The stainless steel vacuum flask is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and then the air in the sandwich between the inner tank and the outer shell is drawn out by vacuum technology to achieve the effect of vacuum insulation.
