In response to global demand for sustainable manufacturing, Ching Hsing Machinery Co., Ltd. offers a specialized portfolio of sheet extrusion lines designed for the circular economy. With over five decades of engineering experience, we provide robust, high-performance systems that enable producers to effectively process recycled and biodegradable polymers. Our technology empowers businesses to reduce their environmental footprint, lower operational costs, and capture opportunities in the growing green market by transforming materials like post-consumer PET bottle flakes and PLA into high-value, uniform sheets.

Direct Extrusion of 100% Recycled PET Bottle Flakes

Our 100% rPET Sheet Extrusion Line is engineered to directly process post-consumer bottle flakes into premium-quality sheets without compromising on performance. The system integrates a high-efficiency pretreatment stage for secondary crystallization and drying, ensuring optimal material preparation. A precision-engineered screw design facilitates superior melting and compounding of the recycled feedstock. This process, combined with advanced metering and a proprietary T-die, results in PET sheets with exceptional clarity, strength, and high dimensional stability, providing a direct path to producing fully sustainable products.

Maximizing Recycled Content with Multilayer Co-Extrusion

The PET Multilayer Co-extrusion Line offers a strategic approach to resource efficiency and cost reduction. Utilizing advanced ABA co-extrusion technology, this system allows for a high concentration of recycled PET (rPET) in the inner core layer (B) while using virgin PET for the outer layers (A). This configuration maintains food-grade safety standards and a pristine surface appearance, making it ideal for demanding packaging applications. By maximizing the use of recycled content, manufacturers can significantly lower material costs while delivering a product that meets both regulatory and consumer expectations for sustainability.

Biodegradable Solutions with PLA Sheet Extrusion

For applications requiring compostable and biodegradable materials, our PLA Sheet Extrusion Line provides a reliable and efficient solution. Polylactic Acid (PLA) is a plant-based polymer that is 100% decomposable, offering an environmentally responsible alternative to traditional plastics. Our machinery is specifically optimized to process PLA, producing sheets with high transparency and excellent water resistance. These characteristics make the output ideal for a wide range of food packaging, including fresh-food trays, containers, and cups, supporting a complete end-of-life cycle for single-use products.

Engineered for Stability and Customization

The foundation of our sustainable sheet lines is our commitment to engineering excellence and quality control. Ching Hsing Machinery designs and manufactures critical components, including specialized screws and T-dies, entirely in-house. This vertical integration allows us to tailor each system to the unique characteristics of our clients' materials, whether recycled or bio-based. Our machines are renowned for their production stability and precision, ensuring consistent output and minimizing waste. We offer comprehensive customization to integrate seamlessly into your existing facility and production requirements.
