2. Size & Capacity Guide
Packaging sizes vary by region and standard. Cup Source stocks industry-standard capacities with precise fill lines to minimize waste and prevent spills.
Common Cup Sizes
- 8oz / 240ml: Ideal for espresso drinks, tasting portions, and kid-sized servings.
- 12oz / 350ml: Standard hot coffee and tea size. Most cost-effective for volume sales.
- 16oz / 470ml: Popular for iced beverages, smoothies, and premium lattes.
- 20oz / 590ml: Large format for cold brew, bubble tea, and specialty frappes.
Single vs Double Wall
Single-wall saves cost and space. Double-wall adds 30% insulation, reducing sleeve needs and improving customer comfort with hot drinks.
Graduated Fill Lines
Our cups feature laser-etched or printed fill lines to ensure consistent portioning and accurate pricing.
Nesting & Storage
Standard taper rates (15%–20%) allow efficient stacking. We recommend storing in climate-controlled environments to prevent warping.
3. Lids, Sleeves & Accessories
Compatibility is critical. Mismatched lids cause leaks, increase waste, and frustrate staff. Always verify rim diameter and taper rate before bulk ordering.
Lid Types & Use Cases
| Lid Type | Material | Best Application |
|---|---|---|
| Flat Hot Lid | PP | Hot coffee, tea (sip hole or sealed) |
| Vented Iced Lid | PP | Iced drinks, smoothies, bubble tea |
| Dome Lid | PP/PS | Boba, whipped cream toppings, desserts |
| Slam Lid | PE | Takeaway travel, spill-resistant delivery |
Sleeves & Coasters: Recycled paper sleeves add branding real estate and protect hands. Available in standard wrap-around or custom die-cut shapes. We recommend 12pt recycled board for durability.

6. Frequently Asked Questions
PLA (Polylactic Acid) is derived from corn starch or sugarcane and breaks down in industrial composting facilities. Regular PET plastic is petroleum-based and designed for long-term recycling. PLA is not recommended for hot beverages above 55°C as it may soften.
Yes. We provide a complimentary sample kit containing your most relevant sizes, materials, and lid types. Shipping is typically 2–4 business days within your region.
Absolutely. Our warehouse supports consolidated pallets. Just ensure materials are compatible with your storage conditions. Custom branding orders require separate production runs but can be scheduled to ship together.
