Title: Stretched plastic film for agricultural use

Abstract: There is disclosed the provision of a plastic film for covering soil for use in cropping or covering a frame for greenhouse effect. At least part of the plastic film has been stretched beyond its yield point prior to application. In alternative forms, the film undergoes a secondary stretch to form a predetermined pattern of weakness in certain localized areas of the film. The film may be photodegradable and biologically degradable to accelerate decomposition of the film when exposed to the elements.
