Molding Technologies for 100% Recycled PET
A Sustainable Manufacturing Approach Focused on Resource Efficiency
In line with its sustainability vision centered on resource conservation, AOKI has implemented a unique and advanced project that fully leverages the potential of its technologies. The AOKI eco PROJECT is an innovative recycling and molding system designed to convert used PET bottles back into high-quality PET bottles.
This project has received global recognition for enabling the direct use of 100% recycled PET flakes, obtained from washed and shredded post-consumer PET bottles, in the production of new PET bottles. By moving beyond the conventional limits of recycling processes, the AOKI eco PROJECT brings the principles of the circular economy into practical application within plastic packaging production.
Direct Use of 100% Recycled PET Flakes in Bottle Molding Machines
AOKI Series injection stretch blow molding machines are engineered to produce exceptionally high-quality plastic containers directly from 100% recycled PET flake material. These machines deliver high process stability and consistent product quality, despite the inherent variability of recycled raw materials.
With this machine series, AOKI has developed a molding process that enables the direct use of 100% recycled PET flakes by utilizing its proprietary Direct Heatcon injection stretch blow molding technology. Thanks to this technology, recycled PET flakes can be integrated directly into bottle production without the need for additional intermediate processing steps.
Direct Heatcon technology requires significantly less energy for molding recycled PET pellets or flakes compared to conventional technologies. Processing the preform at an optimal and precisely controlled temperature not only improves energy efficiency, but also ensures the mechanical strength, clarity, and dimensional accuracy of the final product.
In conclusion, the AOKI eco PROJECT and Direct Heatcon technology enable the production of high-quality bottles using 100% recycled PET, offering an advanced molding solution that reduces environmental impact while providing economic benefits for manufacturers. This approach clearly demonstrates that sustainability in the plastic packaging industry is not merely a goal, but a practical and achievable production model.
