Innovative Advances in Corn Starch Degradable Material Production
Shantou Qijia Machinery Co., Ltd. has developed an advanced production line specifically designed for the creation of extruded sheets made from corn starch degradable materials. This series of production lines boasts nine patented technologies and has received recognition from an expert panel from the Ministry of Science and Technology, establishing its technical capabilities as a leader in the Chinese market. The technology not only fills a significant gap within the domestic industry but also meets international standards, earning it accolades such as "National Key New Product" and "National Torch Plan Project." Additionally, it has been honored with the "Green Star" product designation from the China Environmental Protection Industry Association.
The KDFJ-75-298A coextruded twin-screw extrusion sheet unit represents state-of-the-art machinery for the efficient production of starch-based degradable materials. This equipment is particularly adept at producing high-fill corn starch sheets, with a filling capacity ranging from 60% to 85%.
Key features of this machine include exceptional feeding performance, high extrusion efficiency, effective exhaust capabilities, low energy consumption, and consistent discharge volume. It also offers precise mixing, neat trimming, and impressive rolling effects. The equipment is designed for a wide adjustment range, making it ideal for the intricate mixing of various polymer materials into finished sheets.
The KDFJ-75-298A extruder utilizes a high-speed co-rotating gear system, with a main shaft screw and barrel constructed using an innovative modular design. The barrel consists of multiple sections, including two sets of exhaust ports, allowing for flexible configuration based on material and process requirements. This design facilitates a range of processes such as material transfer, mixing, plasticization, shearing, and exhaust, all without the need for machine shutdown. This versatility effectively addresses the challenge of balancing general-purpose and specialized machinery, significantly lowering production costs.
The complete production line for the "Maize Starch Degradable Material Extruded Sheet Machine" leverages rapidly renewable corn starch resources. The resulting cornstarch-based materials can be transformed into various products including food packaging, industrial packaging, disposable tableware, and seasonal decorations. These materials serve as an eco-friendly alternative to traditional EPS foam and PVC products. They are characterized by low production costs, non-toxicity, and biodegradability, breaking down into small fragments within three months and fully decomposing within a year. Environmental assessments conducted by accredited agencies confirm that these products meet stringent ecological standards.
As a groundbreaking environmental material derived from starch rather than petroleum, this innovation addresses the pressing issue of "white pollution" and contributes to alleviating the global reliance on oil. It also presents a significant opportunity for Chinese export packaging products to navigate EU market regulations. Currently, products manufactured through this advanced production line have gained traction in international markets, with successful exports to countries such as Japan, South Korea, Canada, and Singapore, where they have earned the trust and favor of foreign investors.
In summary, the advancements made by Shantou Qijia Machinery Co., Ltd. in the realm of corn starch degradable materials not only promote sustainable practices but also position China as a competitive player in the global market for eco-friendly packaging solutions.
