Glass is also a very historical packaging material. In the case of many packaging materials flooding into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from the packaging characteristics that other packaging materials can not replace.
Colored glass jars have a series of advantages, such as cleanliness, beauty, transparency, high chemical stability, air-tight, easy to seal, keeping the properties of filling items unchanged, being able to be used many times, rich in raw materials, low prices, and so on. They have become widely used packaging materials in food, medicine, chemistry, and other industries. Glass jars have been under intense competition from white iron, plastic bottles, and so on, which forces them to constantly improve their production process in order to obtain a large number of low-cost and high-quality products. At present, glass jars have reached the level of complete automation in various production processes, such as raw material ingredient, melting, forming, annealing, product inspection, and packaging.

Glass jars have been subject to intense competition from tin bottles, plastic bottles, and so on, which forces it to continuously improve its production process in order to obtain a large number of cheap and high-quality products. Now the glass jars have reached the level of complete automation in the raw material batching, melting, forming, annealing, product inspection, packaging, and other production processes.
The production process of the glass jars mainly includes raw material pre-processing. The massive raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed to dry the wet raw materials. The iron-containing raw materials are doing the iron-removing to ensure the quality of glass. It is prepared by melting. The glass mixture is heated at 1550 ~ 1600 ℃ in the tank furnace or tank furnace to form a uniform and bubble-free liquid glass which meets the forming requirements. Put the liquid glass into the mold to make the required shape of glass products, such as heat treatment of the flat plate, various utensils, and so on. Through annealing, quenching, and other processes, it can eliminate or produce the internal stress, phase separation, or crystallization of the glass, and change the structural state of the glass.
Colored glass jars are often used in food packaging, gift packaging, pharmaceutical packaging, chemical utensils. You can also order custom glass jars for your special usage.
