Characteristics and types of glass bottles: glass bottles are the main packaging containers for the food, pharmaceutical and chemical industries. They have good chemical stability; easy to seal, good air tightness, and transparency, and the contents can be observed from the outside; good storage performance; smooth surface, easy to disinfect and sterilize; beautiful shape, colorful decoration; certain machinery The strength can withstand the pressure in the bottle and the external force during transportation; the raw materials are widely distributed and the price is low. The disadvantages are high quality (large mass to capacity ratio), high brittleness and fragility. However, with the new technology of thin-walled lightweight and physical-chemical toughening, these shortcomings have been significantly improved, so the production of glass bottles can increase year by year under the fierce competition with plastics, iron cans and iron cans.
There are many varieties of glass bottles, from small bottles with a capacity of 1ML to large bottles of more than ten liters, from round, square, to shaped and handle bottles, from colorless and transparent amber, green, blue, black shading bottles and opaque The opaque glass bottles are endless. In terms of manufacturing process, glass bottles are generally divided into two categories: molded bottles (using model bottles) and control bottles (using glass control bottles). Molded bottles are further divided into large-mouth bottles (with a mouth diameter of more than 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 the bottle mouth, it can be divided into cork bottle mouth, screw bottle mouth, crown cover bottle mouth, rolling bottle mouth frosted bottle mouth, etc. According to the use situation, it is divided into “one-time bottle” that is discarded and used once and “recycling bottle” that is used many times.
