Most of their bags are able to be used in the microwave to heat up food, but it is always better to be safe than sorry.

What is The Maximum Temperature a Ziploc Bag Can Take?

Ziploc uses polypropylene to make their bags because it allows their bags to easily be recycled. Polypropylene will begin to soften at 195 degrees, so it is important to keep your Ziploc bags in temperatures below that.

As mentioned before, we suggest microwaving in 30-second intervals so that you can keep an eye on how hot your bag (and the delicious food inside) is getting.
