Keep the answer within the selected scope
These three selected offers do not establish a hot-drink setup. The two lid records are for cold-cup families, and the selected PLA straw is explicitly described for cold drinks. A cafe that serves coffee as well as iced drinks should not let the word cafe broaden the product scope. Rim Supply has not verified a hot-lid counterpart among its three current offers, and it does not turn a cold cup code into a hot-use permission.
Do not apply the straw’s maximum to the whole assembly
The EP-ST770 page lists 104°F as a maximum temperature for that straw. That number is not a temperature rating for C-KDL626 or C-KCL90. The full cup, lid and straw arrangement would require applicable evidence for its actual intended conditions. A calculation cannot manufacture that missing documentation. The site therefore does not output a shared maximum temperature or a safe serving range for the assembled components.
Read food-contact conditions as conditions
FDA distinguishes, among other categories, room-temperature filling, refrigerated storage and hot-filled conditions. Those categories explain why a general food-contact statement should not be expanded into every use. The reference is not an FDA certificate issued to these finished selected supplies. The website does not invent a regulator endorsement, a heat-resistance test or a material migration assessment. Current applicable product documentation and independent food-contact review remain pending.
Order a different requirement as a different record
If the actual requirement is hot service, identify the exact cup family and a separately documented lid intended for that service before comparing costs. Keep that request separate from the existing cold-lid case target. Do not substitute based only on a repeated ninety-millimeter number or a similar sip opening. This guide gives a clear boundary for the present selections; it is not an instruction to try a cold accessory with a hotter beverage.
Separate menu categories from packaging permission
A cafe might order supplies for both hot coffee and cold juice in the same purchasing session. That shared business context does not give every accessory both uses. Label these selected records as cold service in the order sheet. A separate hot-service requirement needs a separately documented item and cup relationship. The current tools do not generate a temperature workaround or recommend trying a cold accessory outside its reviewed service scope.
