First of all, to design and manufacture mold, glass raw materials to quartz sand as the main raw material, plus other accessories at high temperature to dissolve into liquid, and then injected into the mold, cooling, cutting, tempering, the formation of glass bottles. Glass bottles generally have rigid signs, and the signs are also made of mold shapes. The molding of glass bottles can be divided into three kinds according to the production method: artificial blowing, mechanical blowing and extrusion molding. Glass bottles can be divided into the following types according to their composition: one is sodium glass, the other is lead glass, and the other is borosilicate glass

The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone and so on. Glass bottles have a high degree of transparency and corrosion resistance, and contact with most chemicals will not change the material properties. Its manufacturing process is simple, free and changeable shape, high hardness, heat resistance, clean, easy to clean, and has the characteristics of repeated use. As a packaging material, glass bottles are mainly used in food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, etc., and have a wide range of uses. But glass bottles also have its disadvantages, such as large weight, high transportation and storage costs, and impact resistance.

The characteristics and types of glass bottles: glass bottles are the main packaging containers for food, medicine and chemical industries. They have good chemical stability; Easy to seal, good air tightness, transparent, can be observed from the outside to contain the situation; Good storage performance; Smooth surface, easy to disinfect and sterilize; Beautiful shape, colorful decoration; Has a certain mechanical strength, can withstand the pressure in the bottle and the external force in the transportation process; Wide distribution of raw materials, low price and other advantages. The disadvantage is that the quality is large (mass to capacity ratio is large), brittleness is large, fragile. However, with the new technology of thin wall and light weight and physical and chemical tempering, these shortcomings have been significantly improved, so that glass bottles can increase year by year under the fierce competition with plastics, iron cans and iron cans.

There are a wide variety of glass bottles, from small bottles with a capacity of 1ML to large bottles with a dozen liters, from round, square, to shaped and handle bottles, from colorless transparent amber, green, blue, black blackout bottles and opaque milky glass bottles, etc., too numerous to mention. In terms of manufacturing process, glass bottles are generally divided into two categories: molded bottles (using models to make bottles) and controlled bottles (using glass bottles). Molded bottles are divided into two categories: large-mouth bottles (bottle diameter above 30MM) and small-mouth bottles. The former is used to hold powder, block and paste items, and the latter is used to hold liquids. According to the form of bottle mouth is divided into cork bottle mouth, screw bottle mouth, cap bottle mouth, rolling bottle mouth frosted bottle mouth, etc. According to the use, it is divided into "one bottle" that is used once and discarded, and "recycling bottle" that is used many times. According to the contents of the classification, can be divided into wine bottles, beverage bottles, oil bottles, cans, acid bottles, medicine bottles, reagent bottles, infusion bottles, cosmetics bottles and so on.
