Glass jars are a complex for many people as a child. Previously, canned fruit cans and canned meat products were foods that many people loved. It does indeed preserve food well. Glass jars and sealed lids can provide a great deal of food protection.
However, the form of the tinplate was very troublesome, and it was also aroused by some consumers. In recent years, there have been some screw-capped glass jars. Such glass jars are more convenient to open and are also more popular with consumers.
For glass jars, I think there are two directions for improvement in the future. One is the lightweighting of glass jars. It is too heavy now. The other is the sealing performance of the glass jar after the closure of the lid.
