Secondary oxidation: This is achieved by oxidizing the original oxide layer a second time, resulting in a pattern with a shiny surface and a matte surface, or a pattern with a matte surface that appears shiny. It is mainly used for the production of logos.
Injection coloring: Color powder is added to the raw material during product injection. This process is relatively inexpensive. It is also possible to add pearl powder or talcum powder to make PET transparent colors opaque (additional color powder can be added for color adjustment). The production of water ripples is related to the amount of pearl powder added.
