Customized Black-and-White Mulch Film for Export

Black-and-white PE mulch film features a longitudinal strip design with a central white strip and black side strips, integrating four core advantages: the central white strip transmits light and accumulates heat to promote early root development; the black side strips block light and suppress weeds, reducing labor; the film as a whole maintains soil moisture and temperature to help improve yields—field trials show that potatoes mulched with this film yielded approximately 389 kg more per mu than those with conventional white film, an increase of 15.1%; and the clear black-white boundaries facilitate standardized planting and residual film recovery. Suitable for ridge-cropped crops such as pepper, flue-cured tobacco, and potato, the film is available with customizable width and thickness to match ridge specifications, offering an integrated “dual-effect in one film” mulching solution for early-spring production and fields under high weed pressure.
