Reusable plastic cups are rigid drinking cups, almost always moulded from food-grade polypropylene, built to be washed and reused rather than discarded. A commercial-grade reusable cup survives 200 or more dishwasher cycles and replaces between 100 and 250 single-use disposables across its working life. UK sizes run from half pint through pint to two pint, with pint being the standard for bar service.
We manufacture them at our factory in Stockton-on-Tees. What follows is the spec detail that decides whether a cup lasts, which is the part most product pages skip.
What are reusable plastic cups made from?
Almost all commercial reusable event cups are polypropylene, recycling code 5. A few suppliers offer rPET or Tritan for specific applications. The differences matter:
Polypropylene (PP). The industry standard. High heat tolerance, so it holds shape through hot commercial wash cycles. Shatterproof. BPA-free and phthalate-free in food-grade form. Slightly translucent rather than optically clear. Recyclable as a single unmixed material. This is what we mould.
rPET. Recycled PET. Clearer than PP, which is why it appears in premium cocktail and wine formats. Lower heat tolerance, so it is less forgiving in a hot commercial glasswasher and tends to have a shorter wash life.
Tritan. A copolyester. Glass-like clarity and very durable, but several times the price of PP. It shows up in hospitality and premium venue applications where the cup is expected to look like glassware.
For a festival, stadium, pub garden or event bar running high volume and heavy washing, PP is the correct choice on every axis except optical clarity. If you specifically need a clear reusable cup for presentation reasons, that is a conversation about rPET or Tritan and a materially different price point.
How many washes do reusable plastic cups survive?
Our cups are rated for 200 or more commercial dishwasher cycles. Three things determine whether you actually get there.
Wash temperature and chemistry. PP tolerates commercial glasswasher temperatures well. Prolonged exposure to aggressive alkaline detergent shortens life. Standard glasswash chemistry is fine.
Print method. This is the one that decides how the cup looks at cycle 150. Surface-applied screen print wears with repeated washing. In-mould labelling fuses the printed label into the cup wall during moulding, so the artwork is structurally part of the cup and cannot abrade off. A screen-printed cup and an IML cup can both be physically sound at 200 washes while looking completely different.
Handling. Cups stacked wet and stored under load can distort. Cups run through a glasswasher on a proper rack do not.
In practice, most cups leave service before they wear out. They go home in bags, get lost in crowds, or get retained as souvenirs. That is not a failure, it is often the point.
What sizes do reusable plastic cups come in?
| Size | Capacity | Common use |
|---|---|---|
| Half pint | 284ml | Halves, tasting sessions, wine, prosecco |
| Pint to line | 568ml at the fill line | Draught beer and cider to legal measure |
| Pint to brim | 568ml at the rim | Soft drinks, cocktails, mixers |
| Two pint | 1,136ml | Concourse and peak-rush bar service |
| Stackable | Varies | Space-limited bars, fast collection |
| Wine | Varies | Hospitality, weddings, corporate |
On the 500ml question, which gets asked often: 500ml is a common European format but is not the UK standard. A UK pint is 568ml, and a cup sold for draught beer service on licensed premises in Great Britain needs to be a UKCA marked pint or half-pint measure, not a 500ml cup. If you have seen 500ml reusable cups, they are typically either European stock or intended for soft drinks where no legal measure applies.
To line versus to brim is the other recurring confusion. A pint to line cup reaches 568ml at a printed line with headroom above for a beer head. A pint to brim cup reaches 568ml at the rim, giving more usable volume for drinks that do not need a head. Full detail is in our guide to what a festival pint is.
Are reusable plastic cups legal for serving beer?
Yes, if the cup carries a UKCA line measure applied at manufacture.
Serving draught beer or cider to a stated measure on licensed premises in Great Britain requires a legal measure vessel. Our pint, half-pint and two-pint cups are UKCA marked at the fill line during production. The mark cannot be added afterward, so unmarked stock that has been printed by a third party is not a legal measure regardless of what is printed on it.
Cups used only for cocktails, soft drinks, or spirits measured separately with a thimble measure do not require the line mark. See our UKCA certified cups page for the full explanation.
Are reusable plastic cups better than disposables?
At event volume, yes, on both cost and waste, and the break-even arrives faster than most buyers expect.
On waste: one reusable cup replaces 100 to 250 disposables. At an event serving 10,000 drinks, that is the difference between a few thousand cups in circulation and 10,000 cups in a skip, plus the waste contract to remove them.
On cost: the unit price comparison is misleading. A 6p disposable costs 6p per drink served, every drink, forever, plus disposal. A 40p reusable cup costs 40p once and then serves hundreds of drinks. Add a deposit scheme at £2 to £3 per cup and unreturned stock is effectively sold well above cost.
On environmental footprint: reusables carry a higher manufacturing footprint that is repaid across roughly three to ten uses. One three-day festival clears it. Our comparison of eco friendly cup types has the detail.
The one scenario where reusables lose is when they are not reused. Ordering dated artwork for a single event and binning the stock afterward is worse than disposables on every measure.
What do reusable plastic cups cost?
Pricing is volume driven, starting from £0.33 per cup at 5,000 units on our Eco Saver tier. Minimum order is 50 cups. At 2,000 units on the same tier, single colour pint to line is £0.35 and full colour is £0.55.
Setup cost is fixed regardless of run length, so small runs carry a higher unit price. That is arithmetic rather than a surcharge. For the full cost breakdown, see what personalised cups cost and our guide to branded plastic cups.
