2023年4月4日 · A tin can, also known simply as a tin or a can, is an airtight metal container used for the distribution or storage of goods. Most “tin cans” are made of tin-plated steel rather than pure tin. In order to open a can, the metal must be cut or torn.

2003年12月1日 · Disollution of metallic tin from the inside of a can body into the food content will result in it being present in the divalent form. The precise chemical nature of the divalent tin in a canned food product is important, as it is likely to have a major influence on its ability to cause an acute toxicological response.

2022年6月24日 · The pressure inside the can shouldn't change much, as long as it's airtight. The outside force can only interact with the tin can. If the inside is pressurized though, we'd have to take these forces into account as well.

Food cans are usually tin coated steel. They may or may not have an organic coating, and many fruit cans leave exposed tin to reduce browning of the fruit with age. The surface phenomena that you see that looks like galvanizing is the organic acids in the fruit attacking the tin, which forms tin oxide and has a grey modeled appearance.

So in theory there is nothing to really worry about. The common sense answer is, if epoxy dissolved into the cans contents they wouldn't use it would they.

A tin can, also called a tin (especially in British English) or a can, is an air-tight container that is made of metal and used for the distribution or storage of goods. Most "tin cans" are not made solely of tin but of tin-plated steel. Opening a can requires cutting or tearing of the metal.

2022年12月12日 · The inside of the "tin" can is probably also coated with plastic. It's definitely not aluminum, but I can't explain how I know this, I might be wrong, but I've never heard of aluminum plating on food cans, and can't imagine it being cheap. And I've seen these crystal patterns from galvinisation (with zinc) all over the place.
