How Do You Know If A Plastic Container Is Microwave Safe?
To know if a plastic container is microwave safe or not, look for a symbol usually printed on the container. The symbol features stacked square waves or lines that resemble a Wi-Fi signal. If the symbol is present, then the container is safe to use in a microwave. Another way to tell is to check the manufacturer’s instructions or packaging. Some plastics may melt or release chemicals when heated, so it is important to ensure that a container is microwave safe before using it.
