Since plastics are being widely used in agriculture, horticulture and packaging, meeting this requirement becomes increasingly dificult (specially in IRAN as one of the biggest manufacturers of polyethylene materials).So, attention is focussed on production  of  biodegradable polyethylene. In this study, some different formulations based on starch and urea for making polyethylenes which are biodegradable in soil and moist media, have been investigated. The compounds produced are injection molded, and tested under natural conditions and their biodegradability has been studied. It has been thus possible to produce a biodegradable low-density polyethylene which is environmentally biodegradable material that is suitable for agriculture and packaging applications.
