What are the production processes of food storage jar
The glass food storage jar has good transmission and light transmission performance, high chemical stability, and can obtain strong mechanical strength and thermal insulation effect according to different processing methods, and can even make the glass self-discoloring, and isolate the excessively strong Light, so it is often used in all walks of life to meet different needs. Next, please look at the production process of glass food Storage jar to improve your understanding.
Why choose glass food Storage jar
The main features of glass food storage jar are: harmless, tasteless; transparent, beautiful, good barrier property, airtight, abundant and common raw materials, low price, and can be used for multiple turnovers. And it has the advantages of heat resistance, pressure resistance and cleaning resistance, and can be sterilized at high temperature and stored at low temperature. It is precisely because of its many advantages that it has become a packaging material for food, seasoning and other products.
Production process of glass food Storage jar
First of all, it is necessary to design and manufacture the mold. The glass raw material uses quartz sand as the main raw material, and other auxiliary materials are melted into a liquid state at high temperature, and then injected into the mold, cooled, cut, and tempered to form a glass food storage jar. Glass food Storage jars generally have rigid signs, and the signs are also made of mold shapes. The molding of glass bottles can be divided into three types: manual blowing, mechanical blowing and extrusion molding according to the production method. Glass bottles can be divided into the following categories according to their ingredients: one is sodium glass, the other is lead glass, and the third is borosilicate glass.
The main raw materials of glass food Storage jar are natural ore, quartz stone, caustic soda, limestone, etc. The glass food storage jar is highly transparent and corrosion-resistant, and will not change its material properties in contact with most chemicals. Its manufacturing process is simple, free and changeable in shape, high in hardness, heat-resistant, clean, easy to clean, and can be used repeatedly.
