Welcome to Wuhan Century Kingxin Co., Ltd. – a professional manufacturer established in 2018, specializing in high-quality disposable paper cups. Our SafeSeam Fully Waterproof Hot Drink Paper Cups are engineered with an innovative seam-sealing technology that eliminates leakage at the weakest point of a traditional paper cup. Designed for demanding hot beverage applications, these cups offer superior structural integrity and complete waterproof protection, ensuring a mess-free experience for your customers. With our ISO9001-certified production and strict quality control, we deliver consistent performance across every batch.
The key differentiator of our SafeSeam cups is the advanced heat-sealing process that bonds the side seam with a triple-layer polymer barrier, creating a permanent, watertight closure. Unlike ordinary paper cups that often suffer from seam delamination or wicking, our cups maintain their integrity even when filled with boiling liquids for extended periods. This makes them the ideal choice for coffee shops, fast-food chains, vending machines, and any business that prioritizes reliability and customer satisfaction.
Key Features & Technical Specifications
- SafeSeam Technology – Proprietary triple-layer heat seal prevents side seam failure, zero leakage tested for over 30 minutes with 95°C water.
- Fully Waterproof Construction – Both interior and side seam are laminated with food-grade polyethylene, making the cup completely impermeable to hot liquids.
- Excellent Insulation Properties – The cup wall thickness (0.3-0.5mm) combined with the PE coating provides natural insulation, keeping beverages hot longer while protecting hands from burns.
- Eco-Friendly Options – Available in PLA (biodegradable) lining upon request, supporting sustainable packaging goals.
- Customizable Printing – Up to 4-color offset printing with high definition graphics, perfect for branding.
- Rigid Rim & Base – Rolled rim design for comfortable drinking and reinforced bottom for stability, no sagging.
