Wuhan Century Kingxin Co., Ltd., established in 2018, is a professional manufacturer dedicated to producing high-quality disposable paper cups. With over 51–100 skilled employees and an annual export value of US$2.5–5 million, we serve markets across North America, South America, Eastern Europe, Southeast Asia, Africa, the Middle East, and Western Europe. Our LeakFort Reinforced Seam Waterproof Paper Cups are designed to solve the common problem of cup leakage, offering a reliable and clean drinking experience for both hot and cold beverages. Whether you need cups for coffee shops, offices, events, or food service, our leak-proof technology ensures no spills and complete customer satisfaction.
The secret behind LeakFort cups lies in our reinforced seam construction. Unlike ordinary paper cups that often leak at the bottom seam after a few minutes, our cups feature a double-layer, heat-sealed reinforced seam that locks in liquids tight. Combined with a food-grade waterproof coating, this cup prevents any moisture penetration, keeping cups sturdy and hands dry. We use eco-friendly, recyclable materials that meet international food safety standards, making LeakFort cups a responsible choice for businesses that value both performance and sustainability.

LeakFort cups are designed with both functionality and aesthetics in mind. The reinforced seam not only prevents leaks but also adds extra strength to the cup’s base, reducing the risk of collapse when the cup is full. The waterproof coating is applied evenly to avoid any weak spots. In internal tests, LeakFort cups remain leak-free for over 4 hours when filled with hot water, outperforming many conventional paper cups on the market. This reliability translates to fewer customer complaints, less mess, and a more professional image for your business.
