Resumo

The pandemic scenario has impacted the consumption pattern, increasing the use of single-use materials. This work presents the development of active films for application in food packaging products. Poly(butylene adipate-co-butylene terephthalate) (PBAT) films, reinforced with nanocellulose (2 % by weight) and chitosan nano -capsules containing essential oils (EO), were developed using two different EO and different capsules content (1 %, 3 %, and 5 % by weight). The films were investigated by thermal analysis (TGA), mechanical properties, X -Ray diffraction (XRD), water vapor permeability (WVP), contact angle, oil release, and antimicrobial tests. The films presented excellent thermal stability and showed increased mechanical properties compared with pristine films. The film's crystallinity corroborated these results, indicating that the fibers and capsules promoted a nucleating effect during film formation. The WVP and contact angle results indicated that EO's hydrophobicity impacted the film's surface properties. The antimicrobial activity of the films was evaluated against Escherichia coli (E. coli), and it was observed inhibition of bacterial growth for all films containing EO. These results show a promising application for extending food products' shelf life in new formulations and using environmentally friendly materials. (AU)
