Summary: Different plasticizers were found to significantly affect the mechanical properties, transparency, and water resistance performance of potato flour films. Ethylene glycol plasticized films showed the highest tensile strength and lowest elongation at break, while xylitol, sorbitol, ethylene glycol, and glycerol plasticized films were the most transparent. Films with PEG200 and urea had higher moisture content and water vapor permeability, while PEG400 and propylene glycol plasticized films showed differences in water solubility and water contact angle. Plasticizer type played a crucial role in improving the properties of potato flour films.

Summary: This article reports on the synthesis and evaluation of starch nanoparticles (SNP) as nanofillers to improve the properties of polyurethane (PU) films using ultrasound-assisted acid hydrolysis. The study found that the addition of SNP to the PU matrix increased the roughness of the surface, lowered water vapor permeability, increased the glass transition temperature, and enhanced the microbial barrier properties of the film. Furthermore, an increase in the SNP content also improved the toughness and barrier properties of the film.

Summary: A layered biodegradable composite based on bacterial nanocellulose (BNC) and polyhydroxyalkanoate (PHBV) was produced to improve its barrier properties for food packaging. The PHBV coating significantly reduced water vapor permeability and increased hydrophobicity, but decreased the stiffness of the composite. The mechanical and barrier properties of the layered composite were considered suitable for food packaging applications.

Summary: Biodegradable polymers have attracted significant attention due to their environmentally friendly compostability. However, challenges remain for their practical application in packaging, particularly in addressing gas/moisture barrier issues. Various strategies have been researched for decades to overcome these challenges, such as chain architecture tailoring, crystallinity, melt blending/multi-layer co-extrusion, nanotechnology, and surface coating. This review focuses on improving the oxygen/water vapor barrier properties of biodegradable polymers and discusses the limitations of current methods and potential solutions.

Summary: The effect of sodium hydroxide concentrations on the morphology, mechanical properties, and water barrier properties of carboxymethyl rice starch films was investigated. Increasing NaOH concentrations resulted in higher degree of substitution of CMSr powders, leading to changes in morphology. The water solubility, elongation at break, and water vapor permeability of the films increased as NaOH concentrations increased, while the water contact angle, melting temperature, and tensile strength decreased.

Summary: In this study, the physicochemical properties of a composite polymer material based on starch-chitosan-pluronic F127 were modified by storing it for 16 months under ambient conditions. The results showed that the incorporation of pluronic F127 can help prevent the retrogradation of starch, but higher concentrations can reduce wettability. After storage, the materials exhibited surface modification, color change, increased solubility, and a slight increase in stiffness.

Summary: The preparation and characterization of biodegradable films based on starch-PVA-nanoclay by solvent casting were reported in this study. Nanoclay dispersion in the polymeric matrix of starch-PVA is improved by sonication, leading to better physicochemical properties. Incorporation of 0.5% w/v sonicated nanoclay into the matrix starch-PVA results in a film with improved properties, while concentrations higher than 1.0 w/v saturate the polymer matrix, affecting the physicochemical properties negatively.

Summary: Thermoplastic biofilms were produced from achira starch, chitosan, and nanoclays through solvent-casting, and the influence of sonication time on their properties was investigated. Longer sonication times resulted in stronger intermolecular interactions, improved mechanical properties, and more homogeneous materials. The films with 20 minutes of sonication exhibited satisfactory tensile strength and elongation, increases of 154% and 161% respectively. These materials showed lower hydrophilicity, making them potential candidates for coatings or packaging in the food industry.
