When you freeze food, you obviously plan to store it to a long period of time. Therefore, a container must be safe enough to allow continuous storage without causing untimely deterioration of smell, taste, and texture of the food. What does that mean on practice? First of all, a container must be air-tight, well-sealed and moisture- and vapor-resistant. Besides, it should be made of rigid material, that will not accidentally break or tear (like a plastic bag). This is especially important if you have a large commercial-grade freezer full of food supplies.

What is Safe Food Storage Containers?

Another important thing you need to consider is safety of the material. Some types of plastic are not safe to freeze food in. Others are only good for one-time use and must be recycled after the contents is gone (i.e. plastic bottles). In any case, plastic undergoes some structural changes when frozen. The effect of these changes on the food we consume, and thus our health, is yet understudied. Glass and ceramics do not release their particles into the food that is inside. Therefore, such containers are perfectly safe for our health.
