Summary: In this study, starch/powdered activated carbon composite films were prepared by incorporating different amounts of PAC into a starch matrix using the solvent casting method. The mechanical properties of the biopolymer film were examined, and it was found that the barrier properties decreased with the increase in filler content. The results did not show a monotonic dependence of the mechanical parameters on PAC content, except for the maximum strain, which decreased with increasing additive amount.

Summary: Composite films made of pea starch and ε-polylysine as the matrix, with glycerol and sodium alginate as the plasticizers, were investigated. The properties of these films, including rheological and mechanical properties, Fourier transformed infrared spectroscopy, water vapor and oil permeability, microstructure, thermogravimetry, and antimicrobial properties, were analyzed. The results showed that the mass ratio of St/PL greatly influenced the properties of the films, with higher PL content leading to decreased tensile strength, increased fracture elongation, increased permeability, and reduced oil resistance. Moreover, the antimicrobial properties of the films improved with higher mass ratios of PL, with the strongest inhibition observed against B.subtilis.

Summary: In this study, chitosan/acetylated starch composite films containing cinnamon and clove essential oils were fabricated via a solution-casting technique. The effects of essential oil concentration on the physical, mechanical, barrier, microstructural, and antimicrobial properties of the films were evaluated. The films incorporated with essential oils displayed excellent barrier and antimicrobial properties, making them a promising option for edible food packaging applications.

Summary: The study demonstrates that agar plays a significant role in the structure and properties of starch/agar composites, and optimal performance can be achieved with a certain ratio of starch to agar. These composite polysaccharide films could be utilized in biodegradable packaging and biomedical applications due to their tailored mechanical properties and surface hydrophilicity.

Summary: By adding nano-silica, the tensile strength of poly(butylene adipate-co-terephthalate)/thermoplastic hydroxypropyl starch (PBAT/TPHSg-SiO2) composite films is significantly improved, with a 35% increase in horizontal tensile strength and a 21% increase in vertical tensile strength after adding 4 phr of nano-silica. When the content of TPHSg-4SiO2 is 40%, the composite films have horizontal and vertical tensile strengths of 9.82 and 12.09 MPa, respectively, and the elongation at break exceeds 500%. Electron micrographs show that TPHSg-4SiO2 is well dispersed in PBAT and exhibits a bi-continuous phase structure at a TPHSg-4SiO2 content of 40%. The blowing PBAT/TPHSg-4SiO2 composite films effectively reduce the cost and still show better mechanical properties, suitable for packaging applications.

Summary: The study investigated the effects of different gelatin Bloom values on the properties of starch/gelatin-beeswax films fabricated by extrusion blowing, finding that higher Bloom values enhanced physicochemical properties and influenced water solubility and thermal stability. This indicated that gelatins with appropriate Bloom values could be utilized to produce films with desirable properties.
