Container bags can be recycled, so it is an energy-saving and environmentally friendly product. We know that the color of container bags is relatively single, mostly red, but in the process of recycling, we may need to use some processing methods to whiten them, so let's take a look at what processing can enhance the whiteness of container bags.
1. Gray recycled materials are dyed white, and more or less container bags are still white with gray. If black is dyed white, it can only become light gray. It is necessary to add more ultramarine, which can make the gray component appear bright gray and not so embarrassing.
2. Improved opacity: Adding titanium dioxide makes plastic opaque. Titanium dioxide can strongly scatter or refract light. If enough titanium dioxide is added during the process of container bag flat wire, all the light shining on its surface will be reflected, making the flat wire appear opaque and obviously red.
3. Since plastic itself has color and transparency, its whiteness is significantly different from that of woven bags made of pure materials. Therefore, adding titanium dioxide can increase the whiteness.
