In the field  of cosmetic packaging, some glass bottle packaging needs to be more textured, nothing more than spraying or frosting, or bronzing. At present, frosting has the lowest cost, and frosting will not cause harm to the product. It is through pickling to make the outer surface of the glass bottle even and rough, a bit like a matt feeling.The spraying cost is almost same or more than bottle itself, the bronzing cost will be much more.
