There never seems to be a lack of availability when it comes to plastic cups around the kitchen. Plastic cups are an extremely easy and a quick way to enjoy any type of drink. But, for those times where you need to heat up a liquid, be sure to check if that plastic cup is safe to be put in the microwave.
Can you microwave plastic cups? No, avoid microwaving plastic cups for most situations. While microwaving most plastic cups won’t cause a fire, the majority of plastic cups are made with bisphenol A (BPA) and polypropylene which are chemicals that can be harmful for human consumption. Plastic can melt in the microwave and harmful chemicals can be released in either your drink or food.
As mentioned by the FDA, only use plastic containers in the microwave that are labeled for microwave use. If you are unsure about the cup or container, it is best to avoid putting the plastic in the microwave.
Reasons Why It Is Not Safe to Microwave Plastic
The main reason plastic cups should not be microwaved is because of the primary chemicals bisphenol A (BPA) and phthalates. These chemicals are used with plastic to help with the flexibility and shape.
These chemicals can be disruptive to our body’s natural hormones which can cause additional harm to our health.
BPA has been a widely used chemical for almost 60 years. Luckily, modern day society has adapted to a more friendly version of these plastic cups, known as BPA-free plastic bottles. Amazon sells reuseable plastic cups that are microwave friendly. I love how these cups are 26-ounces and dishwasher safe!
Just because the cup isn’t melting, doesn’t mean the plastic cup isn’t still leaching chemicals into your food or drink.
How to Know if a Plastic Cup is Safe to Microwave?
When purchasing plastic cups, most packaging labels will distinguish if they are safe for use in the microwave. If not, you’ll notice that most cups clarify with a statement on the bottom of the cup.
For times where you still can’t locate an answer, search the product online to receive additional information from the manufacturer. Most companies that sell plastic products like to answer this question on their FAQ page.
Plastic cups will usually be safe to use in the microwave if they have a BPA sticker located on them.
