The tin on the inner wall of the tin box will react with the oxygen remaining in the container during filling, greatly reducing the chance of food ingredients being oxidized The reducing effect of tin has a good preservation effect on the flavor and color of light colored fruits and juices. Therefore, juice cans packaged in unpainted iron cans have better nutritional preservation than juice cans packaged in other materials, with slight brown changes and better preservation of flavor quality. As a result, the storage period is extended

At present, metal can packaging is recognized worldwide as a "safer and more environmentally friendly product". It is because the tinplate material used for metal can packaging has good impermeability and opacity, which can effectively prevent the contents from being oxidized by light and prevent pollutants from entering. Therefore, it has the characteristics of safety, hygiene, and health. Additionally, a more important point is that tin cans are more environmentally friendly containers because they can also be recycled and reused, in line with the national call for environmental protection. Moreover, if an empty can is placed in a natural environment, after 7 years of wind and rain, it will naturally oxidize, crush, or blend into the soil.

Tinplate is a common name for electroplated tin thin steel sheet, abbreviated as SPTE in English. It refers to cold-rolled low-carbon thin steel sheet or strip coated with commercial pure tin on both sides, also known as tinplate. Tin mainly serves to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin in one material, possessing the properties of corrosion resistance, non toxicity, high strength, and good ductility. Tinplate was called Tin Plate in the early days, because the first batch of Chinese tinplate was imported from Macao in the middle of the Qing Dynasty. Macao was transliterated into "tinplate" at that time, so Chinese people generally call it "tinplate"
