In 1810, the British tried to preserve it better
It took more than 100 years for humans to make cans really easy to pull.

In 1959, the Americans invented the can, and they processed the material of the can lid itself to form a rivet, fitted with a pull ring and riveted tight, matched with a suitable score, and became a complete easy to pull cover.
It has to be said that this design is really good, which makes metal containers have been qualitative development, in the 1970s and 1980s, the can production line gradually transferred from the United States to Japan, South Korea and other places.

In the early 1980s, China’s Qingdao Brewery imported beautifully printed all-aluminum two-piece cans from Japan in order to meet the packaging needs of its products for export, which opened the prelude to the large-scale use of cans in China.

The products of the metal packaging industry are all kinds of metal cans, which can be divided into three cans and two cans.
The three-piece can is a metal package composed of three parts: the body of the can, the top cover and the bottom cover, with tinplate as the main material.
The two-piece can refers to the metal packaging composed of two parts, the body and the top cover, with aluminum as the main material.
The downstream industries facing the two are not the same, and the three-piece cans should be mainly used in the packaging of functional drinks, milk powder, tea drinks and other products; The two-piece cans are mainly used for carbonated drinks such as cola and beer and other inflatable drinks.
