Glass has been around for a long time in the development of mankind. For us, glass is one of the most incredible and useful materials that has been used in every area of human endeavor.


At the same time, we also know that glass is a man-made material. The main raw materials for glass are sand, soda ash, calcite, and feldspar, which make up more than 98% of the raw material for glass.


Other minor materials include clarifying agents, coloring agents, decolorizing agents, and so on. In addition, thanks to the power of glass, we also use broken glass as one of our main raw materials (generally in the range of 0% to 50%, sometimes even 100%,) in order to recycle it and reduce energy consumption.


This is why we say that glass is an environmentally friendly material.


Glass packaging materials and containers have several advantages.


1、Glass materials have good barrier properties, which can well prevent oxygen and other gases from attacking the contents and can prevent the volatile components of the contents from evaporating into the atmosphere.


2、Glass bottles can be used repeatedly and many times, which can reduce packaging costs.


3、Glass can be more easily changed in color and transparency.


4、Glass bottles are safe and hygienic, have good corrosion resistance and acid corrosion resistance, suitable for packaging acidic substances (such as fruit and vegetable juices and drinks).


5、In addition, glass bottles are suitable for the automatic filling of production lines.


The main raw materials for glass bottles are natural ores, quartzite, caustic soda, limestone, etc.


Glass bottles have a high degree of transparency and resistance to corrosion, and contact with most chemicals will not change the nature of the material.


Its manufacturing process is simple, its shape is free and versatile, it is hard, heat-resistant, clean, easy to clean, and has the characteristics of being reusable. Glass bottles are widely used as packaging materials for food, oil, beverages, spices, cosmetics, and liquid chemical products.


But glass bottles also have their disadvantages, such as heavy weight, high transportation, and storage costs, and not being resistant to impact.


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


They have good chemical stability; easy to seal, airtight, transparent, can be observed from the outside of the contents; glass bottle storage performance; glass bottle surface clean, easy to sterilize; glass bottle shape beautiful, glass bottle decoration colorful; glass bottle has a certain mechanical strength, a glass bottle can withstand the pressure inside the bottle and the external force of the transport process; glass bottle raw materials are widely distributed, glass bottle has Low price and other advantages.


The disadvantage of glass bottles is that they are brittle and fragile.


However, with the use of thin-walled lightweight and physical and chemical toughening of new technology, these shortcomings have been significantly improved, and thus the glass bottle can be in fierce competition with plastic, iron hears, and iron cans, production increased year by year.
