The Visual Power of the Rounded Bottom
The U-shape cup (also known as the "fat cup") has redefined the boba and specialty drink market. Its rounded base allows toppings like pearls, jelly, and brown sugar streaks to be showcased without getting stuck in sharp corners. While the shape is iconic, buyers must choose between two very different materials: Thermoformed PET and Injection-Molded PP.

When to Source PET U-Shape Cups
If your menu is focused on iced fruit teas, colorful mojitos, or layered smoothies, PET is the superior choice. Its unmatched transparency makes drink colors pop. The PET U-shape is typically more lightweight and cost-effective than the injection PP version, making it ideal for high-volume cold-drink operations that still want a premium rounded look.
The Advantage of Injection PP U-Shape
Injection-molded PP U-shape cups (like our PP-95U series) are the "heavy-duty" option. They feel more substantial in the hand and can handle hot beverages up to 100°C. For brands that serve both hot milk tea and iced boba in the same format, the PP U-shape provides a consistent premium experience and works perfectly with standard PP sealing films.
