Glass containers for canned food

Glass containers for canned foodGlass jars, bottles, bottles are widely distributed in the canning industry for packing canned fruits and vegetables. In some years, the production of canned fruits and vegetables in glass containers reached 70-80% of the total production of canned goods.

 

Glass containers are sealed with metal lids, and there are different ways of fixing the metal lid on the neck, or, as it is commonly used, different ways of sealing, depending on the design of the neck corolla.
