Many of the biggest beverage brands in China are responding to a scenario of rapid expansion by investing in more advanced and efficient production lines. One such instance is in Tianjing, where Huihuang United Food, a major bottler of well-known brands like Coca-Cola and C’estbon, turned to SMI, with which it has long collaborated, for the supply of an integrated blowing-filling-capping system (ECOBLOC® ERGON), the company’s first installation in China, for the purpose of bottling C’estbon brand products in 4.5 L PET containers.
The Huihuang United (Tianjin) Food Co. Ltd.
Huihuang United (Tianjin) Food Company was founded in 2011 as a subsidiary of Macau Huiyang International Investment Co. Ltd., a company belonging to the industrial giant Zhuhai Zhongfu Enterprises Co. The Tianjin-based company, which currently employs about 300 people, has distinguished itself since the beginning of its activity for the ability to manage large productions for third parties; since 2011 it collaborates, for example, with the US multinational Coca-Cola. The first supply of SMI to Huihuang United (Tianjin) Food Company dates back to the same year, with the installation of an SK 802 F shrinkwrapper for packing 0.55 L PET bottles in 6×4, 5×3 and 4×3: this machine is currently installed in one of the two 48,000 bottles/hour production lines of the Tianjin plant. The Chinese company extends over an area of about 100,000 square meters, of which 68,000 square meters occupied by bottling plants. The warehouse area alone occupies an area of 36,000 square meters and allows Huihuang United (Tianjin) Food Co. to store more than 1.5 million packs of C’estbon-branded water, while ensuring its customers a daily delivery of 250,000 packs.
Within the production area, 6 complete lines are currently installed for bottling and packaging various products in various pack formats. The new ECOBLOC® ERGON integrated system recently supplied by SMI, is part of a 6,000 bottles/hour production line for 4.5 and 6 L PET containers branded C’estbon; the new plant is therefore added to the first stretch-blow moulder supplied by SMI in 2015 (in partnership with Sacmi), intended for the production of the same bottle. While the SK 600 F shrinkwrapper supplied in 2013, dedicated to the packaging of 0.35 and 0.55 L PET bottles in film-only, is installed inside the 36,000 bph line.
The bottled water market in China

Among the most important factors in the development of the bottled water sector, it is certainly worth mentioning the constant growth in the size of the Chinese market, both in terms of litres produced annually and in terms of the number of consumers.
Bottled water volumes, increases yearly with a 10.9% increase in the first quarter of 2023, driven by the boom in retail sales. The increase in household consumption has fuelled demand for water in general and in particular in large packaging. In addition, the recovery of tourism, following the lifting of post-pandemic travel restrictions, represented another strong boost to the recovery and expansion of the sector. It is estimated that during 2023 the sales volumes of bottled water will grow annually by 8.7%, a trend that should also be confirmed for the following years due to the increasing propensity of the Chinese population for healthier and more responsible lifestyles for the well-being of society and the environment.

SMI solutions for Huihuang United (Tianjin) Food Co.
The collaboration between Huihuang United (Tianjin) Food Co and SMI began 12 years ago with the purchase of an SK 802 F shrinkwrapper, installed within the production line dedicated to the packing of 0.5 L Coca-Cola bottles in 6×4, 5×3 and 4×3 in film only and with the subsequent supply of an SK 600 F shrinkwrapper installed on the 36,000 bottles/hour line, necessary to increase the production of 0.35 and 0.55 L bottles.
In the field of primary packaging, the collaboration between the Chinese company and SMI began in 2015, with the installation of a 6-cavity stretch-blow moulder for the production of 4.5 and 6 L PET containers for the C’estbon brand. The recent investment in SMI’s first ECOBLOC® ERGON plant in China, has allowed the customer 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 solutions adopted.
Huihuang United (Tianjin) Food and Zhuai Zhongfu are two industrial companies particularly attentive to the environment. Consequently, energy saving and the reduction of carbon dioxide emissions have become one of the pillars of corporate social responsibility, which requires the increasingly massive use of new equipment and technologies designed to combine business efficiency and ecosystem protection.
