Physicomechanical Properties of Edible Film-based Nata de Coco, Acetic Acid, and Chitosan

In recent years, edible films are on the rise as they have a wide variety of advantages, including the use of edible packaging materials over synthetic films. Edible films are environmentally friendly and do not cause environmental pollution. Several researchers have conducted studies on materials for making edible wraps, one of which comes from cellulosic sources. One source of cellulose from food is nata de coco. In this research, edible films based on nata de coco and chitosan were made by mixing and molding methods. The results of the tensile strength test of samples with a variety of 20 mL acetic acid showed a value of 17.805 MPa. This value meets the bioplastic standard (10–100 MPa) and the Indonesian National Standard (SNI) for conventional plastic (24–302 MPa).
