Established in 2020, Wenzhou Zhongyin Plastic Products Co., Ltd. stands as a distinguished professional enterprise specializing in plastic bottle cap manufacturing. With years of deep cultivation in the industry, it has garnered profound expertise and an impeccable reputation, embodying excellence in both craftsmanship and market trust.
Nestled in Rooms 801 & 805, Building A3, Yuehu Light Industry Industrial City, Pengxi Town, Taishun County, Wenzhou City, Zhejiang Province, the company benefits from a strategically advantageous location. Its prime position ensures seamless logistics for raw material procurement and product distribution, combining geographical convenience with operational efficiency. Spanning 3,000 square meters, the premises feature modern standardized workshops outfitted with cutting-edge production machinery and integrated assembly lines, forming a robust foundation for high-efficiency, premium manufacturing.
The company’s production capacity is a testament to its industrial might. Equipped with 9 high-speed cap-making machines, each capable of churning out approximately 550 caps per minute, it achieves a daily output of 4 million pieces. This robust equipment configuration enables an annual production capacity of up to 500 million plastic bottle caps, solidifying its status as one of China’s leading single-site producers in the sector. Complementing this, four top-tier Guangdong blow molding machines yield 20 tons of PE shrink film daily, with an annual sales volume of 4,500 tons.

Innovation lies at the heart of the company’s ethos, with relentless efforts to elevate technological proficiency. Every plastic bottle cap is imbued with advanced technical features, a result of continuous R&D dedication. For instance, addressing industry pain points—such as poor seismic resistance, rapid aging, high material consumption, hand injuries during opening, and quality inconsistencies in conventional anti-theft caps—the R&D team pioneered a solution. Through meticulous testing and innovative design of anti-slip teeth (optimizing length, angle, and quantity), they developed anti-theft caps that blend aesthetic appeal, structural ingenuity, durability, and superior user experience.
Quality control is executed with uncompromising rigor, adhering to national standards GB/T 17876 - 2010 Packaging Containers - Plastic Anti-theft Bottle Caps and GB 4806.7 - 2016 National Food Safety Standard for Plastic Materials and Products in Contact with Food.

These initiatives ensure unwavering quality assurance and continuous management enhancement.
With products spanning domestic markets and reaching international destinations like Southeast Asia and Saudi Arabia, the company has forged enduring partnerships with numerous global and local industry leaders, earning widespread acclaim and trust. Looking ahead, Wenzhou Zhongyin Plastic Products Co., Ltd. is committed to amplifying investment in R&D, driving the development of lightweight, eco-friendly, and sustainable plastic caps.
