According to a report published by the Zhongyan Puhua Industry Research Institute, traditional glass baby bottles accounted for approximately 30% of the overall baby bottle market in 2022. In terms of product segmentation, glass baby bottles constitute the largest sub-market, holding a market share of over 48%.
Early-generation soda-lime glass baby bottles were gradually phased out due to their unstable resistance to thermal shock. In recent years, however, advancements in manufacturing technology have enabled the production of borosilicate glass baby bottles. This development has significantly improved the aesthetic appeal, dimensional precision, and physicochemical properties-as well as the overall safety-of glass baby bottles. High borosilicate glass boasts numerous advantages, including a low coefficient of thermal expansion, high heat resistance, superior strength, and exceptional chemical stability; it can withstand high-temperature sterilization without leaching any toxic substances. To mitigate the inherent fragility of glass, the industry has introduced auxiliary accessories-such as external plastic protective sleeves-to enhance the bottles' resistance to breakage and scalding.
The market landscape has evolved into a competitive environment featuring numerous well-known brands. In 2011, amid concerns regarding the safety of Bisphenol A (BPA), China banned the import and sale of baby bottles containing BPA; this regulatory measure subsequently fueled a surge in sales for glass baby bottles. In 2020, the Standardization Administration of China issued the mandatory national standard GB 38995-2020, titled *Baby Bottles and Nipples for Infants and Toddlers*. Implemented on November 1, 2021, this standard establishes explicit requirements for glass baby bottles regarding thermal shock resistance, water resistance, internal stress levels, and mechanical impact strength.
Looking ahead, the direction of technological research and development within the baby bottle industry is expected to focus on the exploration of novel, eco-friendly materials. Third-party testing has demonstrated that glass materials exhibit superior chemical safety compared to most plastic materials when exposed to high temperatures, in addition to offering a longer service life.
