Abstract

Tri-layer films based on glycerol-plasticized sodium caseinate film (SC) as the middle layer and two outer layers of mechanically recycled poly(lactic acid) (RPLA) were successfully developed. Additionally, the internal RPLA-based layer was loaded either with 1 or 3 wt% of lignocellulose nanoparticles extracted from yerba mate waste (YMNs) to obtain antioxidant-active packaging formulations. YMNs were also surface modified with a surfactant to increase the interfacial adhesion and improve their dispersion into the polymeric matrix. The tri-layer system composed of YMNs loaded nanocomposites (RPLA/SC/RPLA-YMN1 and RPLA/SC/RPLA-YMN3) exhibited an improved oxygen barrier compared to the non-reinforced system counterpart (RPLA/SC/RPLA). The high water vapor permeability of SC was reduced in tri-layer systems, ascribed to the protection of the middle SC layer by the hydrophobic RPLA layers at both sides. The improved performance of all these properties was ascribed to the good adhesion between PLA and SC layers, ascribed to hydrogen bonding interactions. Furthermore, the obtained tri-layer structures showed effective antioxidant ability for fatty food, as it was demonstrated by release studies conducted in a fatty food simulant and further analysis of the radical-scavenging activity showing good antioxidant properties (RPLA/SC/RPLA-YMN1 = 36.8 +/- 2.5 GA mg/dm(2) film and RPLA/SC/RPLA-YMN3 = 81.1 +/- 2.5 Gallic Acid mg/dm(2) film). Finally, the tri-layer films were disintegrated under composting conditions in 17 days. Thus, the results show the potential of the mechanical recycling process of PLA as a sustainable alternative to revalorizing PLA waste, while the revalorization of yerba mate waste shows its interest by easily providing the materials with antioxidant properties. Finally, the tri-layer bio-based and biodegradable active formulations resulted in interesting materials for fatty foodstuffs.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Express Polymer Letters due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2022, it was in position 34/86, thus managing to position itself as a Q2 (Segundo Cuartil), in the category Polymer Science. Notably, the journal is positioned en el Cuartil Q2 para la agencia Scopus (SJR) en la categoría Chemical Engineering (Miscellaneous).

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.04. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)
