structural-reinforced cup

The double-wall paper cup represents a significant advancement in disposable drinkware, masterfully combining practical engineering with enhanced user experience. Its core innovation lies in the air-insulated cavity created between its two paper layers, which acts as a highly effective thermal barrier. This ingenious design keeps hot beverages at an ideal temperature for longer periods while ensuring the exterior remains comfortably cool and secure to hold, completely eliminating the need for separate cardboard sleeves and reducing material waste.
