ABSTRACT:
A method of mulching comprising mulching plants or soil with antistatic films of a synthetic polymer obtained by the method consisting essentially of continuously printing over at least part of the surface of at least one side of the film of synthetic polymer with aluminum powder by suspending in solvent a composition consisting essentially of aluminum powder and a polyamide resin, setting the suspension down onto the film, and permitting the solvent to evaporate. The films obtained have a surface resistivity of less than 10.sup.10 ohms/cm. The mulching of plants with these films prevents virus degeneration of the plants by virus-carrying aphides, and the mulching of the soil limits the increase of soil temperature in warm environments.
