Question

Why are tin cans used for storing food?

Answer 1

Hint: A tin can is a thin metal container used for the distribution or storage of products. Many cans must be opened by cutting the "end" open; others have lids that can be removed. They may hold a wide range of items, including food, drinks, oil, chemicals, and so forth. Tinplate (tin-coated steel) or tin-free steel are used to make steel cans. Even aluminium cans are referred to as "tin cans" in some languages.

Complete answer:
Tin cans are created by electroplating tin on iron and keeping food in them. Tin is a more reactive metal than iron. As a result, food does not come into touch with iron and is therefore protected against spoilage.

Steel cans are great drinking containers for a variety of reasons. Steel cans are more durable than cartons or plastic and less brittle than glass, preserving the contents during transportation and minimising leakage or spillage while also eliminating the need for supplementary packing. Metal cans without resealable closures are among the most tamper-evident of all package materials since they offer 100 percent barrier protection against light, water, and air.

Steel cans maintain and protect the product from light, oxidation, extremes of temperature, and contamination from the production to the ultimate customer, ensuring flavour, appearance, and quality. Steel-can food and drink have the same vitamin content as freshly cooked food without the need for preservatives. Steel cans also increase the shelf life of the product, providing for longer sell-by and use-by dates as well as less waste.
Steel cans do not require refrigeration in the supply chain as an ambient packaging medium, simplifying transportation and storage while saving energy and money.

Note: No cans in widespread use today are made entirely or mostly of tin; rather, the phrase refers to the virtually exclusive usage of tinplate steel in cans until the second half of the twentieth century, which combined the physical strength and inexpensive cost of steel with the corrosion resistance of tin. Some canneries still utilise tin-free steel, depending on the contents and available coatings.
