Japan launches new paper can

Recently, Japan Toppan Printing Co., Ltd. has invented a new type of paper can that maintains a high degree of sealing and bactericidal properties and can be stored at room temperature for a long period of time. Its food storage capacity is not inferior to that of metal cans. Practice has proved that at room temperature, the quality of the food in the tank will not deteriorate in at least one year. At present, this paper can is used for the packaging of other beverages such as beer, fruit juice, etc., and has received favorable comments. The main characteristics of the paper cans are: they are lighter than cans and glass bottles; they can be filled at high temperatures. Due to the edge protection of aluminum foil packaging, the oxygen permeability is reduced, so the shelf life of the paper can reach more than one year at room temperature; It is made of polyethylene, paper, aluminum, polyester (PET), etc. It can ensure the strength of the can body and it can directly flow in the original shape of the can. Therefore, like the traditional round cans, it can be used by automatic vending machines; Can be burned without pollution. The design of the paper tank is concave on the side of the barrel tank, so that the strength of the tank is enhanced, and no helium phenomenon occurs. This is a key issue in the development of the tank in the past.
