Why the 90mm Injection Lid is the Premium Choice
Unlike thin thermoformed lids, injection-molded lids offer a rigid, secure fit that "snaps" onto the cup rim with high precision. This is critical for delivery-heavy brands. The 90mm caliber is the industry standard for both PET cold cups and hard PP injection cups, making these lids the most versatile accessory in your inventory.
90mm Injection Lid Types Compared
Match your lid choice to your beverage type to prevent spills and improve the customer sipping experience.
| Lid Style | Best For | Functional Advantage |
|---|---|---|
| Funnel Lid | Cream-top / Macchiato | Allows sipping cream and tea together |
| Switch / Heart Lid | Standard Milk Tea | Plug ensures zero leaks during transport |
| Double-Hole Lid | Iced Coffee / Bubble Tea | Accommodates both a straw and a sip-hole |
| U-Mouth Lid | Smoothies / Fruit Tea | Wider opening for chunky toppings |
Functional Design for Delivery Reliability
At Claropack, our 90mm injection lids are engineered with a secondary "Leak-Guard" inner ring. This creates a dual-seal barrier that prevents liquid from seeping through the rim-lid interface even if the cup is tilted during delivery. For boba shops, we recommend pairing these lids with our 90mm hard PP cups for a 100% leak-proof system.
Customization: Beyond Just Black and White
While black and white are the defaults, custom-colored lids (like translucent red, yellow, or pink) are a low-cost way to differentiate your brand. We can produce custom lid colors starting from 1,000 pieces. Adding a branded plug (such as a heart-shaped plug) further reinforces your brand identity with every sip.
