Cassava is a root vegetable that is an excellent source of starch, and it can be used to prepare bio-based packaging materials. The packaging films were developed by blown film extrusion method using 10% and 20% cassava starch, blended with PLA. The water vapor barrier property, and other physico-chemical properties of the packaging films were determined, and it was observed that the film characteristics of PLA and Cassava starch up to 20%, were equally suitable for packaging application to virgin PLA-based film. The biodegradable film developed for MA packaging, had a potential to retain the quality attributes of capsicum up to 12 and 24 days at 25°C and 8°C, respectively as compared to the shelf-life of unpackaged capsicum viz. 4 and 9 days at respective temperatures. Novelty impact statement The film characteristics like haze %, tensile strength, OTR and WVTR parameters for PLA, and 20% cassava starch were found to be 89.68%, 25.16 MPa, 123.92 cc/m2/day, and 217 gm/m2/day, respectively. The physico-chemical characteristics of the developed packaging films were found to be better as compared to other starch and PLA blended film. The outcomes of biodegradable film-based MA packaging were compared to a non-biodegradable film-based MA packaging of capsicum, it was observed that the application of biodegradable film offers a new alternative over the non-biodegradable polymeric film for MA packaging of fresh produce without compromising its quality.
