Biocomposites have gained attention in the packaging industry due to their potential as sustainable alternatives to conventional synthetic materials. In this study, novel cotton incorporated poly (lactic acid)/ thermoplastic starch biocomposites were developed for packaging applications using in short shelf life products the extrusion method. Pelletized samples obtained by extrusion were stamped from plates obtained by compression and were characterized through measurement of density, hardness, contact angle and water absorption, as well as Fourier transform infrared spectroscopy (FTIR), thermal analysis and scanning electron microscopy (SEM). No significant changes in the density results were observed. A slight increase in the hardness of formulations in relation to the PLA was associated with the presence of cotton fiber in biocomposites. The FTIR results revealed physical interaction of PLA, TPS and cotton fiber. By DSC analysis, for all formulations the melting exhibited only one peak, suggesting good homogeneity and interaction among the components, as observed by TG/DTG results, and corroborating SEM analysis. The biocomposite PLA/TPS/Cotton 85/10/5 wt.% displayed greater increase in water absorption than both 95/5/0 and 90/5/5 wt.% formulations, which can be attributed to the increase in starch proportion, confirming the contact angle results. The hydrophilic tendency corroborated the biodegradation process in the packaging end-of-life.

“…Table 6 shows the values of D Shore hardness of PLA and its composites. The pure PLA hardness showed a lower value than others in the literature 59–61 . The hardness of PLA increased with both AF additions, with a tendency for hardness increase occurring almost linearly.…”

“…The pure PLA hardness showed a lower value than others in the literature. [59][60][61] The hardness of PLA increased with both AF additions, with a tendency for hardness increase occurring almost linearly. Because of that, the PLA/10% AF presented the highest Shore hardness value, with a significant increase of 23% compared to pristine PLA and 11.1% compared to PLA/5% AF, indicating that the hardness improvement is due to the insertion of AF in the polymer matrix.…”

Additive manufacturing (AM) of eco‐friendly biocomposites has been growing recently to obtain green fillers capable of reducing bioplastic costs without compromising the material processability and performance. This paper aims to study the effect of using different Agave America fiber volume ratios on the morphological, chemical, and thermal properties, contact angle, and hardness of poly(lactic) acid (PLA) filament for 3D printing. Sustainable biofilaments of PLA filled with 10 and 5 wt% of Agave Americana fiber were prepared in a thermokinetic mixer and extruded in a machine, and then used to print testing samples using fused deposition modeling (FDM) 3D printer. Biofilaments were characterized using scanning electron microscopy (SEM), thermogravimetry (TGA), differential scanning calorimetry (DSC), and Fourier‐transform infrared spectroscopy (FTIR) techniques. The addition of fiber did not significantly influence the biofilament's diameter and density compared to pure PLA. On the other hand, it influenced printed biofilaments' thermal stability and morphological characteristics. The biocomposites developed have shown enhancement in their shore hardness. Thus, the use of Agave Americana fiber reinforced in a PLA matrix did not compromise its thermal properties, nor its processability and printability, which could open the possibility of future research with a biocomposite with higher fiber content and an environmentally friendly alternative over traditional filler materials.
