When choosing a thermos liner, glass and stainless steel are common options, each with their own characteristics and advantages and disadvantages.
1. Glass inner liner
(1) Advantages
Safe and non-toxic, it will not pose any harm to human health. It has good insulation performance, which can effectively maintain the temperature of the beverage without chemical reaction, and can preserve the original flavor of the beverage to the greatest extent possible.
(2) Disadvantages
Relatively heavy in weight and easily fragile, extra caution is required during use to avoid collisions and falls that may cause breakage.
2. Stainless steel inner liner
(1) Advantages
More durable, with explosion-proof and crack resistant characteristics, making it safer to use. The spout design is usually larger, easier to clean, and less prone to mold and rust. Although the insulation effect is slightly inferior to that of a glass liner, it is sufficient for daily consumption. Especially the 316 stainless steel liner, which is considered a surgical instrument grade steel, is very healthy and safe, suitable for users with high material requirements.
(2) Disadvantages
The insulation effect is slightly inferior to that of a glass inner liner.
Therefore, if you value the original flavor and safety of your beverage, have high requirements for insulation performance, and are willing to bear a certain weight and fragility risk, then a glass lined insulated bottle may be more suitable for you. If you value durability and safety more and want insulated bottles to be easy to clean and maintain, then insulated bottles with stainless steel inner liners will be a better choice.
Of course, the specific choice of material for the thermos bottle depends on your actual usage scenario and needs.
