As a professional manufacturer based in Wuhan, China, Wuhan Century Kingxin Co., Ltd. is proud to present our HeatBarrier Single Wall Heat Resistant Cups. These cups combine innovative single-wall construction with advanced heat-resistant coating, delivering a practical and cost-effective solution for serving hot beverages. With over 6 years of manufacturing experience and an annual export value of US$2.5-5 million, we ensure consistent quality and reliable supply to global markets.
Our HeatBarrier cups are designed to keep your customers safe from burns while maintaining the beverage temperature longer. Made from premium food-grade paper and a specialized heat-resistant barrier, these cups are lightweight yet sturdy — perfect for coffee shops, tea houses, convenience stores, and catering services. Available in standard sizes (8oz, 12oz, 16oz) and fully customizable in color and print, they meet diverse branding needs.
Compared to double-wall cups, our single-wall design reduces material usage without compromising thermal protection. This not only offers a more eco-friendly option but also lowers shipping costs — a win-win for your business. Below we detail the key features and specifications.
Key Features & Benefits
Heat Barrier Technology: A specialized coating on the interior resists heat transfer, so the outer surface stays comfortable to hold even with near-boiling liquids.
Single Wall Efficiency: Lighter weight than double-wall cups, reducing material consumption by up to 20% and lowering per-unit cost.
Eco-Friendly Materials: Made from sustainably sourced paper with a water-based coating — recyclable in standard paper waste streams where facilities exist.
Leak-Proof Design: Rolled rim and precision-sealed bottom prevent spills and drips during use.
Custom Branding: Full-color custom printing with your logo, artwork, or marketing message available (flexo or offset printing).
Multiple Size Options: 8oz (240ml), 12oz (360ml), 16oz (480ml) — also available in non-standard sizes upon request.
ISO9001 Certified Production: Our factory follows strict quality management systems, ensuring consistent dimensions, strength, and hygiene.

Frequently Asked Questions
Are these cups truly heat-resistant on the outside? Yes. The interior coating acts as a thermal barrier, significantly reducing heat transfer to the outer surface. You can comfortably hold a cup filled with 90°C liquid without discomfort.
Can I use these cups for cold beverages? Absolutely. While designed for hot drinks, they are also suitable for iced beverages. However, condensation may form on the outside if the drink is very cold.
What is the difference between single wall and double wall cups? Single wall uses one paper layer with a heat barrier coating, while double wall has an extra insulation air gap. Single wall is lighter and more cost-effective, while double wall offers slightly better insulation. Our heat barrier single wall cups provide comparable comfort at a lower price.
Are these cups microwave safe? No. Paper cups with plastic or wax coatings should not be used in microwaves, as the coating may degrade and cause leakage. We recommend transferring beverage to a microwave-safe container.
Can I get custom printing on the cups? Yes. We offer full-color custom printing with your logo or design. Minimum order quantity for custom print is 10,000 pcs, and we can provide artwork guidelines.
What certifications do you have? Our factory is ISO9001 certified. Our cups comply with food contact material regulations (FDA, EU, etc.) upon request. Specific certificates can be shared during inquiry.
What is the minimum order quantity (MOQ)? Standard MOQ is 10,000 pcs per size. For stock cups (without printing), we may accept smaller quantities for trial orders. Please consult our sales team.
How long will the cups keep the beverage hot? The heat barrier coating slows down heat loss, so your drink stays warmer for a longer time compared to regular paper cups. Actual duration depends on ambient temperature and lid usage.
