Nowadays, the use of polymers is enhancing day by day. Through to not biodegradability in nature, they accumulate and contaminate the environment. One of the recent methods to solve this issue is using biodegradable polymers. Low-density polyethylene was chosen as a symbol and its film was prepared by an extruder in the lab. Starch, Oxo material, polylactic acid, and their mixture were used as biodegradable material and their influence on the physical and mechanical properties of low-density polyethylene were studied. Results indicated that using starch resulted in a significant decrease of mechanical properties for the low-density polyethylene, while Oxo material and polylactic acid caused a low change in the mechanical properties.
