Wuhan Century Kingxin Co., Ltd. proudly presents the AquaSeam Leak‑Resistant Seam‑treated Beverage Cups – a revolutionary solution designed to eliminate leakage at the most vulnerable point of a disposable cup: the bottom seam. As a dedicated manufacturer with over 6 years of expertise, we combine advanced seam‑treatment technology with rigorous quality control to deliver cups that maintain integrity from first sip to last drop. Whether you serve hot coffee, iced tea, or carbonated sodas, our cups ensure mess‑free handling and customer satisfaction every time.
Our AquaSeam line is the result of continuous R&D investments aimed at solving a common pain point for foodservice operators: drink spills that damage presentation and increase costs. By reinforcing the side‑wall and bottom seam with a proprietary heat‑sealing process, we create a barrier that resists liquid penetration even under pressure. This innovation not only enhances the user experience but also reduces waste and liability for businesses.
Each cup undergoes multiple leak‑testing stations before leaving our ISO9001‑certified facility. We use only food‑grade paperboard sourced from sustainable forestry, with an optional PLA lining for eco‑friendly applications. Our production capacity of 50 million cups per month allows us to serve clients worldwide, from small cafes to multinational chains, with consistent quality and on‑time delivery.
Product Features & Technical Specifications
- Seam‑Treated Technology: A double‑layer heat seal at the bottom joint prevents liquid wicking and leakage, even with hot liquids and vigorous stirring.
- Leak‑Resistant Guarantee: Independently tested to withstand 24 hours of continuous liquid contact without seepage (based on 8oz cups with 95°C water, 15° tilt).
- Material Options: Standard double‑PE coated paperboard (200–300 gsm), or PLA‑coated for compostable requirements. Both are FDA and EU food contact compliant.
- Custom Printing: Up to 6‑color offset or flexo printing, with high‑definition graphics and scratch‑resistant varnish. Minimum order quantity for custom prints: 50,000 pcs.
- Size Range: 4oz (120ml) to 24oz (710ml) available as stock items. Custom diameters and heights supported with a 15‑day tooling lead time.

Frequently Asked Questions
-
Q: What makes AquaSeam cups different from regular paper cups?
A: The key difference is our patented seam treatment. Regular cups use a simple glue or heat seal that can fail under heat or pressure. AquaSeam applies an additional protective layer to the bottom seam, creating a liquid‑tight barrier that prevents leaks even when the cup is squeezed or tipped. -
Q: Are these cups suitable for both hot and cold beverages?
A: Yes, they are designed for a wide temperature range (0°C to 100°C). For extremely hot drinks above 70°C, we recommend using a sleeve for comfort, but the cup itself will not leak or weaken. -
Q: Can I get custom printing with my logo?
A: Absolutely. We offer full‑color custom printing with a minimum order quantity of 50,000 cups per design. Our art department can assist with file preparation and color matching. -
Q: Are the cups environmentally friendly?
A: Our standard cups are made from FSC‑certified paperboard with a water‑based coating. We also offer a PLA‑lined version that is commercially compostable (certified by BPI). Please note that disposal instructions may vary by local facilities. -
Q: What lid sizes are compatible?
A: We design our rims to fit the most common lid sizes: 90mm for 8–12oz cups, 98mm for 16oz, and 112mm for 20–24oz. Lids from major brands such as Solo, Dart, and our own OEM lids fit securely. -
Q: What is the lead time for a standard order?
A: For plain white or natural cups, lead time is 10–15 working days after receipt of payment. For custom printed cups, please allow 20–25 working days for artwork approval, tooling, and production. Rush orders can be arranged. -
Q: Do you provide samples before bulk purchase?
A: Yes, we provide free samples (up to 10 pcs) for you to evaluate the quality. You only need to pay the shipping cost. Contact our sales team with your address and preferred size. -
Q: What quality certifications do you have?
A: Our factory is ISO9001 certified. Our products meet FDA requirements for food contact (21 CFR) and EU regulation 1935/2004. We can provide test reports upon request. Please note that specific certifications like BRC or FSC can be arranged for large volume orders.
