1, gray recycled material dyed white, more or less bagged or white through the gray. If it is black and white, it can only become light gray. It is necessary to add more points of ultramarine to make the gray components appear innocent gray, not so ugly.
2, because the plastic itself has color and transparency, compared with the woven bag made of pure raw materials, its whiteness is significantly different, therefore, the addition of titanium dioxide can increase the whiteness.
3, improve the opacity: add titanium dioxide to make the plastic opaque. Titanium dioxide can strongly scatter or refract light, if enough titanium dioxide is added to the process of the flat wire, all the light irradiating its surface will be reflected, so that the flat wire shows opaque and obvious white.
The packaging information mainly refers to the glass bottle packaging used to package beer, drinks, etc., which can be used repeatedly. Recycled packaging data mainly refers to plastic packaging data, which can be made into recycled packaging containers after physical treatment. After chemical treatment, it can be made into recycled packaging products. However, the fly in the ointment of these two methods is that ton bagging only reduces the pollution to the environment, and when disposing, it also faces the problem of polluting the environment.
