Barrier, Mechanical and Morphological Properties of Biodegradable Films Based on Corn Starch Incorporated with Cellulose Obtained from Pineapple Crowns

This work aimed to develop biodegradable composites formed from corn starch-based films and cellulose extracted from pineapple crown residue. Fibers obtained from the crowns underwent alkaline treatment, followed by bleaching. Cellulose was characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). These analyses verified that the process was effective in isolating cellulose...
