently produce high-quality PET sheet that meets international food safety standards, including those of the FDA and EFSA. It is widely used in high-end packaging applications such as blister packaging, fruit boxes, cake trays, and electronic trays, making it an ideal choice for achieving green production and enhancing product competitiveness.
Core Advantages and Technical Highlights
High-Efficiency Plasticizing System Optimized for R-PET
Processing R-PET pellets places higher demands on the extruder's plasticizing capacity and stability. Our equipment utilizes a high-performance barrier screw and a specially designed barrel to ensure thorough and uniform plasticization of R-PET materials during extrusion. This optimized design not only effectively improves melt plasticization quality, ensuring optimal sheet crystallinity and transparency, but also enables lower melt temperatures while maintaining high production output, thereby reducing energy consumption and saving production costs.
Precise melt metering and stable output ensure superior sheet quality. Thickness uniformity and dimensional stability are key indicators of sheet quality. Aceretech's R-PET sheet extrusion lines are equipped with a high-precision melt gear pump. This pump transforms the unstable melt flow from the extruder into a stable, uniform, and pulsation-free pressure flow, precisely delivering it to the die. This critical feature ensures that the sheet's transverse and longitudinal thickness tolerances are kept to extremely tight limits (e.g., ±1.5%), significantly improving product yield and the success rate of subsequent thermoforming.
Advanced T-Hanger Die and High-Efficiency Three-Roll Calender
We utilize a computer-optimized T-Hanger die to ensure uniform melt distribution across the die lip width, ensuring sheet smoothness. Next, a highly efficient three-roll calender (with top, middle, and bottom rolls) precisely calenders, cools, and shapes the extruded melt sheet. A special flow channel design within the rolls, combined with an efficient temperature control system, ensures a smooth, stress-free surface, uniform crystallinity, and excellent physical properties.
Fully Automated Control and Intelligent Operation
The entire production line is centrally controlled by a Siemens PLC, operated via a large human-machine interface. All process parameters, such as section temperatures, screw speed, melt pump speed, roll speed, and take-off speed, can be precisely set and monitored in real time. This intelligent control system not only simplifies operation and reduces manual skill requirements, but also allows for storage of multiple production recipes, enabling rapid changeovers and significantly improving production flexibility and efficiency.
