Glass is made of silica and other chemical substances melted together (the main production of raw materials: soda ash, limestone, quartz). In the melting of the formation of a continuous network structure, the viscosity of the process gradually increased and hardened to cause the crystallization of silicate non-metallic materials.
Glass bottles is a traditional beverage packaging containers, glass is also a very historical packaging materials. In the case of many kinds of packaging materials into the market, the glass containers in the beverage packaging still occupies an important position, and it has other packaging materials can not replace the packaging characteristics inseparable.
In our daily life, you can see the glass bottle everywhere. Whether it is drinks, drugs, or cosmetics, etc., glass bottles are their good partners. These glass bottles, because of its transparent beauty, good chemical stability, the contents of non-polluting, high temperature heating, the old bottle can be recycled and other advantages, has been considered the best packaging materials.
In order to produce glass bottles, modern factories use two methods, through blowing and blowing processes or pressing and blowing techniques. Both processes involve cutting the molten glass stream with a shear blade to form a glass cylinder called a gob. Blank moulds are filled with gob, which falls delicately into the moulds through chutes and troughs. With the blow molding and blow molding process, the glass is mainly blown into the blank from below to produce a pre-vessel or pre-vial. The pre-container is then flipped into the final mold. Finally, the glass is made into its designed shape. In the pressing and blowing method, the preform is formed with a plunger made of metal. It will push the glass into the blank.
The glass bottles can now be packed and transported in bulk pallets, packed or packed in hand-stitched bags. Each package has a specific label and storage. Glass bottles can be recycled, and many governments have imposed high prices on broken glass to ensure equal returns. Glass bottles can be reused and practiced in many developing countries.
