When choosing a thermos, most people focus on insulation performance and appearance. However, the internal liner material determines the safety, taste and service life of the thermos. As a professional thermos manufacturer serving global clients for years, we insist on adopting high-quality food-grade glass as the core liner material for our thermoses, bringing pure and safe drinking experience for every user.

Safety is the top priority for daily drinking containers. Our thermos glass liners are made of high-purity food-grade glass raw materials, with no harmful substances such as lead and mercury. Under high-temperature heating and long-term use, the glass liner will not precipitate any toxic components, nor produce chemical reactions with various drinks. Whether it is boiling hot water, warm milk, fruit juice, or cold beverages, the glass liner can keep the original taste of drinks perfectly, without peculiar smell or flavor mixing.

Different from ordinary glass, our thermos glass material undergoes strict high-temperature tempering and precision processing technology. It features high thermal stability, effectively resisting the temperature difference between extreme hot and cold. It will not crack or deform when switching from holding boiling water to cold drinks, greatly improving the durability of the thermos. Meanwhile, the smooth and dense glass surface prevents scale adhesion and bacterial growth. It is easy to clean and never retains stains, ensuring long-term hygienic use.

We always adhere to strict production and inspection standards. Every batch of glass materials has passed international food-grade safety certifications, fully meeting the usage standards of European and American markets. Combined with our exquisite electroplating process and fine craftsmanship, our glass liner thermoses combine safety, practicality and aesthetics perfectly.
