Tinplate is an iron sheet coated with a layer of tin on the surface, which is not easy to rust and is officially known as tinned steel sheet. Tinplate was originally produced in Bohemia (now within the Czech Republic and Slovakia). The area has been rich in metals since ancient times, with advanced technology and the ability to use water power for machine manufacturing. It has been producing tinplate since the 14th century. For a long time, this has been the main producer of tinplate in the world. At that time, tinplate was mainly used to manufacture tableware and drinking utensils.

In the 17th century, Britain, France, and Sweden all hoped to establish their own tinplate industry, but due to the need for large amounts of capital, it was not carried out for a long time. Until 1811, Brian Tang Jin and John After Hall opened canned food made of tinplate, tinplate manufacturing began on a large scale.

The so-called "tinplate" is a title or common name used for products. The word "Ma Kou" comes from the transliteration of the foreign name "MaCao" in Macau, which was originally called "Tin Plate". As the first batch of foreign iron was imported from Macau in the mid Qing Dynasty, Macau transliterated it as "Ma Kou" at that time. Therefore, Chinese people generally refer to it as "Ma Kou Tie".
