A food storage container is used to hold food at room temperature, in the refrigerator, or in the freezer. There are several options available for storing food in any of these manners. Before selecting the type of container to use, several factors must be taken into consideration. Consider the type of storage (room temperature, refrigerated, or frozen), the food being stored, length of storage, and storage space. The container can be a plastic bag, plastic container, or glass container.
