Food Cans Buying Guide

Canned goods extend the shelf life of many food items without sacrificing nutritional value for a lower cost than fresh or frozen options. Unlike fresh produce that loses nutrients over time and frozen products that may lose nutrients through oxidation, canned foods are sealed at peak ripeness and retain their nutritional properties for extended periods. With advantages such as preserving food quality over time, extending product shelf life, and ensuring packaging safety, food cans play a crucial role in foodservice.

Can Sizes Chart

Our can size chart provides a helpful breakdown of the different can size numbers and their equivalent weight or cup size. The measurements in ounces in this chart refer to what is in the can, not product yields from using the can. Some sizes can also vary by a few ounces depending on the specific product you purchase, so always read the label closely.

Reading Food Can Dimensions

Most recipes and can racks will specify a can size rather than a volume. Knowing the dimensions and capacities of the most common cans on the market is imperative when planning meals and evaluating storage space in the foodservice industry. Restaurants, cafeterias, daycare centers, and more rely on canned goods as a quick, economical way to serve patrons.

In the United States, packers measure metal cans before seaming. These dimensions are nominal and use a conventionalized method in which three-digit numbers express each dimension. Within each three-digit grouping, the first digit indicates the number of whole inches in a dimension. The second and third digits indicate the fractional inches as sixteenths of an inch.

The first three-digit number indicates the diameter measured across the outside of the chime on the seamed end. The second three-digit number indicates the overall height of the can.

  • 303 x 406 means 3 3/16 x 4 6/16 inches
  • 307 x 512 means 3 7/16 x 5 12/16 inches
  • 603 x 700 means 6 3/16 x 7 inches

Types of Food Cans

From a manufacturing standpoint, food cans are assembled from two or three pieces of metal. Two-piece cans have fewer seams, which lessens the chance of compromising the integrity of the can. However, three-piece cans are easier to open and produce than two-piece cans.

Two-Piece Metal Food Cans

Two-piece metal food cans feature a body integrated with a bottom lid and a lid with a lip. These cans are made using a drawing process in which a coil of coated rolled metal is fed into a press and formed into a cup-shaped object, complete with a flat, round bottom and cylindrical side walls. There are two types of two-piece cans based on the manufacturing process:

  • Draw and Redraw Cans (DRD): The cups go through a second drawing phase, or the redraw, to achieve the final shape.
  • Draw and Wall Ironing Cans (DWI): The cups go through a wall ironing phase that results in the cup walls being stretched and ironed to a predetermined height.

Whether the can is redrawn or ironed, the final step is to trim the cup into a finished container before filling and sealing the top lid via double seaming.

Three-Piece Metal Food Cans

Three-piece metal food cans feature a bottom lid, cylindrical body, and top lid. These cans are made with a rectangular, flat sheet of food-grade steel shaped into a cylinder and closed with a vertical side seam. The bottom end is then attached via "double seaming" to create a hermetic seal. Once filled, the can is closed at the top with a similar seal to the bottom. Depending on the manufacturer, three-piece cans are soldered or welded for assembly.

Food Can Materials

The most common materials used for food cans are steel, tin, aluminum, and paper, each offering unique benefits for commercial food storage. Each material has characteristics that make it suitable for different food products.

Steel

Steel is commonly used for food cans due to its durability and strength, but manufacturers will coat it in tin or aluminum to prevent corrosion. They provide excellent protection for food products, making them ideal for long-term storage and transportation. Additionally, steel cans are recyclable, making them a sustainable packaging option for businesses looking to reduce environmental impact.

Tin

Tin is often used as a coating for steel cans to prevent corrosion and enhance the shelf life of canned foods. Cans with tin coatings are suitable for acidic foods, as tin provides a barrier against interactions that could affect the taste or quality of the product. Due to these properties, tin cans are popular for canning fruits, vegetables, and acidic sauces.

Aluminum

Aluminum cans are light weight and resistant to corrosion, making them a popular choice for packaging beverages and food products. They are easily recyclable, with high recycling rates contributing to sustainable packaging practices. The flexibility of aluminum allows for creative packaging designs and shapes, making it an adaptable material for food cans.

Paper

Though less popular than metal, paperboard cans are an eco-friendly alternative that offers a sustainable packaging solution for environmentally conscious businesses. They are light weight and easily customizable, making them ideal for packaging dry goods, snacks, and confectionery products. The recyclability of paperboard cans further enhances their appeal as a sustainable packaging option in the food industry.
