1. Flat Plastic Lids with Straw Slot

These lids are flat with a cross-shaped slit for inserting a straw. They're often made from PET or PP (polypropylene) plastic and are widely used in fast food chains and bubble tea shops.

3. Paper Cup Lids
Commonly used for: Eco-friendly hot drinks
In recent years, paper cup lids have grown in popularity as businesses shift away from plastic. These lids are typically made from thick molded paper pulp or PLA-lined cardboard and are compostable in many settings.

So...Which Lid Is Actually the Best for Preventing Leaks?
When it comes to leak-resistance, lock-back lids take the top prize, followed by sip-through lids with stopper plugs. If your business serves a lot of commuters or takeout drinks, investing in higher-grade lids can drastically improve the customer experience (and reduce complaints).
For cold drinks, stick with dome lids without holes or offer reusable plastic lids for cups that work well with reusable straws. Paper lids win points for sustainability but lag slightly in durability.
