Legends about the origin of Chinese tinplate

Tinplate prequel

In 1801, the Frenchman Nicolas Apert invented the long-term food preservation method, which put the food into glass bottles and heat treatment, so that the food crystals could not be preserved.

In 1809, the British Peter Durand used Nicolas Apert’s method to create the first tinplate container, all of which were jars instead of glass bottles. Thus began the development history of food cans, but the tinplate containers used at that time were all welded cans made of solder. Until 1897, the American Max Ams invented the method of sealing with rubber sealant, and the crimp can (that is, the double crimp seal) was born.

Legends about the origin of Chinese tinplate

Tinplate is an iron sheet coated with a layer of tin on the surface. It is not easy to rust, and it is also called tin-plated iron. This kind of coated steel plate has been called “tinplate” in China for a long time. There are three legends about the origin of its name:

Legend 1: It was introduced from Macau (MACAO), and its homonym was taken, so it was named tinplate, also known as Yangtie.

Legend 2: According to another legend, it was imported from the Makou area of the Ngari Department of Tibet, hence the name.

Legend 3: In the past, China used this kind of tinplate to make the lamp holder of kerosene lamps, which was shaped like a tinplate, so it was called “tinplate”.

Tinplate Features

(1) Environmental protection: tinplate cans are easy to oxidize and decompose, and are conducive to waste sorting and treatment, and can be recycled and reused.

(2) Safety: good sealing performance and long shelf life.

(3) Consumption: Iron cans have good thermal conductivity and are easy to heat and cool, which meets the needs of consumers. It has sufficient strength and hardness, is not easy to deform, and is more convenient for handling and storage. The product has multi-level colors and exquisite appearance, satisfying the visual enjoyment of consumers.

(4) Economy: It is suitable for large-scale continuous production, and the investment cost is low, so that consumers can enjoy high-quality and low-cost products.

Basic structure of tinplate

Tin plate, commonly known as tin-plated thin steel plate, is abbreviated as SPTE (SPTE: Steel Plate Tin Electrolytic), which refers to cold-rolled low-carbon thin steel plate or steel strip coated with commercial pure tin on both sides. Tin mainly plays a role in preventing corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one material, which has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.
