The hottest new type of canned container paper can
2022-10-16- Detail
A new type of canned container paper cans recently, Japanese letterpress printing produces harmful volatiles. The company has invented a new canned container that can maintain a high degree of sealing and sterilization, and can avoid violent vibration and affect the accuracy of the experimental machine. It can be stored at room temperature for a long time. Its food preservation ability is not low, and the accuracy of the test is guaranteed to be higher than that of metal cans. Practice has proved that the quality of food in cans will not deteriorate for at least one year at room temperature. At present, this kind of paper can is used in the packaging of beer, fruit juice and other beverages, and has been highly praised. The main characteristics of this kind of paper can are:
1. It is lighter than iron cans and glass bottles
2. It is convenient for recycling, can be burned and pollution-free
3. it can be filled with high hydraulic pressure and temperature. Due to the use of aluminum foil packaging and edge protection, the penetration of oxygen is reduced, so the circulation and storage period at room temperature can reach more than 1 year
4. due to the shrinkage of the gap at the lid during filling, there is no deterioration of vitamin C in fruit juice drinks
5. The can body material is made of polyethylene, paper, aluminum, polyester (PET), etc., which can ensure the strength of the can body. Because it can flow directly in the original shape of the can, it can be used for automatic sales machines like traditional round cans
the design of this kind of paper can is to press ribs on the side of the barrel type tank. For the liquid that can be poured into the tank under high temperature conditions, when the temperature of the high-temperature liquid sealed in the tank drops and the pressure in the tank drops sharply, the side between the ribs is concave, so as to enhance the strength of the tank and avoid the phenomenon of shrinking. This is a key problem in the process of developing cans in the past
