BLOWPLAS TECHNOLOGY CO., LTD.

Blowplas Technology Co., Ltd. has nearly 20 years of expertise in One-Stage Injection Stretch Blow Molding (ISBM) technology, specializing in high-value, diversified, and low-volume PET bottle and container production for global packaging markets. PET is widely recognized for its non-toxic properties, high impact resistance, and excellent transparency, offering a glass-like crystalline appearance superior to PVC, PE, and PP. As a result, PET bottles and containers have become a dominant solution in cosmetics, pharmaceutical, and food packaging industries. Blowplas continues to innovate around this material trend by delivering highly efficient and flexible manufacturing solutions. Blowplas’ one-stage PET injection stretch blow molding machines are designed for 10–500cc containers, serving a wide range of applications including: Cosmetics, lotions, and shampoo bottles Mouthwash and detergent containers Baby feeding bottles Pharmaceutical and infusion bottles Food, condiments, and alcoholic beverages PET cans and industrial containers Supported materials include PET, PET-G, PLA, PEN, PP, PP-SU, TRITAN, and PC, enabling manufacturers to address diverse product designs and regulatory requirements. Core Technology & Machine Advantages The BT-S and BT-J series feature Blowplas’ patented 2-station servo rotary table with side-blow system. After injection, the servo table rotates 180 degrees to transfer the preform to the side-blow station for stretching and blowing, then returns to the ejection position. This innovative design: Minimizes mold quantity and tooling investment Provides ample space for maintenance and servicing Allows easy integration of optional devices such as gate trimmers and product conveyors Enhances process stability and product quality The BT-S model is ideal for standard small containers with short cycle times, while the BT-J model, with higher injection clamping force, is specifically designed for wide-mouth jars and containers. The Value of the One-Stage Process At the heart of Blowplas technology is its direct temperature control (in-mold preconditioning), which utilizes residual heat from preform injection to perform stretching and blowing without reheating. Compared to two-stage systems, this approach offers: Lowest overall machine investment Complete processing on a single machine, reducing labor costs Fewer surface defects and higher product value No contamination during production No burrs and no recycling issues Highly accurate and consistent neck dimensions Integrated Solutions You Can Rely On Beyond machinery manufacturing, Blowplas provides comprehensive mold design and manufacturing capabilities, delivering one-stop solutions from machines and molds to final container production. With reliable performance, competitive pricing, and a global sales and service network, Blowplas Technology Co., Ltd. stands as a trusted long-term partner for packaging manufacturers worldwide.
