Advantages and types of glass bottles

Glass bottles are the main packaging containers in the food, pharmaceutical, and chemical industries.

They have good chemical stability; Easy to seal, good airtightness, transparent, and the condition of the contents can be observed from the outside; Good storage performance; Smooth and clean surface for easy disinfection and sterilization; Beautiful appearance, rich and colorful decoration; Having a certain mechanical strength, able to withstand the pressure inside the bottle and external forces during transportation; The advantages of wide distribution of raw materials and low prices. Its drawbacks are high quality (mass to capacity ratio), high brittleness, and fragility. However, with the adoption of new technologies such as thin-walled lightweight and physical chemical tempering, these shortcomings have been significantly improved. As a result, glass bottles can increase in production year by year in fierce competition with plastics, tin 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 capacity of over ten liters, from circular, square, to shaped and handled bottles, from colorless and transparent amber, green, blue, black opaque bottles, and opaque opaque glass bottles, to name a few. In terms of manufacturing technology, glass bottles are generally divided into two categories: molded bottles (using model bottles) and tube bottles (using glass tube bottles). Molded bottles are divided into two categories: large mouth bottles (with a diameter of over 30MM) and small mouth bottles.

The former is used to hold powder, block, and paste shaped items, while the latter is used to hold liquids. According to the form of bottle mouth, it can be divided into cork cork bottle mouth, threaded bottle mouth, crown bottle mouth, roller pressed bottle mouth frosted bottle mouth, etc. According to usage, it can be divided into "disposable bottles" that are discarded once and "recycled bottles" that are reused multiple times.
