So ensure you check for a ‘Microwave safe’ label on whichever plastic you intend to use. Containers that fall in group number 5 contain Polypropylene plastics and are microwave safe and heat resistant.
Microwave’s Reaction With Solo Cup
Whenever you insert a solo cup into the microwave, the cup’s surface will become extremely hot. Besides, the cup’s bonding will become weak. Then, bisphenol A (BPA) and polypropylene which exists in the plastic, will begin to leach and get into your drink.
These toxic chemicals can interfere with your health even if taken in small quantities. Below are some of the dangers related to BPA ingestion.

At What Temperature Do Solo Cups Start to Melt?
Though plastics start melting at 170 degrees Celsius, the plastic that makes solo cups (Polystyrene branded number 6) begins melting at 100-200 degrees Celsius. Its figure starts deforming at a much lesser temperature than this.
That’s why you’ll notice solo cups start shrinking and distorting their shape once you pour hot drinks into them. The microwave interior becomes hotter than 100 degrees Celsius causing solo cups to melt when microwaving.
What Kind of Cups Are Microwave Safe? Alternatives to Solo Cups)
Plastics contain a certain number, anywhere between one and seven. These numbers enable you to easily identify what type of plastic is used. Specifically, if it’s:
- Microwave safe or not
- Reusable or non-reusable
- Recyclable or non-recyclable
Irrespective of the solo cup variety, they are all placed at number 6. In this cluster, the product encompasses Styrofoam or Polystyrene, so they are not microwave safe.
Others that are not microwave safe are numbers three, six, and seven. Yet products classified as number five are usually polypropylene plastics and are highly heat resistant. Thus they are safe for microwave use.
Even so, these numbers can be somehow confusing. You should know what containers are the best alternatives to solo cups to be secure. Any time you want to warm your drink, consider using:
- Microwave safe glass cups
- Ceramic cups
- Silicon cups
