The lifted lid also allows the Gladware lunchboxes and food containers to vent off the resulting steam, since the microwave radiation basically interacts with water molecules in order to raise the temperatures of the food and boil them from the inside.

However, not everyone agrees that Gladware is absolutely microwave-safe or even dishwasher-safe. Many people argue against microwaving anything made of plastic

Do Most People Agree That Gladware is Microwave-Safe?

Some believe that microwaving plastic should never be done and your food containers should be limited to ceramic or chinaware and glass. Even the most BPA-free and FDA-approved of plastics still leach off a minute amount of BPA and other plasticizers to your food.

Plastic has a lower heat tolerance compared to ceramic or glass dishes. Therefore, the materials might partially melt and leach off harmful chemicals all over the food they’re supposed to contain when microwaved.

However, as far as the Food and Drug Administration is concerned, any plastic, ceramic, or glass container with the microwave-safe label is considered microwave-safe, which includes Gladware.

How About Glad’s Glassware and Ovenware?

For the most part, even without the microwave-safe label (but it’s better if you get it) anything made of ceramic or glass is considered microwave-safe. An oven-safe ovenware container used for baking lasagna and the like typically can handle the peak temperatures possible with the microwave.

This is the reason why the health-conscious use opal ware, glassware, or ceramics instead of plastic containers from Rubbermaid, Tupperware, Ziploc, and Glad to heat up, cook, or otherwise prepare their food because those items are assuredly 100% BPA-free.

The Exceptions to the Rule

There are exceptions to the rule that glassware is microwaveable. If the glass is too thin—like in the case of wine glasses—it’s not microwaveable. If the glass has a warning against microwaved, it’s not microwaveable. The glassware of Glad are thick enough to take the heat though.

The thinner the glass the likelier it is to suffer from thermal shock or cracking under pressure from sudden temperature changes (a hot plate placed on a sink full of cold water, for example).

Should You or Shouldn’t You Microwave Plastic Gladware?

According to many authorities and experts, the overall safety of plastic containers remains in contentious debate. However, Tupperware, Ziploc, Rubbermaid, and Glad have gotten FDA approval for the micorwaveability of their products.

They also use marketing campaigns to sell the safety of their product, claiming them to be 100% BPA-free when no plastic is that and the FDA only approved of their microwave use because their BPA leaching reach safe levels of minuteness.

The Great Debate on Plastic Microwaveability

Plastics have limits when it comes to microwave ability that ceramic or glass don’t have. This is why if your Tupperware or Gladware have cracks or damage you’re recommended against microwaving food on them because they’ve been compromised and they could emit more BPA in their damaged state.

The microwave heat could also worsen the holes, cracks, and brittleness of such products. The resilience of plastic when facing any heating elements, from microwaves to ovens, has always been in question.
