TITLE: Single Wall Paper Cup With Lid: Specs, Lid Fit and FOB Pricing
SLUG: single-wall-paper-cup-with-lid
META: Order single wall paper cups with lids and the lid is half the risk. Real 8/12/16oz specs, 90mm dome and sip lids, MOQ, and FOB Qingdao price bands per set.
Three cartons came back in July. Not because the cups leaked — because the lids clicked on at the factory, travelled 34 days by sea, and refused to seal on the customer’s espresso machine. The rim had relaxed half a millimetre in the container heat. Nobody checked that on the spec sheet. If you import single wall paper cup with lid sets, this is the failure that shows up last and costs the most.
We convert cups in Qingdao, 2,500 to 3,000 tonnes a year. Here is what goes into the spec.
The cup and the lid are two separate purchases
Most importers treat “cup with lid” as one SKU. It is not. A cup is paper, coating and a rolled rim. A lid is injection-moulded PS or PP cut to a diameter and a wall thickness. They are joined by one number: the rim outside diameter. Get that right and any correct lid fits.
Spec table: the sizes we run most
Indicative tooling. Your mould may differ by a millimetre, so confirm against the drawing.
| Size | Volume | Top dia | Bottom dia | Height | Cup gsm | Lid fit | Lining |
|---|---|---|---|---|---|---|---|
| 8oz | 237 ml | 80mm | 56mm | 92mm | 240–280 | 80mm PS flat/dome | PE 15–18 / PLA 22–26 |
| 12oz | 355 ml | 90mm | 60mm | 112mm | 250–300 | 90mm PS flat/dome/sip | PE 15–18 / PLA 22–26 |
| 16oz | 473 ml | 90mm | 60mm | 135mm | 260–320 | 90mm PS dome/sip | PE 16–20 / PLA 25–30 |
| 20oz | 590 ml | 90mm | 62mm | 152mm | 280–320 | 90mm PS dome | PE 16–20 / PLA 25–30 |
The 90mm trio shares one lid family. Convenient on your shelf, dangerous in your paperwork: switch the 12oz cup to another supplier and keep the old lids, and you find a 0.6mm gap. Staff press harder. The skirt cracks after about 40 cups.
Lid types, and who actually wants each
A flat PS lid suits hot coffee: low profile, stacks well, cheapest, prints cleanly. It dribbles if the drinker sips while walking, since there is no reservoir.
A dome lid gives headroom for whipped and iced drinks. Expect 35 to 60 percent more per lid than flat, and fewer per carton since domes nest loosely.
A sip lid sits between the two, for the coffee-shop look without the dome’s freight penalty. It also generates the most gripes about the flap tearing on first open — check hinge thickness on a sample, not a photo.
A PLA lid looks right next to a PLA-lined cup, but softens near 55–60°C. On hot coffee the skirt loses stiffness within minutes. Plan on paper or CPLA lids, and certify the assembly, not the cup alone.
PE versus PLA lining: the 40–60 percent question
The lining stops the paper drinking the coffee. PE at 15 to 18 gsm is what most of the world buys: reliable at line speed, forgiving on sealing temperature, cheap.
PLA, usually 22 to 26 gsm, is what buyers ask for when their retail customers read the side of the cup. It costs 40 to 60 percent more per cup than PE — roughly one to two US cents on a 12oz — before the practical annoyances: narrower sealing window, slower line speeds, shorter shelf life in humid warehouses. A batch sat through a typhoon week in Ningbo last year and the PLA seam on the bottom disc started to lift. Still usable. The customer’s QC report was not impressed.
PLA buys a story, not a better cup. Cafés without a composting contract do fine on PE at 250 gsm. Institutional buyers — universities, stadiums, municipal tenders — often require PLA, and the premium is a cost of entry. Our certifications page lists which linings we can document to EN 13432 and ASTM D6400.
Heat, condensation and what single wall will not do
No air gap. That is the design. Cheap, light, prints well, and it makes your hand hot.
At 250 gsm with PE and 85°C coffee, expect 45 to 60 comfortable minutes. Below 230 gsm that falls to 20 to 30, faster if the drinker grips hard. Sell a sleeve, or move to double wall. Cold is a separate problem: condensation forms in 10 to 15 minutes and the outside goes slick.
Printing, MOQ and carton economics
Print on 250 gsm and up. Below that, dark solids look washed. Full bleed 3mm past trim, seam clear of text.
| Item | MOQ | Lead time |
|---|---|---|
| Plain cup, PE | 50,000 pcs | 20–25 days |
| Printed cup, 1–2 colours | 100,000 pcs per design | 25–30 days |
| Plain PS lid | 50,000 pcs | 15–20 days |
| Cup + lid mixed carton | 200 cartons | 25–30 days |
Indicative FOB Qingdao bands:
- 12oz, 280 gsm, PE, plain: USD 0.026–0.036 per cup
- 12oz, 280 gsm, PLA, plain: USD 0.040–0.055 per cup
- 90mm PS flat lid: USD 0.010–0.016
- 90mm PS dome lid: USD 0.016–0.024
- 90mm sip lid, printed: USD 0.022–0.032
A 12oz set lands near USD 0.036–0.052 in PE, USD 0.05–0.07 in PLA. Freight moves more than the factory will — a 40HQ to the US West Coast has run USD 2,000 to 8,500 in two years. Quote it monthly.
The fit test we run before shipping
Every lid order gets checked on the line, not in an office.
- Draw ten cups from the first, middle and last hour of the run.
- Fit each lid by hand, then refit after 20 minutes at 60°C.
- Measure rim OD with a calliper; our line holds ±0.3mm.
- Fill 200 cups, lid, invert, shake 10 seconds.
- Photograph failures and send them with the QC sheet.
If cups and lids come from different factories, insist on the same drawing revision.
FAQ
What size lid fits a 12oz single wall paper cup?
Most 12, 16 and 20oz single wall cups use a 90mm rim, so one lid family covers all three. Confirm rim OD on the drawing — some Asian tooling runs 89mm or 91mm and lids will not swap.
Can I use a dome lid on an 8oz cup?
Yes, if the rim is 80mm. Dome lids exist in 80mm PS, though flat lids are more common at that size. A dome adds carton height and little value unless the drink is a frappe.
Are PLA-lined cups with PLA lids home compostable?
No. PLA needs industrial conditions — sustained heat, managed aeration. EN 13432 and ASTM D6400 are written for industrial facilities.
Why do lids pop off after shipping?
Heat. Paper relaxes in a container that hits 50°C and the roll flattens, while the lid was cut for a tighter bore. Put a shipping-temperature clause in the contract and store cartons out of direct sun.
Can you print our logo on the lid too?
Yes. One or two colours on the face, Pantone matched, 100,000 lids minimum per design. Lid printing runs slower than cup printing, adding a few days to the shipment.
Ordering cups and lids as a set from one factory removes most of the fit risk. Send sizes, lining, lid type and destination to our quote desk for a spec sheet, fit-test report and FOB price within two working days.
