The lid or "end" is usually tinplated steel while the body can be of metal (such as cans for beverages and soups), paperboard (whisky cans) or plastic. The seam formed is generally leak-proof, but this depends on the product being canned. The seam is made by mechanically overlapping the two layers to form a hook. Different parameters of the hook are measured [...]
Canning Methods Food Preservation during the Canning Process To prevent the food from being spoiled before and during containment, a number of methods are used: pasteurisation, boiling (and other applications of high temperature over a period of time), refrigeration, freezing, drying, vacuum treatment, antimicrobial agents that are natural to the recipe of the foods being preserved, a sufficient dose of ionizing radiation, submersion in a strong saline solution, acid, base, osmotically extreme (for example very sugary) or [...]
What is a Double Seam? A double seam is a canning process for sealing a tin can by mechanically interlocking the can body and a can end (or lid). Originally, the can end was soldered or welded onto the can body after the can was filled. However, this introduced a variety of issues, such as foreign contaminants (including lead and other harmful heavy metals). The double seam was later developed as a cheaper and safer alternative and quickly replaced the [...]
