Therefore, scientific containers and methods should be used to preserve tea, which has been constantly changed by people since ancient times.
The reasons for the preservation of tea in iron cans
The main reasons for storing tea in iron cans: in ancient China, there was a very meticulous attention to the preservation and preservation of tea. Generally, pottery pots (ceramic containers) were used to hold tea. Because the pottery pots were fragile, they were gradually replaced by iron cans.
At present, there are three ways to preserve tea: iron pot preservation, porcelain jar preservation and BAG preservation. These three methods need good temperature, dry and non humid, convenient storage and dark environment to ensure the long-term quality and taste of tea. After long-term use, it is found that these three kinds of containers, iron can packaging and ceramic preservation of tea are more suitable. However, considering the factors such as price and production technology, iron cans are more suitable as gifts to express the feelings between relatives and friends because of their exquisite printing, convenient carrying and novel style.
The tea tin can combines the characteristics of tinplate processing, the design of tea patterns and the shape characteristics of tea to carry out structural innovation, which meets the advantages of convenient use and, meets the requirements of the coordination between the model, the contents of tea and the consumer psychology, and gives full play to the function of the packaging tin. Therefore, it is a trend to preserve tea with an iron can.
