What are vacuum sealed cups?
Vacuum sealed cups are specialized containers designed to maintain the temperature of their contents, whether hot or cold, by utilizing a vacuum insulation technique. This means that the space between the inner and outer walls of the cup is devoid of air, creating a barrier that minimizes heat transfer. As a result, these cups can keep beverages hot for several hours or cold for an extended period.
The technology behind vacuum sealed cups often includes high-quality materials such as stainless steel or double-walled glass. These materials provide durability and resistance to flavor retention, allowing users to enjoy their drinks without any metallic taste. It’s this combination of materials and vacuum insulation that makes these cups highly efficient for both hot and cold liquids.
