Disposable Cold Cups: Paper or PET for Cold Drinks

Cold drinks put a different load on the cup than hot ones

Tell us the product, the quantity and the delivery country, and a proposal comes back with the full specification attached. Optima Cup is the export brand of Elit Cup: the cups are formed, checked, packed and shipped from one plant in Istanbul, plain or custom printed.

Most buyers begin the search for disposable cold cups from the volume figure: nine ounces, twelve, sixteen. Volume is the easiest number to agree on and the least useful one for predicting how a cup will behave on a busy counter. A cold wall sweats. The drink is poured over ice, so the liquid sits high in the cup rather than in the middle of it. The lid gets pressed on, carried, opened and closed again. None of that is visible in a millilitre figure.

This guide is written from the production side and compares the two materials that actually carry chilled drinks: board with a polyethylene barrier, and clear PET. It stays on measurable differences, because those are the ones you can check in an offer before a container is loaded.

What a buyer actually compares in disposable cold cups

Two offers can quote the same volume and describe two different products. The lines that separate them are always numbers, never adjectives.

• Rim diameter in millimetres, because that is what decides which lid closes.
• Barrier by weight and by the faces of the board it covers.
• Board weight in grams per square metre, quoted size by size.
• Height, which does not follow volume in a straight line.
• Case count, because that is what turns loose pieces into pallets.

Ask for all five together. Any supplier working from a running line has them on hand; a trader assembling an offer from a catalogue usually does not.

Disposable cold cups and the lid family behind them

Rim diameter is the figure that quietly sets your stock list. Across our cold board range the 250 ml cup has a 76 mm rim, the 350 ml cup 80 mm, and the 400 and 480 ml cups both sit at 90 mm. Paper lids follow that pattern: one lid for the 350 ml cup, another shared by the two larger sizes. Move to the clear range and the picture changes completely. Every PET size from 250 ml up to 650 ml is built on the same 95 mm rim and the same 55 mm base, so a single lid family covers the whole ladder: a dome lid with a straw hole, the same dome without a hole, and a strawless sip lid.

For a café with one or two sizes on the menu, that difference is invisible. For a distributor holding stock, it is the difference between three lid references and one. Cold cup lids are also the part customers complain about first, because a lid that pops off on a delivery bike is remembered longer than the cup it came on.

On a chilled wall the barrier works from both sides

A hot cup carries its polyethylene film on the inside face only, and that is enough: the attack comes from the drink. A chilled cup is wetted from the outside as well, by condensation that starts the moment it leaves the fridge. In our catalogue the cold board range is recorded with a 15 gsm polyethylene barrier across both faces of the board in total, for exactly that reason.

This is why hot cups pressed into service as disposable cold cups feel soft at the base by the end of a shift. Nothing failed inside the cup. The board simply drank the condensation running down the outside of it. If an offer for a chilled range repeats the same barrier line used for the hot range, that is worth a question before the order, not after it.

Board weight tells you where a cup gives way first

Grammage is where disposable cold cups are usually thinned down quietly, so it is quoted size by size or it means nothing. Our 250 ml cold cup runs at 250 gsm, the 350 ml at 232 gsm, and the 400 and 480 ml cups at 310 gsm, because a larger cup carries more liquid over a wider unsupported wall. A single grammage quoted for a whole range is the clearest sign the figures were copied rather than measured.

These are the values recorded for our own range and reflect widely used specifications for these sizes rather than a laboratory certificate. Ask any supplier to state grammage in writing, per size, and to say whether the figure is the board alone or the board with its barrier included.

Height and volume do not move together

Two cups of similar capacity can stand very differently on a shelf. Our 350 ml board cup is 118 mm tall on an 80 mm rim; the 400 ml cup is shorter at 106 mm but wider, on a 90 mm rim. In the clear range, 350 ml stands at 110 mm, 400 ml at 123 mm and 500 ml at 138 mm, all on the same rim. A dome lid then adds height on top of that.

Height is the measurement most often left out of an enquiry for disposable cold cups, and it matters in more places than buyers expect: under-counter dispensers, vehicle cup holders, delivery trays, display fridges and the depth of the carrier a courier straps to a bike. Anyone buying iced coffee cups for a drive-through has to check the holder before the menu.

Where clear PET earns its place

Transparency is a functional property, not decoration. Layered drinks, cold brew over ice, bubble tea, fruit teas and smoothies are partly sold by being seen, and a photograph of the drink travels further than a photograph of the cup. Clear pet cups also let staff check the fill level at a glance during service, which shortens the queue.

The same property works against you elsewhere. Condensation is visible on a clear wall, ice looks like it is melting faster than it is, and a drink that separates in the cup separates in public. PET also belongs strictly to chilled service; it is not a hot-drink material at any grammage or thickness.

Where board earns its place

Board takes print around the full wall, and flexographic printing on a cup is one of the cheapest pieces of branding a small chain will ever buy. A printed cup carries a name down the street; a clear cup carries the drink. Printed cold drink cups also hide what a clear wall exposes, which matters for drinks that are honest but not photogenic.

Beyond that, the two materials are handled differently at end of life, and the rules differ by market and change over time. Ask your own importer or waste contractor what applies where you sell, rather than trusting a general claim printed on a brochure.

Cases, pallets and what actually travels

Weight per piece is close: a 480 ml board cup weighs about 12 grams, a 500 ml PET cup about 11.5. Packing is where the two ranges separate. Our 250 and 350 ml cold board cups are packed 2000 to a case, the 400 and 480 ml sizes 1000, and the PET cold range 1000 to a case. A pallet is 20 cases, and the minimum order across the catalogue is three pallets, or 60 cases, which is the figure to plan a first shipment around.

Customs treats the two as different goods. Board cups are declared under heading 4823.69 and PET cups under 3924.10, so duty, paperwork and sometimes market rules diverge before the cups reach your warehouse. If you are buying paper cups wholesale alongside a clear range, ask your broker to price both headings before you split the order.

A checklist before you send an enquiry

• Which drinks are poured over ice, and which are simply served cold?
• How many lid references can your stock list carry without errors?
• Is the drink meant to be seen, or is the cup meant to be seen?
• What is the tallest cup your holders, trays and fridges will take?
• Do you need print now, or a plain cup now and print at the second order?

Answering those five turns a vague request for disposable cold cups into a specification, and a specification is what makes two offers comparable.

Choosing without guessing

Among disposable cold cups there is no single winner between the two materials, and any supplier who declares one is selling what they have. Board wins where the brand has to travel and the drink is ordinary. Clear PET wins where the drink is the product and the lid list has to stay short. Most menus end up with both, split by drink rather than by season.

If you want to see the two ranges side by side, the cold drink paper cup range and the PET cold cup range list the recorded figures size by size, including the 480 ml board cup and the 500 ml PET cup with dome lid used as examples above. When you know roughly what you need, send the product, the quantity and the delivery country through the quotation page and a proposal will come back with the specification written out, plain or custom printed.
