The extensive use of plastic has resulted in negative impacts on the environment. Hence, it is necessary to get environmentally friendly packaging material alternatives to plastic derived from biopolymers. This study aimed to make films from the starch derived from avocado seeds and coconut fiber and determine the mechanical properties of the films. The methods used were extraction of starch from avocado seeds, process of making films and characterization of mechanical properties of films. The raw materials used were variations of starch (2%, 4%, 6%, and 8%), 2 ml of sorbitol, and 1 g of cellulose fiber from coconut. The various tests were conducted to determine mechanical properties of films such as tensile strength, elongation percentage, and elasticity. Test results show the optimum value of tensile strength is 2,016 MPa, the elongation percentage is 12.38% and obtained at the composition of 6% of starch. Thus, it can be concluded that the addition of starch can improve the mechanical properties of films.
