Jiangsu Kerui Plastic Industry, located in the Taizhou Port Economic Development Zone in Taizhou, Jiangsu province, has successfully balanced cost efficiency and product quality through the production of lightweight beverage bottle preforms.
WIthin the cost structure of beverage production, preforms are one of the few individual expenses that can be accurately measured. The core of Kerui's lightweight bottle preform solution lies in the need to reduce packaging material costs while not sacrificing product quality.
Kerui preform is formed using high-precision injection molding technology. The neck smoothness, weight, and wall thickness of the preform are specially designed according to the final container requirements. “Lightweight” is not simply about thinning the bottle wall—it involves complex material redistribution based on mechanical analysis.
While ensuring that the grip feel, radial strength, and anti-theft performance of the bottle mouth are not affected, overall weight reduction is achieved by optimizing the wall thickness structure of the bottle mouth and key stress bearing parts.
The clearest benefit offered by lightweighting is the reduction in raw material costs. At the same time, the optimized review grip and visible texture are not compromised, and the quality of the end product remains strong.
Kerui is mainly engaged in the production of plastic packaging products. Beverage bottles are one of the company’s core product lines, accounting for about 30 percent of its annual production capacity. The company has long served Chinese and foreign beverage and purified water production enterprises.
