Vintage Metal Lunch Boxes

A tin box (also known as a tin can) is usually made of iron sheet and is used to package items such as food, beverages, cosmetics, etc. The concave convex design is aimed at increasing the structural strength and stability of the iron box, as well as providing better sealing performance and ease of opening. The concave convex design can make the tin box more sturdy and withstand pressure. By increasing the structural strength of the concave and convex parts of the box, it is possible to prevent compression deformation during transportation and stacking, and protect the integrity of the...

The tin box may undergo deformation during the delivery process, but whether it will undergo deformation depends on multiple factors. Firstly, the thickness and quality of the tin box can affect its resistance to deformation. Thicker and stronger tin boxes are relatively more resistant to external pressure and impact, reducing the risk of deformation. Secondly, the quality and method of packaging and filling materials can also affect the degree of protection of tin boxes. Appropriate filling materials and packaging methods can reduce the vibration and collision of tin boxes during...

1. What is a tin box made of tinplate material? Tin plate, also known as tin plated iron, is a common term for electroplated tin thin steel plate, abbreviated as SPTE, which refers to cold-rolled low-carbon steel plate or strip coated with commercial pure tin on both sides. Tin mainly plays a role in preventing corrosion and rusting. It combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin in a single material, with the characteristics of corrosion resistance, non toxicity, high strength, and good ductility. Tin plate is...
