OB masterbatch is often used to increase the whiteness or brightness of mulch films. This can make the mulch film appear more visually appealing and reflective, which can help increase crop yields by optimizing light reflection onto the plants

Mulch films with OB masterbatch can scatter light, leading to more even distribution of light on the plants beneath the film. This can help prevent hotspots and reduce shadowing, leading to more consistent growth and yields. By reflecting more light and heat away from the plants, mulch films with OB masterbatch can help regulate soil and air temperatures. This can be especially beneficial in regions with extreme temperatures, as it can protect the crops from excessive heat.

The increased reflectivity of mulch films with OB masterbatch may deter certain pests that are sensitive to bright light.
