Why does the actual fill volume sometimes differ from the labeled size?

The labeled volume reflects the total maximum capacity of the cup. For serving drinks with foam, ice, or sealing requirements, we recommend using a cup that’s at least 10% larger than the intended fill volume. For example, to serve a 500ml drink, choose a 550ml (approx. 20oz) cup.

Is 16 oz the same as 2 cups?

Yes. 16 U.S. fluid ounces = exactly 2 cups (473 mL). It's a common size for iced coffee or bubble tea.

How many cups is 20 oz?

20 oz ÷ 8 = 2.5 cups. In mL, it's about 591 mL.

Are bagasse cups safe for hot liquids?

Yes. They are naturally heat-resistant up to 100°C, with no plastic lining and reliable leak prevention.

Can I get lids for bagasse cups?

Yes! We offer compostable lids made from bagasse pulp or CPLA, compatible with all sizes.

Can I customize the cups with my logo or brand color?

Absolutely. We provide OEM/ODM support including full-color printing, embossing, and custom packaging.

What’s 500 mL in oz and cups?

500 mL ≈ 16.9 oz ≈ 2.1 U.S. cups. Perfect for standard cold drink cups.

What Is a Fluid Ounce? How Does It Convert to Cups and mL?

In the U.S. measurement system:

1 US Cup = 8 Fluid Ounces (fl oz)
1 Fluid Ounce = ~29.57 mL

The term “fluid ounce” refers to volume, not weight. It’s used to measure liquids like water, juice, or coffee. For most compostable drinkware applications, fluid ounces are the standard.

Common Conversions

Fluid Ounces (fl oz)	US Cups	Milliliters (mL)
12 oz	1.5	355 mL
14 oz	1.75	414 mL
16 oz	2	473 mL
20 oz	2.5	591 mL
24 oz	3	710 mL
32 oz	4	946 mL

🕵️ Quick Reference: 500 mL ≈ 16.9 oz ≈ 2.1 US cups

Why Choose Bagasse Cups?

🧪 Material & Manufacturing Details

Our bagasse cups are made from sugarcane fiber reclaimed from the sugar industry and, in some formats, blended with bamboo pulp for enhanced strength and flexibility.

No bleach, no plastic coating.
Molded with food-grade tooling and anti-scalding edge cuts.
Designed for both hot (up to 100°C) and cold drinks.

Bagasse is a cost-effective material: over 100 million tons are produced globally each year as an agricultural byproduct, offering both environmental and sourcing advantages.

Bagasse (sugarcane fiber) is an eco-friendly, renewable, and compostable alternative to traditional paper or plastic cups.

Need custom sizes or printed branding? We offer flexible OEM & ODM support for foodservice buyers. See customization options.

Feature	Bagasse Cups	Paper Cups	PLA / Plastic Cups
Compostable?	✔️ Yes (90–180 days industrial)	✖️ Not always (often PE-lined)	✔️ Under special conditions only
Home Compostable	⚠️ Possibly (slower than industrial)	✖️	✖️
Heat Resistance	✔️ Heat-resistant to 100°C+, plastic-free leak barrier	⚠️ May warp or leak	⚠️ PLA deforms with heat
Custom Branding	✔️ Embossed or printed	✔️ Standard printing	⚠️ Limited
Lid Compatibility	✔️ Wide size match	✔️	✔️
Environmental Impact	♻ Low, made from waste fiber	Medium (virgin paper + PE lining)	High (petrochemical origin)

🌱 Bagasse cups are ideal for brands seeking green certifications, zero plastic policy, or participating in plastic bans.
