Jiangsu Purui Machinery Co., Ltd., formerly known as Zhangjiagang Purui Plastics Machinery Co., Ltd., is a national-level high-tech private enterprise dedicated to the R&D, manufacturing, and domestic and international export of complete sets of equipment for recycling waste plastics.
The brand was first established in Zhangjiagang in 2006; in 2021, its production base was relocated to Rugao City, Nantong, Jiangsu Province, marking a brand upgrade and rebranding. The company now operates a self-built factory covering an area of 18,600 square meters, equipped with a machining workshop, an assembly area, a closed-loop environmentally friendly painting booth, a material‑testing and commissioning zone, and storage facilities for raw materials and finished products, enabling fully independent, closed‑loop production across the entire process—from component machining and complete machine assembly to factory‑level debugging and eco‑friendly coating.
With a registered capital of RMB 20 million, the company specializes in ML‑series soft‑material pelletizing machines, single/dual‑screw extrusion pelletizing equipment, PET bottle‑flake pelletizers, fully automatic plastic film and woven bag washing lines, shredders, crushers, and comprehensive auxiliary machinery. Its equipment is suitable for processing various types of waste plastics—including PE, PP, BOPP, BOPET, CPP, OPP films, woven bags, ton bags, fibers, nonwoven fabrics, PET fabrics, spun yarns, mineral water bottles, PC/ABS engineering plastics, and PLA biodegradable waste—enabling resource‑recovery and recycling.

1. Production and Manufacturing Capabilities
The factory premises house five complete machine assembly lines; it is equipped with a total of 30 sets of processing and testing equipment, including laser cutting machines, CNC lathes, milling machines, and more. An independent, enclosed, environmentally friendly paint booth has been constructed, fitted with an exhaust gas purification system. The entire machine casing painting process complies with environmental emission standards, ensuring that the appearance and workmanship of the equipment are controlled at the source.
2. R&D and Intellectual Property Strength
A dedicated R&D team of 15 members specializing in mechanical structure and electrical automation has been established, with annual R&D investment accounting for 10% of the company’s annual revenue. The team continuously iterates on new equipment such as material granulators, plastic washing lines, and automatic slag‑removal filters, while also carrying out specialized optimizations and upgrades for recycling equipment targeting films, woven bags, bottle flakes, and biodegradable plastics. The company holds 23 utility model patents for plastic machinery and masters proprietary core technologies including dense feeding of soft materials, high‑pressure friction cleaning, and fully automated hydraulic slag removal.
3. Production Capacity, Workforce, and Customer Base
The company employs 105 staff members, with over 80 personnel in production and technical roles. Annual sales can reach 100 million yuan, and the facility is capable of delivering 300 complete plastic recycling production lines per year. Its flagship ML soft‑material granulator can process up to 43 tons of waste plastic in a single day.
To date, the company has served more than 1,200 domestic and international clients, with over 450 overseas factory‑building projects under its belt. It possesses extensive experience in customizing mature production line solutions, container loading, coordinating sea freight schedules, and delivering cross‑border projects.
4. Import and Export Qualifications
The company holds all necessary export‑related qualifications, including registration as an operator of foreign trade, registration as a consignor/consignee of import/export goods with customs, and foreign exchange registration.
