Lid Selection Starts with Caliber

A lid should be selected by the cup rim diameter before its appearance or weight. The listed product data covers PET lids for 90-98mm cups, a 90mm sip lid and panda lid, and 119mm injection PP lids. Use the exact caliber from the cup specification, then choose the lid style that fits the beverage and service method.

PET Lid Styles for Different Drinks

The listed PET options support different serving needs. Flat lids fit the 90-98mm range and suit iced coffee and takeaway service. Dome or half-round lids also cover 90-98mm and provide room for whipped cream or desserts. The 90mm sip lid supports strawless service, while the 90mm panda lid is listed for branded specialty drinks.

When an Injection PP Lid Is the Better Match

The listed injection PP options are 119mm lids: single-hole at 6.6 g and phone-holder at 9 g. They should be considered for the matching 119mm cup program rather than mixed into a 90-98mm PET lid plan. Ask the factory to confirm the exact cup model and lid fit before bulk ordering.

Article FAQs

Does a heavier lid always prevent leaks better?

Not by itself. Fit depends first on the exact cup rim caliber and the lid design. Weight is a comparison field, but it does not replace a physical fit check.

Which listed PET lid fits a 90mm cup?

The listed 90mm options include the sip/strawless lid at 3.2 g and the panda lid at 4.5 g. The flat and dome lids are listed for the broader 90-98mm range.

Can a 119mm injection lid fit a 95mm cup?

No assumption should be made from the lid style alone. The listed injection lids are for 119mm, while the PET flat and dome range is 90-98mm. Confirm the exact cup rim and lid specification before ordering.
