The shelf-life of grapes is reduced due to infection by various pathogens and mechanical damage, which consequently limits their availability on the market and results huge economic losses. Active packaging films are expected to overcome this problem. In this study, packaging films (CMC-Gly-PMA) were developed using wheat straw-based carboxymethyl cellulose (2 %), glycerol (30 % w/w of CMC) and polymalate (0.9 %) to prolong the grape shelf-life. With regard to physical properties of films, TS, EB, OP and WVP were 28.4 MPa, 142.1 %, 8.52 mmol/kg and 0.55 × 10
