The difference between two cans and three cans of pop top cans

Easy open end beverage cans can be divided into two pieces cans and three pieces cans. The two pieces cans are mainly made of aluminium alloy sheets, which are mostly used for packing carbonated drinks. The three pieces cans are mainly made of tin plated steel sheet (tinplate), which are mostly used for beverage packaging without carbonated beverages.

The two pieces cans were made in the middle of the twentieth Century. The whole package can be made up of two pieces, that is, the can and the jar. It is called two cans. The tank body of the two plate is made of a sheet metal and is stretched by a punch to form a die so that it can be stretched and deformed so that the bottom of the tank can be connected into one body. There are many classification of two pieces cans. According to the body height, divided into shallow and deep drawing tank tank. According to the manufacturing materials, aluminium cans and cans. According to manufacturing technology, sub thin, stretch cans and deep drawing cans.

The application history of three pieces casn has been nearly 200 years. Although it has been improved many times, its basic composition is still made of three pieces of metal sheet (tinplate), which is named "pot body", "tank bottom" and "can cover". Therefore, it is named "three pieces of tin". The shape, size and manufacturing methods of the bottom and lid of an ordinary three piece can be exactly the same. There are two main types of sealing cans: soldering and welding of longitudinal seam. The rigidity of the three piece tank is good, and the pot with various shapes can be produced, the material utilization rate is high, the size is easy to change, the production technology is mature, and the product variety is various.
