Quick Summary

A tin can is a container made of tinplate, which is essentially sheet steel with a thin coating of tin. This coating provides the steel with noncorrosive and nontoxic properties, making it ideal for packaging.123

The process of tinning iron sheet to create tinplate began in Europe centuries ago, initially for household items. However, with the invention of food canning in 1812, packaging became the primary use for tinplate. Modern tin cans are typically made from steel with a tin coating applied through electroplating. Approximately 90% of all tinplate is used in the packaging industry for processed foods and beverages. While aluminum cans are now common for drinks, tinplate cans remain prevalent for many food products due to their strength and protective qualities.4235
