The two look similar in a photo and are completely different things. A disposable glass is made to be used once, from a thin, cheap plastic. A reusable glass is made to be washed hundreds of times from a tough one.
Side by side
Disposable vs reusable
| Disposable | Reusable | |
|---|---|---|
| Material | Usually polystyrene (code 6) | Tritan or acrylic (code 7) |
| Looks | Thin and light; good ones look fine from a distance | Close to glass |
| Strength | Snaps if squeezed; two-piece bases can pop off | Tritan survives drops; acrylic can crack |
| Washing | Not meant to be washed | Tritan in the dishwasher; acrylic by hand |
| Cost | Low per glass, every time | Higher once, then free |
| Afterwards | Bin, or recycling where code 6 is accepted | Back in the cupboard |
Which events suit which
Wedding or big reception
Disposable one-piece flutes and glasses, or rented glass for a formal day.
Pool you use all summer
Reusable Tritan. You will use the same set fifty times.
Birthday at home
Reusable if you host often; disposable if it is a one-off crowd.
Festival or public event
Disposable, or flexible reusable cups if the venue asks for them.
Boat and beach house
Reusable Tritan, kept on board or in the house.
Office party
Disposable for a quick clean-up.
Choosing good disposable glasses
- One piece. No base to snap on the morning of the party, and none to fall off during the toast.
- Rigid walls. Very thin glasses crack when a guest squeezes them.
- A real wine shape. A stemmed glass or flute looks like the occasion; a cup looks like a barbecue.
- Test a small pack first. Check the rim, the stem and the base before you order hundreds.
- Order spares. Guests put glasses down and take new ones. Plan about two per guest for a long party.
What happens afterwards
Most disposable glasses are polystyrene, recycling code 6. Many local recycling programmes do not accept it, so check before you assume they will be recycled. If you are hosting more than once a year, a reusable set usually ends up cheaper and leaves nothing to throw away. Reusable glasses do wear out eventually: when a Tritan glass is deeply scratched or cloudy, it is time to replace it.

Disposable or reusable: your questions
What are disposable plastic wine glasses made of?
Usually polystyrene, recycling code 6. Reusable glasses are usually Tritan or acrylic.
Can you reuse disposable plastic wine glasses?
They are made for one use. Washing them is possible but they crack and scratch quickly; a reusable set is the better choice if you host again.
Are disposable plastic wine glasses recyclable?
Polystyrene is not accepted by many local programmes. Check with yours.
When are disposable glasses the right choice?
For a single large event, such as a wedding, a big birthday or an office party, where washing hundreds of glasses is not realistic.
