Stainless steel vacuum insulated cups have gained widespread popularity in daily life due to their excellent thermal insulation properties and portability. However, with varying product quality in the market, China has established a series of national standards for stainless steel vacuum insulated cups to protect consumer rights. These standards provide detailed regulations covering multiple aspects including thermal performance, sealing performance, material safety, production processes, quality control, and product labeling.

Stainless steel vacuum insulated cups have become indispensable drink containers in modern daily life due to their excellent thermal insulation and portability. Whether it's a cup of hot tea in winter or a bottle of iced drink in summer, these cups provide perfectly maintained temperatures. However, while enjoying this convenience, we must recognize that stainless steel vacuum insulated cups are not universally suitable - they may react adversely with certain substances, particularly acidic ones.
