The cups in daily life are made of glass or stainless steel materials that conduct quickly, making it difficult to hold hot drinks directly by hand. Therefore, cup sleeves made of silicone with high temperature resistance have emerged. Common ones in European and American countries include silicone covers for coffee cups and glass milk bottles. Silicone cup covers are mainly used on coffee cups in popular European and American countries, such as the coffee covers on Starbucks restaurants and long coffee covers. Used on company glass cups to display the company's brand and strength. Used on baby product glass cups to protect the delicate hands of infants from burns while drinking milk. It can also be used in industries such as exhibitions, commercial promotion, and business gifts.
