Can You Microwave GladWare

Microwaving food in plastic containers is a controversial topic. GladWare has been around for years, and it’s still one of the most popular brands on the market. It seems like everyone has an opinion about microwaving their food in GladWare containers, so I decided to do some research. I found that there are both advocates and opponents to this idea. Here’s what I discovered.

Can You Microwave GladWare?

In general, you can microwave GladWare. The manufacturer of GladWare does make a number of microwavable products under the GladWare label, including the popular ‘GladWare container,’ which are plastic containers you can use to contain snacks or other items.

The manufacturer does provide one instruction on microwaving GladWare products. They recommend lifting the corner of the lid when microwaving their containers to vent excess steam. This way, you can avoid a “soggy” mess in your microwave and, on top of that, reduce the chance of the container melting or warping with too much heat.

Although the manufacturer has clearly stated that microwaving GladWare is safe, not everyone holds this same opinion. Many opponents of microwaving GladWare containers like to point out that microwaveable plastics can potentially release harmful chemicals during heating regardless of whether the container is microwave-safe or not.

Another argument is that microwaving will destroy most of the nutrients found in your food.

In my opinion, if the container has passed the FDA’s testing for safety, there is no need to be concerned. The FDA has extensive testing protocols in place when it comes to evaluating food containers.

The FDA requires that manufacturers test food packaging components, including plastic containers, for migration of harmful chemicals to their contents under “worst-case” conditions (e.g., high temperature and/or acidic food). These tests are done with actual food, not just water. Therefore, if the container is deemed safe after testing, you can be assured that it is perfectly safe to microwave GladWare containers.

However, if you are still not sure, you can always go with other options such as glass or ceramic containers. They are both safe options that can be heated in a microwave and do not pose concerns of chemicals leaching into food during heating.

GladWare Microwave Safe Symbol

If you’re unsure whether one of your GladWare products is microwave-safe or not, look for a symbol on the container that looks like five squiggly lines next to one another. If you see this symbol on your product, you can safely microwave it without having to worry the container will melt or warp.

If you do not see a microwave-safe symbol, check the label for additional information or visit the GladWare website to find out more.

Can You Microwave GladWare Lids?

What about microwaving GladWare lids? You can safely put GladWare lids in the microwave. As a matter of fact, GladWare lids are more heat-resistant than regular plastic containers.

However, you need to make sure that you lift up the corner of the lid to allow excess steam to vent as instructed. If you do not lift the corner of the lid, you may find that the steam has nowhere to go but the center of the lid. This can cause warping and sogginess on top of your food.

Different Types of GladWare Products

GladWare launches different products under their GladWare label every now and then. Here is a rundown of each of the products, along with instructions on microwaving them.

  • GladWare Container: can be heated in a microwave without a vented lid or lifted off the corner of the lid to avoid sogginess.
  • Glad Freezerware: should only be microwaved covered with venting corners of the lid up. This will avoid warping.
  • Glad ClingWrap: leave at least 1 inch of space between the food and the ClingWrap. Turn back one corner of the ClingWrap to vent.
  • Glad Food Bags and Glad Freezer Bags: Put the bag on a microwave-safe plate or bowl and open the top of the bag a little (an inch) to vent.
  • Glad Press and Seal: take one corner and pull up to vent.

Tips for Using Gladware in the Microwave

Even though GladWare products are perfectly safe to microwave, there are a few simple guidelines you should follow to make sure you don’t damage your products or risk injuring yourself.

  1. Use only microwave-safe products to heat foods in the microwave. This includes GladWare containers, ovenware, and plastic wraps that are clearly marked “microwave safe.”
  2. Lift one corner of the lid before putting it in the microwave. This will allow excess steam to escape while cooking so you don’t end up with soggy food or risk damaging the container.
  3. Avoid microwaving food high in fat (like bacon) or sugar (like pastries) to prevent the container from melting.
  4. Remember that GladWare containers are still made of plastic, so don’t microwave them for more than a few minutes at a time; otherwise, they may warp.
  5. Let the container sit inside the microwave for a minute to let the steam settle before removing it.
  6. Handle your products with care, especially when trying to remove them from the oven. Use over mitts or hot pads to avoid burning yourself.
  7. Do not microwave empty containers.
  8. Use GladWare containers to defrost and reheat only. Never use them for cooking food in the microwave under any circumstances.
  9. Use low to medium power settings.
  10. Do not use GladWare containers if they are bent, torn, rusted, punctured, or bulging.
  11. Do not use old GladWare containers to microwave food as they may not handle the heat as well as they used to.
  12. Use the correct size GladWare container for your microwave. If it’s too small, food may spill over and create a mess.


So can you microwave GladWare? You can use all of the different types of GladWare products and lids in your microwave and be completely safe as long as the products have a microwave-safe symbol on them and you follow the simple guidelines listed above. If you do not see a symbol, check for additional information on the GladWare website or with an employee at your local grocery store.
