Flush Fill vs. Practical Fill

It is important to note that "Flush Fill" (filled to the brim) is slightly more than the "Practical Fill" (usable liquid). For example, a 16oz cup holds about 500ml to the brim, but effectively serves a 473ml (16oz) drink with lid space.

Whether you measure in oz or ml, our factory produces precise molds to meet international standards.

Frequently Asked Questions (FAQ)

Why do some 16oz cups show 480ml and others 500ml?
This is due to the difference between a practical fill (standard 16oz serving) and a flush fill (to the rim). Most international markets use 500ml as the metric equivalent for a large-medium cup.
Are these PET cups suitable for hot beverages?
PET material is specifically designed for cold and room-temperature drinks. It is highly transparent and durable but may deform if exposed to high heat (above 60°C).
Which size is most popular for Iced Coffee?
The 16oz (~500ml) and 20oz (~600ml) are the most common choices for iced coffee and lattes in most global markets.
Are the lids interchangeable between different sizes?
Many of our PET cups are designed with universal rim diameters (like 92mm or 98mm) so that one lid size can fit multiple cup volumes, reducing inventory for our buyers.
Can these cups be recycled?
Yes, PET is one of the most widely recycled plastics globally. Our cups are marked with the "No. 1" recycling symbol for easy sorting and processing.
Do you offer custom printing on these sizes?
Yes, we provide high-quality logo printing services for all the standard oz and ml sizes listed in our guide.
