Is It Safe? Freezing Food In Tupperware

It is normally safe to freeze food in Tupperware. In fact, freezing food is one of the safest ways to keep food from spoiling or becoming riddled with food-borne illnesses.

Freezing allows for any bacteria or microorganisms that cause illness to become and remain dormant.

Although there are limited safety concerns, freezing food in the wrong packaging causes negative consequences for flavor, color, and consistency. When frozen food gets exposed to air it can cause freezer burn.
