A sealed cup does not spill in a delivery bag, stays clean, and tells the customer that nobody has opened it. That is why tea stalls, juice bars, lassi shops and dessert makers are moving from loose lids and plain plastic wrap to a cup sealing machine. Here is what to know before you buy one.
What a cup sealing machine does
A cup sealing machine places a plastic film over the rim of a filled cup or glass and seals it with even heat and pressure. You place the cup under the head, press, and the film bonds to the rim in a couple of seconds. The film is then trimmed or comes cut to size, depending on your setup, and the cup is ready to bag.
Who uses it
- Tea and coffee stalls and cafes that deliver or take away
- Juice, shake and cold coffee bars
- Lassi, buttermilk and curd shops
- Dessert, kulfi and sweet makers who sell in cups
- Bubble tea outlets and any shop that sells drinks in disposable cups
The Cup and Glass Sealer at a glance
| Container size | 95 mm diameter |
|---|---|
| Output | 300 to 400 cups per hour |
| Power | 350 W, single phase |
| Body | Stainless steel |
That output is about five to six cups a minute, which is enough for most stalls even in a busy evening. See the full details on the Cup and Glass Sealer page.
What to check before you buy
- Rim diameter. Measure across the top edge of your cup. The standard model suits a 95 mm cup, and we can make a mould for other sizes.
- Cup material and rim. The rim should be flat, smooth and free of cracks. A damaged rim is the most common reason a seal fails.
- Film. The film has to seal to your cup material. Tell us what your cups are made of and read our film guide.
- Your busiest hour. Count the cups you sell at peak time and compare it with the 300 to 400 per hour output.
Tips for good seals every time
- Leave a small gap between the liquid and the rim. Overfilled cups wet the rim and the film will not stick.
- Wipe the rim if a drop of tea or juice lands on it.
- Keep the cup straight under the head so the pressure is even.
- Seal, then check. Turn a sealed test cup gently on its side to see whether the seal holds before you start a rush.
- Clean the machine at the end of the day with a damp cloth after it cools down.
Is a cup sealer worth it for a small shop?
If you deliver through apps or sell takeaway drinks, spilled orders cost you money and reviews. A sealer is a one-time purchase that also gives your cups a cleaner, tamper-evident look. If most customers drink at the counter, a sealer matters less. If you sell curd, lassi or desserts that travel, it usually pays for itself in fewer complaints and replacements.
