“…In fact, Halim et al [56] reported that chitosan with high molecular weight has reduced biodegradation whereas, with low molecular weight, biodegradation rate is enhanced. Besides that, Rachmawati et al [57] showed that chitosan film degrades naturally in soil in a period ranging from 72–87 days.…”

<abstract> This study aimed to formulate sodium lauryl sulfate cross-linked chitosan beads and sodium alginate-chitosan films for designing a dressing that would shorten the healing time of skin wounds. <italic>Teucrium polium</italic> extract-loaded chitosan-sodium lauryl sulfate beads (CH-SLS) and chitosan-alginate (CH-ALG) films were prepared and characterized by using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM). The swelling properties of the CH-SLS beads were also analyzed in a water solution. The obtained <italic>Teucrium polium</italic> extract-loaded CH-SLS beads and CH-ALG films (TBF) were further incorporated into the commercial adhesive dressing. This TBF wound dressing was then investigated for evaluation of its wound healing potential in the mice using the excision wound model. Healing was assessed by the macroscopic appearance and the rate of wound contraction during 8 days. On day 4, the TBF-treated wounds exhibited 98% reduction in the wound area when they were compared with healing ointment, elastic adhesive dressing, and untreated wounds which were exhibited 63%, 43%, and 32%, respectively. Furthermore, the application of TBF dressing reduced skin wound rank scores and increased the percentage of wounds contraction. These results demonstrate that TBF dressing improves considerably the healing rate and the macroscopic wound appearance at a short delay and this application may have therapeutic benefits in wound healing. </abstract>

Nations all over the world are imposing ban on single-use plastics, which are difficult to recycle and lead to creations of nonsustainable and nondegradable piles. To match the requirement in the market, suitable food packaging alternatives have to be developed that are biodegradable and environment-friendly. The current work is designed for the fabrication of a novel nanocomposite by blending xanthan gum in a chitosan matrix and reinforcing it with ZnO nanoparticles, through a solution casting method. Surface morphology of the film was investigated through field emission scanning electron microscopy, along with energy-dispersive X-ray spectroscopy mapping, and characterized through thermogravimetric analysis, Fourier transform infrared (FTIR) spectroscopy, mechanical testing, and ultraviolet spectroscopy. FTIR spectroscopy analysis corroborated the interaction between the components and the H-bond formation. Polyelectrolyte complex formation materializes between the oppositely charged chitosan and xanthan gum, and further nanoparticle incorporation significantly improves the mechanical properties. The synthesized nanocomposite was found to have increases in the tensile strength and elongation at break of pure chitosan by up to 6.65 and 3.57 times, respectively. The transmittance percentage of the bionanocomposite film was reduced compared to that of the pure chitosan film, which aids in lowering the oxidative damage brought on by UV radiation in packed food products. Moreover, the film also showed an enhanced barrier property against water vapor and oxygen gas. The film was totally biodegradable in soil burial at the end of the second month; it lost almost around 88% of its initial weight. The fabricated film does not pose a threat to the environment and hence has great potential for application in the future sustainable food packaging industry.

“…The development and application of biodegradable starch-based materials have attracted increasing attention due to the well-recognized issues of oil shortage and the growing interest in easing the environmental burden due to extensive use of petrochemically-derived polymers. Twelve Andean crops (tubers, legumes, roots, and fruits) were used for manufacturing starch films [141]. The authors used the cellulose film as the control one.…”

The accumulation of high amounts of petro-based plastics is a growing environmental devastation issue, leading to the urgent need to innovate eco-safe packaging materials at an equivalent cost to save the environment. Among different substitutes, starch-based types and their blends with biopolymers are considered an innovative and smart material alternative for petrol-based polymers because of their abundance, low cost, biodegradability, high biocompatibility, and better-quality film-forming and improved mechanical characteristics. Furthermore, starch is a valuable, sustainable food packaging material. The rising and growing importance of designing starch-based films from various sources for sustainable food packaging purposes is ongoing research. Research on “starch food packaging” is still at the beginning, based on the few studies published in the last decade in Web of Science. Additionally, the functionality of starch-based biodegradable substances is technically a challenge. It can be improved by starch modification, blending starch with other biopolymers or additives, and using novel preparation techniques. Starch-based films have been applied to packaging various foods, such as fruits and vegetables, bakery goods, and meat, indicating good prospects for commercial utilization. The current review will give a critical snapshot of starch-based films’ properties and potential applicability in the sustainable smart (active and intelligent) new packaging concepts and discuss new challenges and opportunities for starch bio composites.
