Food packaging has to preserve food products, not only providing protection against mechanical factors, but also antioxidant and antimicrobial protection. This article describes the effects of PBS film modification with two sea buckthorn extracts (chloroform extract supercritical CO2 extract) at different concentrations (1 or 5 g per 100 polymer). The films were tested determine effect active additive on optical properties, moisture sorption, properties (against Escherichia coli, Staphylococcus aureus, Candida albicans). improved free radical scavenging significantly (up 41.13 ± 1.31% for PBS-CO2 0.05) reduced number microorganisms studied (more than a 6000-fold reduction E. 1400-fold in S. aureus 1200-fold C. ability block UV radiation was dependent concentration polymer matrix. No significant changes noticed FTIR spectra. obtained appear be potential materials products special protective properties.

Abstract This study investigates the synthesis of potato starch elastomers reinforced with silicon dioxide (SiO 2 ) and citric acid as a crosslinking agent to enhance their mechanical barrier properties. Surface morphology analysis using optical microscopy revealed that pure films had uneven surfaces. However, higher SiO concentrations increased roughness, while crosslinked displayed smoother surfaces overall. Water vapor transmission rates (WVTR) indicated native were highly hydrophilic, incorporation significantly reduced WVTR 17% (30% lower than film), enhancing Tensile strength testing tensile by 25%, further but decreased elasticity 15%. little impact on degradation rates, delayed microbial growth, extending film longevity 20%. Biocompatibility assays SiHa, HT-29, HEK 293 cell lines varying degrees confluency. Films both showed improved confluency (20% higher) compared containing only . alone resulted in highest (95% viability), suggesting its significant role biocompatibility. eco-friendly approach demonstrates substantial advancements properties, offering potential applications diverse biomedical industries.

ABSTRACT This study introduces a novel approach to addressing the water resistance limitations of poly(vinyl alcohol) (PVA)‐based biodegradable films by developing ternary blend system incorporating tung oil (T) and natural rubber (R), forming PTR films. Photocrosslinking, combined with thermal redox catalytic systems, facilitated creation enhanced network structures, as confirmed FTIR analysis, particularly at oils conjugated double bonds. Dynamic mechanical analysis (DMA) revealed significant shifts in glass transition temperatures ( T g ), signifying crosslink density interconnectivity between components. The resulting demonstrated remarkable improvements resistance, evidenced higher solid remain percentages, reduced absorption, significantly lower vapor permeability (WVP). Mechanical properties, including tensile strength Youngs modulus, improved up 150% (from 6.6 MPa PT0R15‐r‐np 16.3 PT0R15‐r‐p30) 870% PT0R15‐r‐p30), respectively, due formation robust structures. Contact angle measurements moisture content further underscored hydrophobic barrier properties. These findings establish photocrosslinked sustainable high‐performance option for packaging applications, offering practical advantages such processing production times.
