Whether you are looking to buy a tin can for your food business or simply looking for some information on the tin can size, it is important to know exactly how thick a tin can is before you buy it. There are three different types of cans. These include a three-piece welded can, a two-piece drawn and ironed can, and a seamless tin.
A three-piece welded can is made of a rectangular flat sheet of food-grade steel, which is sealed close to the top and bottom. This is the most common type of can. The sides are attached to each other with a welded seam. The seams are attached by heat and usually have a gradual transition from the rim to the base. The rim is usually a narrow ring, slightly larger than the outside diameter of the can. The inside diameter of the rim is located just adjacent to the recessed surface. This design is considered to be the best option for preventing dents in the can.
Alternatively, a two-piece drawn and ironed can is a lightweight, thin piece of tin, made of a deep-drawn cup-shaped piece, with a flat top and a round base. The bottom end of the can is attached with a double seam. This is considered a hermetic seal. A plug-style metal cap fits snugly to the interior of the tin.
The tin can size is generally expressed in ounces, with the first digit indicating the number of inches. The second and third digits are the sixteenths of an inch, which are used to determine the can size. The chart below illustrates the standardized can sizes by volume. Depending on the volume of the can, the ounce size may be slightly different.
The most commonly used tin can size is 0.28 mm thick. This is sufficient for a tin can that is relatively large. It is also used for custom tin can products, such as beer kegs. For smaller tin cans, a thickness of 0.23 mm is often used. Tinplate is usually coated with 1 to 10 um thick films.
Some cans have easy-open features, such as hinged covers, or slipcovers. Other cans have additional information on the label, such as a recipe. Some cans also have screw caps that can be used to pour liquids into the can. There are also cans that are sealed under aseptic conditions. These cans are usually filled with pressure-sterilized food.
If you are looking for information on the tin can size, you may be interested in the CMI Voluntary Can and End Dimension Reference Manual. This is a free resource for CMI members and other industry representatives. While the manual is not guaranteed to be accurate, it contains information on the various tin can sizes and their capacities. However, the manual does not provide a warranty of viability for the cans that are sold.
The tin can is one of the most common containers used in the food industry. They are ideal for acidic fruits and juices, as well as light colored acidic beverages. Aside from the obvious benefits of durability and corrosion resistance, tin cans have several other advantages.
