Things to Consider When Choosing Glass Food Jars

Size and Shape of Glass Food Jars: Glass food jars come in a variety of sizes and shapes, so it is crucial to choose the right jar for your specific needs. Consider the amount of food you need to store and the space available in your refrigerator or pantry.

Color of Glass Food Jars: If you are packaging a light-sensitive product (such as oil), you can choose colored glass to filter out UV rays.

Lid of Glass Food Jars: Make sure the lid fits tightly to create a seal.

 

Production Process of Glass Food Jars
To make glass packaging, silica sand, soda ash, limestone, and crushed materials are poured into a furnace heated to 1500°C to form molten glass. After the melting stage, the glass becomes inhomogeneous and contains many bubbles. To remove these bubbles, the glass needs to be refined, that is, the glass is heated to a higher temperature, then to 1250 ° C, to obtain the ideal glass viscosity. Then, the liquid glass is fed into channels that deliver the glass to the molding machine at the ideal temperature and viscosity to form the final packaging. The glass is poured into the blank mold in the form of a drop (called a parison) and then poured into the finishing mold. This drop of glass can undergo two processes: pressing or blowing.

 

The pressure blowing technology consists of pressing the glass drop into a blank with a piston, and then injecting an air flow into the preform obtained in advance to shape the product. This technology is the preferred technology for making glass jars. The second technology is blow molding, in which the drop is compressed and then pierced. After the first blow molding, the preform is produced and the bottleneck is formed. Another air flow is injected into the final mold to shape the package. This method is the preferred method for making bottles.

 

Next comes the annealing stage. The molded product is heated in a firing arc and gradually cooled to about 570°C to enhance the strength of the glass. Finally, the glass jars are grouped and packaged to ensure their safety.
