Double Wall Paper Cup

Yongrui's double-walled paper cups offer three specialized categories: double-walled hollow paper cups, corrugated paper cups, and embossed paper cups, available in sizes from 4oz to 22oz. These cups are specifically designed for hot beverages. They offer great heat resistance and active insulation, allowing consumers to enjoy hot beverages safely and conveniently.

Utilizing food-grade paper and an innovative structural design, the unique hollow insulation layer effectively blocks heat conduction. Our field tests show that when holding a 92°C hot beverage, the outer wall temperature of our double-walled paper cups is 40% lower than that of conventional paper cups, ensuring a truly comfortable grip. Our quality control exceeds industry standards: in addition to daily high-volume liquid testing, we also conduct double destructive testing (pressure testing and tear testing) on the cup base, sidewalls, and outer seams to ensure zero leakage under extreme pressure.

The outer surface is specially treated to increase friction and cup rigidity, ensuring a secure grip without the need for a separate sleeve. The rim features a reinforced rolled edge, ensuring smooth, drip-free drinking with freshly ground coffee, hot chocolate, hot milk, and other beverages.

Whether brewed fresh at a boutique cafe, delivered to a high-end hotel, or used for long-distance business trips or outdoor warming in winter, Yongrui's double-walled paper cups ensure consumers enjoy warmth anytime, anywhere.
