Glass packaging products have the advantages of non-toxic, tasteless, transparent and beautiful, good barrier, pressure resistance, high temperature resistance, etc. Compared to plastic, paper, metal and other packaging materials, glass packaging materials are more stable chemical properties, is the safest at this stage of a packaging material.
1、Common types of glass packaging
Glass packaging materials in cosmetics are mainly used in cream bottles, serums, toners, essential oil bottles and other areas. Glass packaging materials mainly by the main materials, auxiliary materials, special materials with three categories. The main materials mainly include silica sand (or quartz powder), soda ash (Na2CO3), limestone (CaCO3); auxiliary materials mainly include clarifying agents (generally sulfate), co-solvents (generally nitrate, sulfate); special materials (generally oxidizing agents, physical decolorizing agents). 
Glass packaging products have the advantages of non-toxic, tasteless, transparent and beautiful, good barrier, pressure resistance, high temperature resistance, etc. Compared to plastic, paper, metal and other packaging materials, glass packaging materials are more stable chemical properties, is the safest at this stage of a packaging material.
2, glass packaging advantages
Glass packaging is one of the four major materials in the packaging industry, with a market share of 15%. Glass due to its own excellent characteristics and the continuous improvement of the manufacturing process, the current stage of glass packaging materials are still able to meet the food, pharmaceutical and most other industry applications. Glass packaging materials mainly have the following advantages.
a, glass materials have excellent protective properties, impermeable, impermeable to moisture, UV shielding, good chemical stability, non-toxic and odourless, can effectively preserve the contents.
b, glass transparency is good, easy to shape, can achieve the function of beautifying goods.
c, glass packaging materials are more plastic, can be made into a variety of styles of packaging materials, to a great extent to meet the diversity of commodities.
d, glass strengthening, lightweight technology and composite technology has been developed to strengthen the adaptability of the packaging, especially in the one-time packaging materials, glass materials have a strong advantage.
