Don’t we all love a midnight snack? We sneak out into our kitchen and look for the first snack we can find. But sometimes, you only find vacuum sealed bags. That’s always a bummer. 

Because you don’t know what that bag has, your favourite food or leftovers that you will have to munch on for the night. Whatever it may be, vacuum sealer bags always raise one question. 

Are they microwave safe? Yes, the good old doubt that entangles many minds. Why not eliminate it once and for all? Let us dive into what the theories are and if the claim is as right as the myth goes!

Should You Be Using Vacuum Sealed Bags

You can use vacuum sealed bags. But only for reheating. It is not recommended that you put uncooked food in it or cook the food inside the bag. But you know that, right?

If you don’t then we advise you to only use it for reheating purposes. The microwaves are not safe if used too much. And combined with the plastic, you can get serious effects on your body and health.

Are They Microwave Safe

Some of them are. Some of them are not. The key is to use the ones that will not produce an adverse effect on your body. 

Because let us be clear. Plastic combined with microwave radiation is already an explosive you don’t want to ignite. Hence, there are some vacuum sealed bags that you can use but you need to be sure of what you’re using.

What Vacuum Sealed Bags to Use

Here comes the important question. Are there some bags with special labels on them? What are you supposed to be looking for? Hold on, hold on. We are discussing it.

The first thing you will need to see is that the vacuum bags are free of BPA, plasticizers, and phthalates. What is this person talking about, that is probably the first thought in your head.

Don’t let these words jumble you up. All you need to do is remember these terms. And the next time you go out for groceries, make sure you buy the bags that do not have these terms on its label.

The next thing you will need to do is the opposite of what we have just discussed. Find terms relevant to microwave safety. 

Any packaging bags that you will find at the store will have microwave safe bags. And it will say so on their labels. You will need to look around for such bags but you’ll find them.

Or you can directly find them online at Amazon and other departmental stores. If you are adamant about buying these vacuum sealed bags, then do it the right way.

Is There An Alternative Of It

Now, you may wonder why we are talking of alternatives here. It is just for the people who do not feel safe with the microwave. Or do not have one in the house. 

You do not have to keep using the microwave for heating the sealed bags. There are other ways to eat hot food on a plate. Nothing can beat the warm cheese dripping onto the plate after a quick heat-up, right?

There is an alternative to using the microwave for heating vacuum sealed bags. You can heat them in a pot. 

All you need to do is the following:

  • Preheat a pot filled with enough water that the vacuum sealed bag is dipped completely inside the water.
  • Next, heat the pot and put on the lid over the pot.
  • Let it simmer for a few minutes.
  • Allow the water to come to a boil.
  • Take out the bag as it is heated along with the contents inside it.
  • Remove the plastic and eat up the warm food that you have reheated for yourself.


Now, you’re thinking if these bags are really worth the struggle. Aren’t you? Well, that depends on your lifestyle and taste. But we can assure you that using them the right way will get you what you need. Without the addition of harmful effects on your body. Stay safe and be safe!
