The present research aimed to develop biodegradable mulch films that could resolve the environmental problem in agriculture. The research also compared the properties of transparent and black commercial mulch films. Blended films were prepared by blown-film extrusion, heating at 170 °C, and rotation at 55 rpm. The results revealed that the appearance of FTIR spectra were shown as functional groups of PBAT, described at 1710 cm-1 and 1267 cm-1, which corresponds to carbonyl groups in ester linkage and C-O in ester linkage, respectively. The presence of O-H carboxylic acids, attributed within the range 910-950 cm-1. The films containing 10% PLA loading showed peaks from 937 to 1712 cm-1, more than films containing 20% PLA loading. The carbon black contained in the biodegradable film could interrupt the mobility of the polymer chain, leading to decreased Tm, while the incorporation of carbon black in biodegradable mulch films could increase the tensile properties of blends. |
