A combination of naturally fine, calcium carbonate that is very white and is treated on the surface to increase compatibility. It is easier to mix and disperse, on linear polyethylene, with a flow index of 20 to achieve better dispersion in the resin to be stabilized with a ratio of 80:20. It is mainly used to create films that diffuse transmitted light well, and reduce shadows. This allows plants to receive light across their entire surface and not just in the area of impact. This is very important because it allows plants to make optimal use of any of the light received; uniformly around each of the edges.
