We generally say that grinding is a process of making the original surface smooth objects become not smooth, so that the light shines on the surface to form a diffuse reflection. For example, ground glass makes it opaque, and ground leather clothes to make them less shiny than ordinary leather. Make the original smooth things not smooth. This special treatment effect is gradually emerging in all kinds of products nowadays. Grinding effect can make the product more textural and artistic, and improve the product's appearance and grade. In the packaging market, glass bottles using grinding technology has been widely used, and now frosted plastic bottles
are gradually beginning to appear in the market.
With the development of the plastic bottle market, grinding technology is gradually used in plastic bottles, such as acrylic cosmetic bottles and plastic camellia oil bottles have begun to use grinding technology. For frosted plastic bottles, the processing of external packaging is not like glass bottles, which can be sprayed, baked and other processes. Therefore, grinding technology for plastic bottles is very precious.
