I love cooking and baking food in the oven. While I have used cast iron pans and glass bowls in the oven, I am not sure if plastic containers can be used in the oven or not.
So I decided to do some research and also share it with my readers here.
Can You Put Plastic in the Oven?
Generally, it’s not recommended to put plastic in the oven.
The reason behind this is that most plastics tend to melt at high temperatures, which can cause chemical reactions and harmful fumes.
However, some exceptions involve specific types of plastics that can withstand heat better than others.
For example, Crystallized Polyethylene Terephthalate (CPET) is a type of plastic that has been specially designed to be heat-resistant.
As long as the temperature stays below 400 degrees Fahrenheit, it’s safe to put CPET in the oven without it melting or releasing harmful chemicals.
When it comes to plastic wrap, experts generally agree that it can be used in the oven at low temperatures, such as when cooking sous vide or when using a browning unit.
However, this is not a practice everybody is comfortable with, and it’s important to follow the manufacturer’s guidelines for using plastic wrap in the oven source.
