The Science Behind 12-Hour Cold Retention Technology

Advanced Double-Wall Vacuum Insulation

The remarkable 12-hour cold retention capability of our premium Stainless Steel Tumblers is primarily attributed to their advanced double-wall vacuum insulation technology. Unlike conventional single-wall containers, these tumblers feature two layers of premium 304 food-grade stainless steel with a vacuum-sealed space between them. This vacuum significantly reduces heat transfer through conduction and convection, creating a highly efficient thermal barrier.

The vacuum-sealed chamber effectively prevents external temperatures from affecting your beverage, whether it's a refreshing iced coffee on a scorching summer day or a hot tea during winter commutes. This sophisticated engineering ensures that ice remains solid for extended periods—often maintaining cold temperatures for the promised 12 hours and sometimes beyond, depending on external conditions and initial temperature.

Superior Materials and Construction Quality

The exceptional performance of our temperature retention technology stems largely from the quality of materials used in manufacturing. Each tumbler in our Classic 20oz Stainless Steel Tumbler Bulk collection is crafted from premium 304-grade stainless steel, renowned for its durability, corrosion resistance, and non-reactive properties. This high-grade stainless steel ensures that no metallic taste transfers to your beverages while providing outstanding structural integrity. The manufacturing process involves precision welding techniques that create a perfect seal between components, eliminating potential thermal leakage points. Additionally, the 8.8×17.2cm dimensions are specifically engineered to provide optimal surface-to-volume ratio for temperature maintenance, striking the perfect balance between portability and thermal efficiency. At just 263g, these Stainless Steel Tumblers remain lightweight despite their robust construction, making them ideal companions for daily use.
