SMI solutions for Huihuang United Food


Consumption of bottled water on the rise in China

Huihuang United Food chose the integrated system ECOBLOC® ERGON by SMI

The consumption of bottled water is constantly growing in every part of the world. In China, for instance, in the first quarter of 2023 alone, the sales of bottled water increased by 10.9%. In this scenario, the main companies in the beverage industry, such as Huihuang United Food, keep investing in increasingly modern and efficient plants, such as the integrated blowing-filling-capping system ECOBLOC® ERGON by SMI, recently installed in Tianjin for bottling C’estbon brand products in 4.5 L PET containers.

The history of Huihuang United (Tianjin) Food starts in 2011, when the company was founded as a subsidiary of Macau Huiyang International Investment Co., a company belonging to the industrial giant Zhuhai Zhongu for bottling beverages of different brands, such as Coca-Cola and C’estbon.

The cooperation between Huihuang United Food Co. (Tianjin) and SMI started 12 years ago with the purchase of some shrink wrappers for packing bottles under the brand Coca-Cola. The installation of the first 6-cavity stretch-blow moulder for the production of 4.5 and 6 L PET containers under the brand C’estbon dates back to 2015. Thanks to the last investment that led to the purchase of the ECOBLOC® ERGON system, the first supplied by SMI in China, the company was able to increase the production of 4.5 and 6 L formats, which are in high demand by the market, and to further increase the quality and technological profile of the adopted solutions.
