The Use Characteristics And Types Of Glass Bottles What Are The Advantages Of Glass Bottle Packaging Materials

Glass has a long history and stable properties. It is an excellent material that has stood the test of time. It can not only be used for decoration, but also play an important role in various optical instruments, and can even be used to help buildings save energy and reduce noise. By using different processing methods, we are able to give glass different properties. Glass bottles have excellent performance and are suitable as packaging materials for various beverages. They are stable and durable and do not react with liquids.

1. The use 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, and the condition of the contents can be observed from the outside; good storage performance; smooth surface, easy to disinfect and sterilize; beautiful in appearance and colorful decoration; there are certain mechanical It has the advantages of high strength and 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 disadvantage is that it has large mass (large mass-to-capacity ratio), high brittleness and brittleness. However, with the new technology of thin-walled lightweight and physical and 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 a wide variety of glass bottles, from small bottles with a capacity of 1ML to large bottles of more than ten liters, from round, square, to special-shaped and handle bottles, from colorless and transparent amber, green, blue, black shade bottles and opaque bottles of opalescent glass bottles, and the list goes on. As far as the manufacturing process is concerned, 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 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 liquid. According to the form of the bottle mouth, it is divided into cork bottle mouth, screw bottle mouth, crown cap bottle mouth, rolling bottle mouth and frosted bottle mouth, etc. According to the usage, it is divided into "single-use bottles" which are discarded after one use and "recycling bottles" which are used for multiple turnovers. According to the classification of the contents, it can be divided into wine bottles, beverage bottles, oil bottles, canned bottles, acid bottles, medicine bottles, reagent bottles, infusion bottles, cosmetic bottles and so on.

2. What are the advantages of glass bottle packaging materials

        1. The glass material has good barrier properties, which can well prevent the invasion of oxygen and other gases to the contents, and at the same time can prevent the volatile components of the contents from volatilizing into the atmosphere;

        2. The glass bottle can be used repeatedly, which can reduce the packaging cost;

        3. The glass can easily change the color and transparency;

        4. Glass bottles are safe and hygienic, have good corrosion resistance and acid corrosion resistance, and are suitable for the packaging of acidic substances (such as vegetable juice drinks, etc.);

        5. In addition, because glass bottles are suitable for the production of automatic filling production lines, the development of automatic glass bottle filling technology and equipment in China is also relatively mature, and the use of glass bottles to package fruit and vegetable juice beverages has certain production advantages in China.
