The benefits of glass bottles for cosmetic packaging

The composition of glass is relatively stable, and it is not easy to produce chemical reaction with skin care products.Colloquial point, it is to use glass bottles to pack skin care products, not easy to deteriorate.Glass bottles have a sense of advanced, the merchants sell skin care products mainly marketing is two concepts, appearance level + effect, transparent glass bottles often give consumers a sense of advanced, and filling some transparent or colored skin care products are very good-looking.In general, glass cosmetics container coloring is also known as "sulfur carbon" coloring, but the carbon only plays a reducing role, does not participate in the coloring, the real role in the color of the determination is the sulfur.In the glass melt, the sulfur in the form of S2- sulfide and the iron in the glass raw material coexists in the form of Fe3+. The volume of The product of Fe3+ and S2- ions is used as a marker to measure the chromaticity concentration, which determines the color density of the glass.For glass cosmetic containers, its quality is not only determined by the internal quality of the product, but also from the external observation, so the coloring process is very critical.In order to control the color of glass cosmetic containers, we need to consider from multiple hair sides, because it is limited by a variety of conditions, from the quality of raw materials, the ratio of raw materials to melting each link will have a certain impact on the formation of color.
