Summary: The poor properties of native cassava starch film can be improved through dual modification methods, such as hydrogen peroxide oxidation and glutaraldehyde crosslinking. This results in starch films with lower water uptake, better mechanical properties, stiffness, extensibility, and thermal properties. The sequential dual modification process also leads to enhanced performance in terms of swelling power, moisture absorption, and biodegradability.

Summary: Polyacrylonitrile (PAN) films blended with shellac, a biodegradable polymer, were prepared by a simple solution casting method. The miscibility of PAN with shellac polymer was investigated, and the optimal concentration of shellac that resulted in hydrogen bonding between shellac and PAN chain was determined. The introduction of shellac segments facilitated the disruption of the crystalline structure of the PAN chain, leading to a lower oxidation temperature in the PAN/shellac blends film. The optimal PAN/shellac blends film exhibited superior mechanical properties compared to the control PAN film.

Summary: A biodegradable film was prepared using polyvinyl alcohol (PVA), silver chloride (AgCl), and spirulina (Sp). The study investigated the film's surface morphology, mechanical properties, antioxidant and antimicrobial activities, as well as its optical properties. The results confirmed the impact of AgCl and Sp on PVA's structure and showed that Sp increased the film's moisture content and solubility in water. AgCl nanoparticles activated the film's antibacterial property against Escherichia coli and Staphylococcus aureus, while Sp significantly enhanced its antioxidant property. Examination of light transmittance revealed the photochromic property of PVA/AgCl films.

Summary: The extensive use of non-biodegradable plastic products has caused significant environmental issues. Biodegradable polymers offer a solution but face challenges, which researchers are addressing by incorporating bentonite clay into polymeric matrices. However, achieving complete dispersion of nanoclays remains a challenge. Various methods are used to prepare polymer-clay nanocomposites for versatile industrial applications. Combining bentonite clay with other fillers can reduce production costs. This work reviews the development, challenges, and future directions of bentonite clay-based composites with biodegradable polymers.

Summary: Poly (butylene adipate-co-terephthalate) (PBAT) is a biodegradable polymer used in the food packaging industry. A PBAT composite film was prepared using a green approach, with epoxidized soya bean oil (ESO) and encapsulated lignin (Lig)/tannic acid (Ta) as fillers. The addition of ESO-Lig-Ta improved tensile strength, reduced UV transmission, and decreased water vapor and oxygen transmission rate. The composite film showed potential for short-lived fresh food packaging and long-term preservation of dry food products.

Summary: In this study, a biodegradable film based on cress seed mucilage (Muc/MDex/Lut/Al) was modified using maltodextrin (MDex), lutein pigment (Lut) and alumina (Al). The effects of MDex, Lut and Al on the physical and chemical properties of the film were studied using central composite design (CCD). Various techniques such as FTIR, SEM, XRD and TGA were used to investigate the physico-chemical, mechanical, antimicrobial and structural properties of the films. The release rate of lutein from the film was found to depend on the film structure and could be controlled by changing the structure according to specific requirements.

Summary: A process has been developed for fabricating biodegradable polymer films from renewable feedstocks such as agar, alginate, and glycerol, with enhanced mechanical properties. The use of an upsized VFD device operating under confined-mode conditions requires less processing time and energy consumption compared to a standard VFD device, and overcomes difficulties associated with high-viscosity liquid mixtures in terms of jet feed blockage and excessive gelling. The resulting polymer films exhibit stronger mechanical properties and comparable biodegradability to films produced using conventional processing methods.

Summary: This research developed blends of corn starch and PBAT films with the addition of CP biomass. The film with 5.0% CP biomass content showed the best tensile strength, elongation, and water vapor permeability. Ultrasound treatment did not improve the properties of the films. However, the CP biomass in the films provided natural bio-pigmentation's protection against UV light.

Summary: Polysaccharides and proteins were used to produce biopolymeric hydrogels without synthetic crosslinkers. Xanthan gum was employed as a crosslinking agent and cellulose was used as a reinforcing agent. The hydrogels obtained showed smooth surfaces and amorphous polymeric matrices. The hydrogels had pH-dependent swelling and cellulose improved their thermal stability and mechanical properties. This strategy provides an effective method to produce nontoxic hydrogels with promising properties for pharmaceutical or cosmetic applications.

Summary: The food industry has developed starch-poly (adipate co-terephthalate butyl) films with silver nanoparticles produced with Fusarium oxysporum components to control foodborne pathogens. These nanoparticles showed activity against different Salmonella serotypes, including multidrug-resistant strains. However, the migration of silver from the films to chicken meat exceeded the limits allowed by the European Food Safety Authority, indicating the need to improve the technique to prevent harmful concentrations.

Summary: This study investigated the incorporation of tannin into bio-composite biodegradable thermoset materials (BTM) to create an alternative to conventional plastics for environmental applications. The biodegradation of injection molded BTM specimens with and without tannin were evaluated, showing that the inclusion of 1% tannin resulted in reduced molding defects, increased productivity, improved mechanical properties, and reduced biodegradation. The tight interaction between tannin, starch, and lignocellulosic fibers is suggested to delay biodegradation and improve the processability and lifespan of the BTM materials.

Summary: This study aimed to develop a novel colorimetric indicator film using cassava starch, isomalt, and glycerol with 20% wt.% of grape skin extract (GSE) as an indicator of fish freshness. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and RGB color analysis confirmed the homogeneous distribution of GSE in the starch matrix. GSE reduced the thermal stability, k1 value, solubility, swelling values, and %E, while increasing the tensile strength (TS), indicating its plasticizing potential. The pH range compatibility and indicator activity of the GSE-containing film make it an excellent candidate for monitoring fish freshness.

Summary: This study evaluates the use of a bio-based laser-perforated and recyclable SO2-generating liner, alone or in combination with ultra-fast SO2-generating pads, to extend the shelf life of 'Benitaka' table grapes. Results showed that the combination of bio-based and SO2-generating liners, along with ultra-fast SO2-generating pads, effectively controlled gray mold incidence after 45 days of cold storage and 3 days at room temperature. This extended the shelf life of the grapes with low weight loss, fewer shattered berries, and maintained stem freshness.
