Can you freeze Tupperware?

Tupperware containers are widely used for storing food at room temperature and in the refrigerator. However, when it comes to freezing food, many people wonder if Tupperware is a suitable option. This article explores the topic of freezing food in Tupperware containers, discussing their freezer-safe properties, how to determine if a Tupperware container is suitable for freezing, the pros and cons of using Tupperware for freezing, and alternative options for freezing food.

What is Tupperware?

Tupperware is a well-known brand of plastic containers with lids designed for food storage. Over the years, Tupperware containers have become synonymous with all types of plastic food storage containers. These containers are often used to store leftover food in the refrigerator and reheat it in the microwave using the same container.

Freezing food in Tupperware

When it comes to freezing food in Tupperware containers, it is important to note that not all Tupperware containers are freezer safe. Freezer-safe Tupperware containers usually have a symbol or statement on the packaging that confirms their suitability for freezing. It is important to make sure that the Tupperware container has an airtight lid when freezing food.

How to identify freezer-safe Tupperware

To determine if a Tupperware container is freezer safe, check the bottom of the container for symbols or marks. Freezer-safe Tupperware containers often have a snowflake symbol, indicating that they are made of durable plastic that can withstand low temperatures. In cases where there are no signs on the containers, the product description provided by the manufacturer can provide insight into their freezer-safe properties.

The pros and cons of freezing food in Tupperware

There are advantages and disadvantages to freezing food in Tupperware containers. Understanding these can help individuals make informed decisions about using Tupperware for freezing.

Advantages

  • Easy to stack: Tupperware containers are designed for easy stacking, not only in the freezer, but also in cupboards when not in use.
  • Versatile sizes: Tupperware containers come in a variety of sizes and shapes, making it easy to find the right container for different types of food.
  • Microwave safe: Most Tupperware containers are microwave safe, so you can conveniently freeze, thaw and reheat leftovers in one container.
  • Protective: Tupperware containers protect stored food by preserving its integrity and texture. Tight-fitting lids also protect food from freezer burn and prevent it from absorbing odors from the refrigerator.
  • Environmentally friendly: Unlike disposable freezer bags, plastic wrap and aluminum foil, Tupperware containers are reusable, making them a more sustainable option.

Disadvantages

  • Space consumption: Tupperware containers take up more space than freezer bags. Freezer bags can be flattened and stacked to optimize storage space.
  • Limited air removal: Unlike freezer bags, it is not possible to remove excess air from Tupperware containers, which can affect the quality of frozen food.
  • BPA concerns: While the brand’s Tupperware containers have been BPA-free since March 2010, older containers may still contain BPA. Some lower-quality Tupperware alternatives may also contain BPA, posing potential health risks.

Why Tupperware cracks in the freezer

Tupperware containers stored in the freezer can crack for several reasons. Thin plastic materials used in certain Tupperware containers can cause cracking when exposed to low temperatures. In addition, the type and amount of food stored in the containers can contribute to cracking. If a Tupperware container is filled to the brim without leaving room for the food to expand as it freezes, the pressure created inside the container can cause it to crack.

Foods that freeze well in Tupperware

Tupperware containers can be used to freeze a wide range of raw and cooked foods. They are great for freezing casseroles, stews, pasta dishes, cooked and raw vegetables, fruit, and more. Tupperware containers can also hold liquids such as smoothies, soups, and broths. It is important to make sure the containers are placed upright to prevent leaks, and once the food is frozen, they can be rearranged to make the most of the space.

Tips for freezing food in Tupperware

When freezing food in Tupperware containers, several considerations can help ensure the best results:

  • Choose freezer-safe containers: Make sure the Tupperware container is specifically labeled as freezer-safe and that the lid seals tightly.
  • Choose the right container size: Use a container that fits the amount of food you want to freeze. Leaving excess air in the container can cause freezer burn and affect the quality of the food.
  • Allow for food expansion: Leave some headspace in the container to allow for food expansion during freezing. This prevents the container from rupturing due to pressure buildup.
  • Label and date containers: To keep your food fresh and organized, label each container with the contents and freezing date. This makes it easy to identify and use the oldest frozen items first.
  • Close containers properly: Make sure lids are securely fastened to maintain airtightness and prevent freezer burn.
  • Use a double layer for liquids: When freezing liquids such as soups or sauces, consider using a double-layer approach. Place the filled container inside a larger container to prevent leakage during freezing.
  • Thawing Frozen Food: When thawing frozen food stored in Tupperware containers, it is recommended to thaw the food in the refrigerator to maintain quality and minimize bacterial growth.

Alternatives to Tupperware for freezing

While Tupperware containers are a popular choice for freezing food, there are alternatives:

  • Freezer bags: Plastic freezer bags are a convenient and space-saving option for freezing food. They allow for easy removal of excess air and stack efficiently in the freezer.
  • Glass containers: Glass containers with airtight lids are another alternative to Tupperware. They are freezer safe, environmentally friendly and do not contain potentially harmful chemicals like BPA.
  • Tinfoil and freezer paper: Wrapping food tightly in aluminum foil or freezer paper can help prevent freezer burn. However, these options may not be as convenient for stacking and organizing in the freezer.

Conclusion

In summary, Tupperware containers are generally suitable for freezing food, provided they are labeled as freezer safe and have airtight lids. They offer several advantages, such as easy stacking, versatile sizes, and microwave safety. However, it is important to consider the drawbacks of limited air removal and potential BPA concerns. Understanding why Tupperware cracks in the freezer and following best practices for freezing food in Tupperware can help ensure optimal results. In addition, alternative options such as freezer bags, glass containers, and aluminum foil can be considered based on individual preferences and needs. Ultimately, choosing the right storage method for freezing food will help preserve its quality and extend its shelf life.
