airless glass cosmetic bottles

airless glass cosmetic bottles Here is a small summary of the glass packaging materials Definition: Glass is formed by melting together silica and other chemical substances (the main raw materials are: soda ash, limestone, quartz). A non-metallic silicate material that forms a continuous network structure during melting and whose viscosity increases and hardens during cooling resulting in crystallization. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with an irregular structure. There is no special material classification for glass bottles, but it is mostly classified by purpose. Second, the advantages of cosmetic packaging glass bottles 1, the glass material is lead-free and harmless, the barrier performance is good, can well prevent the oxidation of various gases on the object in the bottle, and can effectively prevent the volatile components of the internal char…
