What is a coffee cup sleeve?
A coffee cup sleeve is a protective covering designed to wrap around a hot beverage cup, providing insulation and preventing discomfort from heat. Made from corrugated paper or cardboard, these sleeves create a barrier between the hand and the hot surface, enhancing convenience for customers. They are often customizable and used as an effective branding tool for businesses.
Why do they have bumps on them?
The bumps or ridges on coffee cup sleeves improve insulation by trapping air and minimizing heat transfer to the hand. Additionally, the textured surface ensures a secure grip, reducing the chance of accidental spills.
