What Is Tupperware?

Tupperware is the name of a brand producing plastic containers with lids for food storage.

Tupperware containers are one of the most commonly used food storage containers. They are perfect for storing leftover food in the fridge and reheating it in the microwave using the same containers.

Through the years, Tupperware containers have become so popular that “Tupperware” is used as a general term to describe all kinds of plastic food storage containers. 

But the real question is, can you freeze food in Tupperware?

Can You Really Freeze Food In Tupperware?

Freezing is one of the best ways to extend the shelf life of food while preserving its quality, but freezing is only efficient if you choose proper storage containers. 

Most of the containers produced by the brand Tupperware are freezer-safe. Tupperware lookalikes are typically freezer-safe too. 

Is All Tupperware Freezer-Safe?

Not all Tupperware is freezer-safe. A Tupperware container that is not meant for the freezer may crack and break at cold temperatures. 

How To Tell If Tupperware Is Freezer-Safe

If you are not sure whether your Tupperware is freezer-safe or not, check the bottom of the container.

Tupperware that is safe to go into the freezer usually comes with a snowflake sign. Containers with this sign are crafted from durable plastic and can withstand low temperatures. 

If there are no signs on your containers that indicate their features, check the product description provided by the manufacturer. 

Freeze food in Tupperware containers only if you are sure that they are freezer-safe. Otherwise, they may crack or degrade and make the food inside unsuitable for consumption. 

The Benefits And Drawbacks Of Freezing Food In Tupperware

There are both advantages and disadvantages to freezing food in Tupperware.

Here are a few reasons why you should use Tupperware containers to freeze food: 

  • Easy to stack. Tupperware containers are easy to stack not only in the freezer, but also in the cupboards when they are not in use. 
  • Comes in many sizes. Tupperware comes in a range of sizes and shapes. No matter what food you are freezing, you can always find a suitable Tupperware container for it. 
  • Microwave-safe. Most Tupperware containers are now microwave-safe. This means you can freeze, thaw, and reheat leftovers in a single container. 
  • Protective. Unlike plastic bags, Tupperware containers protect the integrity and structure of the products stored in them. The tight-fitting lids of Tupperware also protect the food from freezer burn as well as from absorbing odors from the fridge. 
  • Environmentally friendly. Unlike disposable freezer bags, cling wrap, and aluminum foil, Tupperware containers are reusable. 

Alongside all these great features, Tupperware containers also have drawbacks:

  • They take up more space. While they are easy to stack, Tupperware containers take up more space than freezer bags. Freezer bags filled with food can be flatted and stacked on each other. 
  • You can’t remove the excess air. Unlike freezer bags, you can’t remove the excess air from Tupperware containers.
  • Not all Tupperware is BPA-free. Containers manufactured by the Tupperware brand have been BPA-free since March 2010, but containers purchased before that may contain BPA. Low-quality Tupperware lookalikes may also contain BPA. 

Why Does Tupperware Crack In The Freezer?

Tupperware containers stored in the freezer might crack for a few different reasons:

  • They may crack simply because they are not freezer-safe.
  • A Tupperware container may crack if it is made of a very thin plastic material. 
  • They may break because of the type and amount of food you store in them (food expands when it freezes).

If you have filled a Tupperware container with food all the way to the brim and didn’t leave any room for the food to expand, the container may crack because of the pressure created in it. 

What Foods Can You Freeze In Tupperware?

You can use Tupperware containers to freeze all kinds of raw and cooked foods. They work well for freezing casseroles, stews, pasta dishes, cooked and raw vegetables, fruits, etc. 

Tupperware containers can be used to freeze liquids, too. You can pour smoothies, soups, broth, and other liquid foods into Tupperware containers and freeze them. 

To prevent leakage, make sure to place the containers upright when you first put them in the freezer. Once the food in Tupperware containers is frozen, you can rearrange them however you want to create more freezer space. 

Tips To Freeze Food In Tupperware

There are a few things to consider when freezing food in Tupperware:

  • Make sure that the container you have is freezer-safe.
  • Check the lid to see if it seals tightly. 
  • Choose a container of the right size. Don’t freeze a small amount of food in a large container — doing this leaves too much air in the container, which will cause the food to deteriorate faster. 
  • Remember that the food expands when it freezes. Don’t fill up the container with food all the way to the brim, and don’t press the food trying to fit more of it in a container that is small for the amount you are trying to freeze.  
  • If you are not sure that your container is airtight, wrap a layer of cling wrap around it to protect the food from freezer burn. 

Glass Vs Plastic Tupperware 

The term Tupperware often refers to containers made of plastic. However, you can now get glass Tupperware too — these are food storage containers made of glass! 

Glass containers have their pros and cons. Here’s how they compare to their plastic counterparts:

  • Glass containers are heavier than plastic Tupperware. 
  • Unlike plastic containers that may contain chemicals, glass containers are always food-safe and don’t leach chemicals whether they are frozen or heated. 
  • Glass containers should be handled with extra caution as they will break if you drop them.
  • Unlike some plastic containers, glass containers don’t stain and don’t retain odors. 
  • Plastic Tupperware can be freezer- and microwave-safe. In addition to these properties, glass containers may also be oven-safe. 

Can You Freeze Food In Glass Tupperware?

Similar to plastic Tupperware, you should only use glass containers to freeze food if they are labeled as freezer-safe. 

If your glass containers are not only freezer-safe, but also oven- and microwave-safe, make sure you don’t expose them to drastic temperature changes.

Removing glass containers from the freezer and immediately putting them in the oven or the microwave to reheat food may cause the glass to crack or shatter. 

Freezer-Safe Alternatives To Tupperware

Freezer-safe Tupperware containers work great for freezing food. However, they may not be the best option for you for different reasons.

Here are some of our favorite freezer-safe alternatives to Tupperware!

Freezer Bags

Heavy-duty zip-top bags are the best alternative to Tupperware containers. They are good for freezing all kinds of foods, from raw and cooked vegetables and fruits to meat, stews, and even soups and other liquid dishes. 

Freezer bags are more space-efficient than Tupperware containers. You can also remove the excess air from these bags once you have put the food in. 

If you don’t like the idea of using disposable Ziploc bags and creating so much waste, get reusable freezer bags

Foil

Foil is a good alternative to Tupperware containers for when you are freezing solid foods. Aluminum foil can withstand very low temperatures, plus it doesn’t crack and won’t leak chemicals. 

When wrapping food with aluminum foil, make sure you fully seal it and don’t leave any unwrapped areas as it may result in freezer burn.

You can also freeze food in aluminum foil pans. These pans work well for foods that you will be cooking or reheating in the oven. 

Plastic Wrap

Freezing solid foods in plastic wrap is also an option.

When using it to freeze food, make sure to wrap at least two layers of plastic wrap around the food to keep it airtight. Also, try to get a good quality, food-safe plastic wrap that doesn’t tear easily. 

You can wrap plastic-wrapped food with an additional layer of aluminum foil to protect it from freezer burn. 

Freezing food wrapped in plastic is very space efficient, but the downside of this method is that it only works with solid foods. 

Vacuum-Sealed Bags

If you own a vacuum sealer, freeze food in vacuum-sealed bags. This is the most airtight method for freezing food. It protects food from freezer burn and dehydration. 

A vacuum sealer costs more than Tupperware containers and zip-top bags, but it is certainly worth the money if you freeze large amounts of food.
