The Do's and Don'ts of Freezing Foods One of the major forms of food preservation is freezing, and an important part of frozen food storage is the container the food is packed in. There are several different types of packaging materials that work well in freezers. They include rigid containers, flexible bags, collapsible cover boxes and freezer wrap.
Rigid containers can hold most foods.
The containers are re-usable and are easy to stack. They are helpful for storing foods that contain liquids. With proper care, these plastic containers can be used for years. Wash lids in warm, never hot, water. Be careful as you remove the lid from the container because the lid may stretch and not fit securely.
