Square Storage Containers

Square Food Containers: What You Need to Know

Foodservice operations that store food for future use but don't need a long-term solution, such as vacuum sealing, can use commercial square food containers to store prepared courses, partially prepared courses, and raw or cooked ingredients. These containers offer a lightweight, durable option suitable for pantry or refrigerated storage and may be rated for high or freezing temperatures.

Graduated labels usually are printed on the side of the containers, removing the need for a dedicated measuring device when packing. Sizes range from 2 to 22 quarts, with large containers including handles for easy transport. Depending on what they're made of, square food storage containers often resist stains, acids, and odors. The square shape means these containers can be organized more closely together than round containers, maximizing the amount of product that can be stored in one area.

Common Questions About Square Food Storage Containers

What materials are available?

Square plastic food containers are available in clear polycarbonate, nearly opaque polyethylene, and translucent polypropylene. Polycarbonate containers have the highest temperature ratings, usually above 200 degrees. However, polyethylene and polypropylene containers are BPA free, while polycarbonate containers are not.

Are heat-resistant containers microwave safe?

Heat-resistant plastic materials are dishmachine safe, but generally cannot withstand higher temperatures involved with microwaving and other cooking methods. Research manufacturer recommendations before attempting to use your containers for anything besides storage.

What containers can be used for sous vide cooking?

Provided temperature ratings are not exceeded, operators can use plastic food storage containers for sous vide, which uses a water bath to cook vacuum-sealed food slowly. Check container heat ratings against the desired water temperature for your application before sous vide cooking.

How do I ensure food safety?

Users can label their food by contents, date in, and expiration date to ensure proper use and prevent cross contamination. A first-in, first-out system ensures food is likelier to get used before its expiration, reducing food waste and increasing customer safety. Operations providing allergen-free options should consider purchasing containers with special markings or labels that set them apart. These containers may use purple lids, graduations, and "Allergen-free" labels.

What kind of lids are available?

Square plastic food containers with lids may include color coding to avoid cross contamination; lid colors may also correspond to container size. Operators can also purchase clear lids and lids that create a strong seal to prevent spills, which is especially useful for storing soup and other liquids.

What does NSF listed mean for a commercial square food container?

NSF International is a public health organization that guides sanitation standards. An NSF listing for a square storage container means the product has been rigorously tested to ensure it meets commercial standards for cleanability and reuse.
