In our normal life, glass is widely used as packaging because of its good chemical stability and internal content, no pollution, air tightness, high temperature resistance, safe and reliable use. Transparent or colorful and conducive to improve the grade of goods, easy recycling and conducive to the protection of the environment. You can find your glass bottles and jars used for cosmetic, food, liquor, beverage, medicine, home decoration and so on.
Glass used in life is generally sodium-calcium glass, which is made of quartz sand, soda soda, feldspar, limestone and other raw materials. It has a lot of advantages, such as non-toxic, tasteless, easy to seal, good air tightness, good stable in hot temperature and low temperature. It is good choice for the storage of goods. It is easy to clean and disinfect and it is the ideal packaging container.
Glass bottles and jars are recycled, it is Eco-friendly and environmental protective, waste glass bottles can be recycled and renewable, glass recycling is a closed loop system, creating no additional waste or by-products. so it has been recognized as the best packaging material. It can be repeatedly used, which will reduce packaging costs.
The average recycling rate of glass containers in Western European countries has reached 30.5%. By the end of the 20th century, The recovery rate of glass bottles is planned to reach 90% and the reuse rate to 60%. According to preliminary estimates, the “measures” could save 25 million liters of oil, 2 million tons of raw materials, 20 million marks (us $11.84 million) in waste disposal fees and 20 percent of the amount of waste glass in garbage.
Glass packaging has a certain mechanical strength, it can withstand the pressure in the bottle, at the same time can withstand the action of external forces in the process of transportation. Glass bottle and jar should have a certain mechanical strength because of the use of different conditions, can also be subjected to different stress. Generally can be divided into internal pressure strength, heat resistant to impact, mechanical impact strength, the strength of container is overturned, vertical load strength, etc.
Glass bottle is safe and healthy, it is the most stable of all packaging materials. Glass bottle has good barrier performance, which can prevent the volatile components of the contents to the atmosphere. There is no risk of harmful chemicals getting into the food or drinks that are packed in glass. No additional barriers or additives are needed. A glass bottle or jar is 100% pure glass. It has good corrosion resistance and acid corrosion resistance, so it is suitable for packaging acid (VA) substances (if vegetable juice, beverage, etc.
Glass bottle can be any size and shape, color can be transparent colorful as our need, and also many deep-processing is available, it can be heated at high temperature, which is the safest and the most excellent.
Glass bottles are easy to clean. It is not changed or damaged during washing, high temperature as plastics commonly do. Potential toxins are eliminated while upholding the structure and integrity of the glass bottle. There are many common methods for glass cleaning, which can be summarized as solvent cleaning, heating and radiation cleaning, ultrasonic cleaning, discharge cleaning, etc. among them, solvent cleaning and heating cleaning are the most common.
Glass bottle is always traditional packaging container, as glass is a very historical packaging material. Also it is suitable for the production of automatic filling production line, the development of glass bottle automatic filling technology and equipment is relatively mature. Though there are many kinds of packaging materials on the market, glass container still occupies an important position in beverage packaging, which is inseparable from its packaging characteristics that can not be replaced by other packaging materials.
There are many kinds of glass, which can meet the different needs of different packaging. By adjusting the material and process of glass manufacturing, manufacturers can make the properties of glass materials change greatly, so as to make it more stable and durable. For example, the commonly used toughened glass is far stronger than ordinary glass.
The development of glass is closely related to the needs of society, which will promote the development of glass. Glass has always been mainly used as containers, and glass containers account for a considerable part of the output of glass. With the progress of science and technology, the demand for the quantity and variety of glass continues to increase, and the quality, reliability and cost of glass are also paid more and more attention.
Glass packaging has been necessity in our daily life.
