We can assume takeout and delivery will remain the norm for the foreseeable future.

As a result, it will be imperative that you're providing your guests with the same experience at home as they would receive in-house.

When your guests sit down to eat, they want their meal to look and taste great. They'll also want it to be at the right temperature. However, sometimes as hard you try, it is just not possible to control whether your food products will be delivered on time and at the right temperature, or if your guests will choose to enjoy it as soon as they pick it up.

People love convenience and there's nothing easier than being able to pop their meal into the microwave whether it's for a few seconds or minutes to reheat it.

Microwave-safe containers allow your guests to quickly and easily reheat their meal at home without having to transfer containers, dirtying more dishes.

Take-out containers come in a variety of materials including, plastic, foam, aluminum, paper and more, but not all are heat tolerant or safe for use in the microwave. This often has people asking, "Is this container safe for the microwave?"

Many know that microwaving the wrong materials can lead to some serious issues. For example, microwaving certain plastics can cause them to melt and allow certain additives, like BPA, to leach into your foods and beverages.

There's also the risk of microwave damage or fire if aluminum containers are put into the microwave.

With all of the possible dangers, it's critical to the safety and satisfaction of your guests that you provide the right container.

In this article and video, we'll review the most common types of food packaging that are safe for use in the microwave and which should never be put into the microwave.

If there is no symbol, and the container is plastic you can look for the resin code. There are seven resin codes, 1-7, and each number represents a different type of plastic.

Final Thoughts

Selecting the right to-go container is key. It is important that the container you're packaging your to-go foods in can be microwaved so your guests can easily reheat their meal at home, if needed.

Keep in mind temperature tolerance and product usage guidelines will vary by manufacturer.

If you are not sure if the container you are currently packaging your food in is microwave safe, check the product to see if it is labeled, "microwave safe," or if the package contains an image of a microwave. Remember, not all products will state whether they are microwave safe. If this is the case, check with your supplier.

In general, paper products, aluminium, polyethylene terephthalate (PETE), and polystyrene (PS) should never be used in the microwave. On the other hand, high-density polyethylene (HDPE), polypropylene (PP), and molded fiber & bagasse are typically safe to be microwaved.

And while several different factors can cause these types of fires, there's one piece of cooking equipment that's often underestimated when it comes to its potential dangers: the microwave.

In order to help you stay safe -- and keep your kitchen from going up in flames -- here are some reminders about how to properly use your microwave.

15 things to never put in the microwave

1. Paper bags

Paper bags can release toxins that can potentially catch fire.

2. Take-out containers

If the container has any metal, don't put it in the microwave! Metal can easily catch fire in the microwave -- and cause serious damage.

3. Yogurt & butter containers

Plastic containers like yogurt cups and butter containers are meant for one-time use. They aren't made to withstand the high temperatures and heat of a microwave, and if heated they can melt and potentially release chemicals into the food.

4. Eggs

If you want to make hard-boiled eggs, boil them in a pot on the stove. Putting eggs in the microwave will likely just leave you with a huge mess -- after the high temperatures cause them to explode.

5. Styrofoam

This is one of those things people like to test -- thinking, "if I just put it in for a few seconds, it'll be fine..." Nope, don't do it!

Styrofoam cups, bowls, take-out containers -- whatever the type, don't put it in the microwave. Styrofoam is a type of plastic, which doesn't mix well with microwave temperatures.

6. Grapes

They will explode and could catch on fire.

7. Cookware with metal trim

You may have plates or bowls with a pretty metal trim -- and when it comes to whether you should put them in the microwave, remember the word metal. That's a red flag for do not put in microwave!

8. Sauce or dip without a cover

Talk about a mess... Putting any type of sauce or dip in the microwave without a cover (even just a paper towel) will just end up leaving a HUGE mess.

9. Plastic storage containers

Again, the keyword being plastic -- meaning, do not put in the microwave! Certain Tupperware-type plastic containers will have a label if they are microwave safe. If you don't see that label, check the manufacturer's website -- or to be on the safe side, just don't microwave it.

10. Hot peppers

First, they can catch fire. Second, when you open the microwave, the heat can cause the peppers to release chemicals that can burn your eyes -- which sounds great to absolutely no one.

11. Stainless steel travel mugs/bottles

Many people microwave travel mugs not realizing they're made of stainless steel -- which does not belong in the microwave. The stainless steel will not only block the heat from warming whatever's in your mug, but nuking it can also damage your microwave. If the mug is plastic, check the bottom for a
