Bubble Tea Cup with Seal Lid – 100% Leak-Proof & Customizable

Our Bubble Tea Cup with Seal Lid is a leak-proof packaging solution engineered to address the common challenge of spillage during bubble tea takeaway—whether customers are commuting by car, public transport, or walking. This product combines a food-grade plastic cup (available in PET, PP, or PLA) with a specially designed seal lid, creating a secure barrier that prevents liquid from escaping even when the cup is tilted, shaken, or placed upside down (for short periods). The cup itself is crafted to meet global food safety standards (FDA, LFGB) and features a precision-machined rim with a slight groove (1mm deep) that the lid’s seal fits into, ensuring a tight, consistent closure across every cup. The cup is available in sizes from 400ml to 1L, with a body thickness (1.1-1.2mm) that resists deformation, maintaining the rim’s shape for optimal lid fit. The seal lid is the centerpiece of this system, made from food-grade PP (or PLA for eco-friendly options) and featuring a dual-layer seal: an inner silicone O-ring (FDA-approved) that conforms to the cup’s rim groove, and an outer snap-on flange that locks the lid onto the cup’s rim, preventing accidental detachment. The lid also includes a pre-cut straw hole with a removable silicone plug—when the plug is in place, the hole is fully sealed, and when removed, it fits standard thick straws (12-14mm diameter) with a tight seal around the straw to prevent leaks through the hole. For added convenience, the lid has a small tab on the plug, making it easy for customers to remove, and a raised rim around the straw hole to catch any minor drips. This leak-proof system is essential for bubble tea shops, convenience stores, food delivery services (e.g., Uber Eats, GrabFood), and any business where takeaway is a significant portion of sales. For example, a bubble tea chain in Singapore that generates 70% of its revenue from delivery partnered with us to implement the Bubble Tea Cup with Seal Lid. Prior to using our system, the chain received an average of 20 delivery complaints per day about spilled bubble tea; after switching, complaints dropped to less than 2 per day, and delivery platform ratings increased from 3.5 to 4.8 stars (out of 5). This improvement led to a 25% increase in delivery orders over three months. Another case involves a commuter-focused bubble tea shop located in a busy train station in Tokyo, Japan. The shop’s customers often carry bubble tea onto crowded trains, and the seal lid’s leak-proof design has become a key selling point—customer surveys show that 60% of regulars choose the shop specifically because they trust the cup to not spill in their bags. Customization options for the Bubble Tea Cup with Seal Lid include matching the cup and lid colors to your brand (e.g., a black cup with a white lid, or a brand-specific color for both), as well as printing logos or messages on both the cup (via IML for plastic, water-based inks for PLA) and the lid (via pad printing). The lid’s flat top surface provides ample space for small designs, such as a brand logo or a “Shake Well Before Drinking” reminder. For reusable versions of the cup (made from Tritan or durable PP), the seal lid is also reusable and dishwasher-safe, with the silicone O-ring maintaining its elasticity for up to 500 uses. We offer the Bubble Tea Cup with Seal Lid in both disposable and reusable variants, with minimum order quantities starting at 3,000 units for disposable sets and 500 units for reusable sets. For brands using delivery services, we can also provide additional packaging tips (e.g., placing the cup in a sturdy sleeve) to further minimize spill risk. To test the leak-proof performance, we offer samples that you can fill with liquid and shake or tilt to verify the seal. For pricing, customization details, or to request samples, please contact us. Our team can also provide data on how leak-proof packaging can reduce waste (e.g., fewer spilled drinks that need to be remade) and improve customer loyalty—key metrics for growing your bubble tea business.
