Metal food containers are widely used in the canning industry because of their ability to maintain themselves unaltered over time and to maintain their contents.
This practice has its roots in the long and historical maritime expeditions that characterized the nineteenth century, beginning with Sir John Ross, historical explorer of the Arctic, who in 1818 restocked his ship with canned food in tin cans.
The need to provide on-board staff with a healthy, varied and vitamin-rich diet, thanks to the discovery of researchers on food decay (Pasteur), introduced the use of canned foods in tins, which ensured a perfect diet for the sustenance of the ship’s crew.
In Italy, Francesco Cirio, who in 1856 started the packaging of food in metal cans, exporting its historical preserves all over the world.
Since those days, the production of metal cans has come a long way both in terms of manufacture and in terms of market penetration.
