The Caliber System Explained
In the beverage packaging industry, "Caliber" refers to the outer rim diameter of the cup. To ensure a leak-proof seal, the lid diameter must match the cup caliber exactly. The most common international standards are 90mm, 95mm, and 98mm. Standardizing your shop around one or two calibers can drastically reduce your storage space and inventory costs.

Flat vs. Dome vs. Sipper Lids
Which lid should you choose? Flat lids are cost-effective for standard iced coffees and teas. Dome lids are essential for drinks topped with whipped cream or fruit. Sipper lids (strawless) are becoming the preferred choice in eco-conscious markets to reduce plastic straw usage. At Claropack, our PET lids feature a "Snap-Lock" rim design to prevent accidental pops and leaks during delivery.
