The characteristics of glass bottles and jars Glass bottles and jars were the first to be used in the manufacture of canned food, but because the quality could not meet the requirements of canning treatment, they were quickly replaced by tinned sheet steel cans. In recent years, due to the continuous improvement of the production technology of the glass industry, the quality of glass jars has been improved, and the variety has increased, and the application in the canning industry has developed rapidly. The rapid development of glass bottles and jars is because it has some advantages that other containers do not have:
1. The chemical properties of the glass are stable, it will not interact with food, and it can maintain the original taste of food without metallic odor.
2. The glass container is transparent and beautiful, and the color and shape of the contents can be seen directly, which is convenient for consumers to choose.
3. Can be recycled and reused.
4.In the past, glass bottles and jars were heavy and easy to break, so they were generally only used in jam cans. Recently, due to the production of lightweight thin-walled bottles, glass bottles and cans have been widely used in mushrooms and other cans.
