After preventing the beverage cans made of thin aluminum or thin metal skins from being filled with beverages, they were damaged during transportation and stacking. A British food company used ammonia to increase the strength of beverage cans. The effect was significant. Before beverage filling, nitrogen is dissolved in the beverage. After the beverage can is sealed, nitrogen is released from the beverage, forming a pressure on the tank wall, making the beverage can be an inflatable can, thereby increasing the can of the beverage can. strength. The canned beverage will not be damaged by stacking, operation and placing, and the quality of the beverage will not be affected by ammonia. This method of increasing the strength of beverage cans in nitrogen can be used in flexible packaging of beverages made from poly-methylene plastics. Reprinted from: Guangdong Packaging
