The main characteristics of glass packaging containers are: non-toxic, tasteless; Transparent, beautiful, good barrier, airtight, rich and common raw materials, low price, and can be used repeatedly. It has the advantages of heat resistance, pressure resistance and cleaning resistance. It can be sterilized at high temperature and stored at low temperature. Because of its many advantages, it has become the preferred packaging material for beer, fruit tea, jujube juice and many other beverages. Glass products are made of broken glass, soda ash, sodium nitrate, barium carbonate, quartz sand and more than ten kinds of raw materials. They are made by melting and shaping at 1600 ℃.
Glass bottles of different shapes can be produced according to different molds, mainly including various wine bottles, beverage bottles, pickle bottles, honey bottles, can head bottles, water bottles, carbonated beverage bottles, coffee bottles, tea cups, 0.5kg/2.5kg/4kg wine jars, etc,. The glass bottle is airtight and transparent, and can keep the product which is highly sensitive to humidity for a long time.
Due to the different glass production process, almost all glass products will produce a certain amount of broken glass in the process of production and processing. Flat glass in building materials industry is easy to recycle because of its large output and single product. The current recycling rate is also very high. However, the glass products and glassware products in the light industry have different shapes and low output, so the recycling process is relatively complex. Broken glass is rich in impurities introduced in the melting process of glass, so it may affect the performance of glass itself.
