The cup you put in a customer's hand is not a neutral decision. It affects heat retention, structural integrity under condensation, portion perception, and whether your brand looks considered or thrown together. Most businesses get caught out by choosing on price alone and discovering the gaps only after the order arrives.
This guide covers the practical differences between cup types, what to prioritise for each drink category, and how to match cup spec to your actual operation rather than guessing.
Why the wrong cup costs you
The visible cost is easy to calculate: cups that leak, collapse, or burn hands get replaced. What is harder to see is the brand cost — a flimsy cup signals a flimsy operation, even when the coffee inside is exceptional.
There are three categories where wrong cup choices cause consistent problems:
- Insulation mismatch. A single-wall cup on a flat white means the customer needs a sleeve or drops the cup. A double-wall cup on a cold brew traps condensation and softens faster than a clear PET alternative would.
- Size creep. Serving a 200ml drink in a 350ml cup looks sparse and increases material cost without adding volume to the drink.
- Generic presentation. An unbranded white cup is a missed brand impression at the point when the customer is most engaged — holding the product.
Fixing these issues is not complicated, but it requires matching the cup to the specific use case rather than buying one style across the board.
Hot drink cups — what actually matters
For any drink served above 60°C, the priority is insulation and structural integrity under heat. A cup that becomes uncomfortable to hold within 30 seconds means a sleeve cost or a customer complaint.
Single-wall paper cups are suitable for drinks served with a sleeve, or at counter service where the customer drinks quickly. They are the lightest and least expensive option but transfer heat to the hand within seconds without additional insulation.
Double-wall paper cups hold heat in the drink longer and keep the outer surface comfortable without a sleeve. The air gap between the walls does the work. For takeaway coffee, this is the standard worth defaulting to — the per-unit cost difference is marginal compared to the sleeve cost and the handling experience.
What to look for in a hot cup specification:
- PE (polyethylene) or PLA lining rated for hot liquid contact
- Wall construction matched to your service model — counter versus takeaway
- Lid compatibility — not all lid rim diameters are interchangeable across cup brands
- GSM (grams per square metre) of the board — higher GSM means a sturdier cup at high temperatures
For hot food — soups, porridge, hot chips — the same double-wall logic applies, with the added consideration of grease resistance. A standard paper cup board is not rated for high-fat content food without a specific lining.

Cold and iced drinks — different rules
Cold cups have the opposite challenge: condensation on the outside weakens the cup over time, and a paper cup that softens in the hand is worse than a flimsy hot cup. The physics are different, so the material choice should be too.
Clear PET cups are the standard for iced drinks, cold brew, smoothies, and milkshakes. PET (polyethylene terephthalate) does not absorb moisture, maintains structural rigidity in cold conditions, and lets the drink be visible — which matters for layered or colour-forward drinks. PET is one of the most commonly recycled plastics in the food service sector, and the recycling rate continues to improve as collection infrastructure expands.
Paper cold cups with a PE lining work for shorter service windows — a drive-through or counter hand-off where the customer drinks within minutes. They are not ideal for extended hold times or for drinks with a lot of ice, which accelerates condensation on the inner wall.
Cup sizing for cold drinks tends to run larger than hot. A 500ml cup is common for iced drinks, smoothies, and bubble tea. Factor in ice displacement: a 500ml cup filled with ice and liquid delivers roughly 300–350ml of actual drink volume depending on ice size and fill style.
If you serve both hot and cold drinks and want to simplify stock management, it is worth mapping your drink menu against cup sizes before ordering. Carrying four cup sizes across two material types is generally more cost-effective than trying to make one cup work across all categories.
Getting the size right
South African foodservice generally works across five core cup sizes: 120ml (espresso or takeaway sauce), 250ml (small hot drink), 350ml (regular coffee or cold drink), 500ml (large cold drink, smoothies, or generous hot drink). These align with standard lid sizing across most supplier ranges.
The common mistake is ordering the cheapest or most available size and adjusting the drink recipe to fit rather than the other way around. This creates portion inconsistency and often leads to a cup that looks underfilled or requires significant overfill to look right.
A useful rule of thumb: leave no more than 15mm of headspace for a hot drink with a lid, and no more than 25mm for a cold drink with ice. Outside of these ranges, the cup looks wrong and customers notice — even when they cannot articulate why.
Putting your brand on the cup
A branded cup is not just marketing — it is the last physical thing a takeaway customer touches. For delivery orders, it may be the only branded element they see.
Custom printing on cups requires minimum order quantities (MOQ). The MOQ varies by print method and cup type — digital printing typically starts lower, while flexographic printing requires larger runs but reduces the per-unit cost significantly at higher volumes. Request a quote to get the right recommendation for your volume.
There are three things worth getting right before placing a branded cup order:
- Artwork format. Cup printing requires vector files (AI or EPS), not JPEGs. If your logo only exists as a raster image, it needs to be redrawn before it can be printed cleanly at cup scale.
- Colour accuracy. Cup board absorbs ink differently to paper or screen. Colours typically print 10–15% darker than they appear on screen. A proper press proof eliminates surprises.
- Bleed and wrap. Cup artwork is not flat — it wraps around a tapered cylinder. The artwork file needs to account for the wrap, or the design will distort or misalign at the seam.
If you do not have print-ready artwork, talk to the team before assuming it is a problem. In most cases there is a workable path — whether that means adapting what you already have or pointing you in the right direction to get there.
If you already have print-ready artwork, you can upload it directly when requesting a quote and skip the design step.
Frequently asked questions
What is the difference between single-wall and double-wall paper cups?
A single-wall cup has one layer of paper board between the drink and the hand. Heat transfers through quickly, making a sleeve necessary for comfortable holding. A double-wall cup has an air gap between two layers of board, which slows heat transfer and keeps the outer surface comfortable without a sleeve. For takeaway hot drinks, double-wall is the practical default unless you are already factoring sleeve cost into your pricing.
Can I use paper cups for cold drinks?
Paper cups with a PE lining can hold cold drinks for short periods, but they are not ideal for extended hold times or drinks with significant ice. Condensation weakens the board over time. Clear PET cups are the better choice for iced drinks, cold brew, smoothies, and any drink that sits in the customer's hand for more than a few minutes.
What sizes do Cups-n-Things stock?
The core range covers 250ml, 350ml, and 500ml across both hot and cold cup categories. Availability varies by material type and current stock levels. The best way to confirm availability for your specific requirement is to request a quote with your size and volume.
Are the cups food safe?
All cups stocked by Cups-n-Things are food-grade and rated for their intended use — hot or cold liquid contact. Material specifications are available on request if you require documentation for compliance purposes.
