“…Pectin, being a naturally occurring polysaccharide, serves as an energy source for most microorganisms, contributing to the accelerated biodegradation rate. The findings align with the biodegradation analysis of PLA in bilayer film with other polymers, indicating minimal degradation in the PLA layer and substantial degradation in other layered polymers such as protein or polysaccharide polymers [ 62 , 73 ]. Hence, this indicates the biodegradable potential of the optimized bilayer film, demonstrating its ability to naturally decompose in soil without causing harmful effects on land contamination or contributing to landfill problems.…”

“…This aligns with the structural features of pectin from hybrid citrus Kanpei, as reported in the literature by [ 8 ] through FTIR analysis. While the FTIR analysis of PLA films revealed another distinctive absorption peak indicative of its molecular structure, the bands in the range of 3000−2900 cm −1 signify the C-H stretching of methyl groups and the O-H vibration of carboxylic acid [ 35 , 61 , 73 ]. The peak observed at 1748 cm −1 corresponds to the C=O stretching vibration of carbonyl groups [ 62 ], while deformations of -CH 3 CH stretching are observed around 1452 cm −1 and 1360 cm −1 [ 73 ].…”

This study focuses on developing a biodegradable film using a novel hybrid citrus peel pectin. A bilayer approach with PLA was proposed and optimized using Response Surface Methodology (RSM) to complement pectin films’ mechanical and barrier property limitations. The optimized film composition (2.90 g PLA and 1.96 g pectin) showed enhanced mechanical strength with a tensile strength (TS) of 7.04 MPa and an elongation at break (EAB) of 462.63%. In addition, it demonstrated lower water vapor (1.45 × 10−10 g/msPa), oxygen (2.79 × 10−7 g/ms) permeability, and solubility (23.53%). Compared to single-layer pectin films, the optimized bilayer film had a 25% increased thickness, significantly improved water barrier (3806 times lower) and oxygen barrier (3.68 times lower) properties, and 22.38 times higher stretchability, attributed to hydrogen bond formation, as confirmed by FTIR analysis. The bilayer film, effectively protected against UV and visible light, could be a barrier against light-induced lipid oxidation. Moreover, it demonstrated superior seal efficiency, ensuring secure sealing in practical applications. The bilayer pouch containing mustard dressing exhibited stable sealing with no leakage after immersion in hot water and ethanol, making it suitable for secure food pouch packaging.

“…An improved strategy involves the development of PLA/TPS bilayer films with a 50:50 ratio. The interaction process between the two layers is studied and evaluated through physical properties [10]. Last year, Yoksan and Dang investigated the effect of the surfactant Tween 60 (TW) on the compatibility and performance of thermoplastic starch/poly(lactic acid) (PLA)/poly(butylene succinate-co-butylene adipate) blends (TPS/PLA/PBSA) in a proportion of 40:30:30, respectively.…”

The thermal, rheological, mechanical, and barrier properties of flat biopolymeric films processed by extrusion with different proportions of plasticizer and surfactant were evaluated. In the first stage, pellets were developed through twin-screw extrusion using a temperature profile in the ascending step process. These samples were analyzed using rotational rheology analysis to understand the viscoelastic transitions through the behavior of the storage and loss modulus, as well as the incidence of complex viscosity concerning concentration. The interaction among the components was analyzed under infrared spectroscopy after the two processing stages, revealing the miscibility of the mixture due to the action of the surfactant. The degradation temperatures increased by more than 20 °C, generating thermal stability, and the temperatures related to polymer transitions were determined. In the second stage, co-extrusion was carried out using pellets from the blend with a melt flow index (MFI) suitable for this process. The samples TPS50-PLA50-T5 and TPS75-PLA25-T5-A10 presented MFI values of 2.27 and 1.72 g/10 min, respectively. These samples were co-extruded for the production of films, impacting the physical properties. The resistance to traction, Young’s modulus, and elongation showed limited effectiveness of plasticizer and surfactant, with high resistance and elongation values (4.276 MPa and 2.63%) in the TPS50-PLA50-T5 film. Additionally, morphological analysis showed the detailed action of the plasticizer on the regular shapes of threads as a product of deformation during material processing. The barrel properties exhibited limited biopolymer–plastic–tensile miscibility, resulting in different water vapor permeability for the TPS75-PLA25-T5-A10 film on each side (a difference of two orders of magnitude). The contact angle corroborated the effect, with values in each case ranging from 103.7° to 30.3°. In conclusion, we assert that biopolymeric films, when modified with plasticizers and surfactants, can be tailored for various applications within the packaging sector while maintaining control over each film.
