Issues related to the performance and processing remain a challenge when managing materials from renewable and natural resources. This study aims to show the potential of biopolymer film composite from cassava starch and carboxymethylcellulose to replace the synthetic coating and the area of studies are its barrier, mechanical and chemical properties. Fourier Transform Infrared analysis identified that only film containing CMC could act as antimicrobial agent carrier. The biopolymer film coated on the kraft paper with the presence of 30% v/v glycerol and 10% w/w CMC had the highest tensile strength, at 15 MPa. The film-coated paper also exhibited a hydrophobic surface with reduction of the contact angle from 104.957deg; to 96.337deg; for 120 seconds. Meanwhile, addition of turmeric oil into developed BF 3 showed insignificant changes in tensile strength but reduced the contact angle to less than 907deg;. Thus, the formulated coating materials can be used as an alternative green technology for paper coating used in food industry and can be classified as a form of active packaging. © Published under licence by IOP Publishing Ltd.
