“…This observation is supported by the data presented in Figures d,e. Reduced levels of water vapor and oxygen lead to a decrease in cellular respiration, thereby slowing down the maturation process . Specifically, the CFL-2 film demonstrated a decrease in WVTR by 840.61 g/m 2 ·24 h and a reduction in the level of the OTR by 0.10 m 3 /m 2 ·24 h·0.1 MPa when compared to the CFL-0 film.…”

“…Whereas, extending the films from the background board with a distance of 1.5 cm, the “Shanghai University” patterns through all the films are very fuzzy. On the other hand, the preservation films with UV blocking, particularly in UVA (320–400 nm) and UVB (280–320 nm) regions, can significantly improve product quality and sensory attributes . As illustrated in Figure b,c, all of the films possess high visible light transparency and high UV light resistance simultaneously.…”

Due to the perishable nature and limited shelf life, it is crucial to develop highly efficient techniques for fruit preservation while avoiding the use of environmentally hazardous materials. Herein, the ecofriendly oxidized cellulose nanofibers (OCNF) with an optimized solid content (1.0 wt %) was utilized to stabilize d-Limonene to form an oil-in-water Pickering emulsion. By incorporating the Pickering emulsion into chitosan (Cs) solution, fully biobased Cs/OCNF@d-Limonene coatings were successfully obtained via a simple solvent casting method. Thanks to the physical cross-linking and hydrogen bond reaction between OCNF and Cs matrix, the films exhibited high transmittance, high haze, exceptional mechanical properties, and the ability to effectively shield 96.5% UVB and 69.3% UVA radiation. Most importantly, the inclusion of d-Limonene exhibited a remarkable enhancement in the inhibition zones against E. coli and S. aureus, and an outstanding 72.5% improvement in antioxidation properties. These outstanding film properties make the Cs/OCNF@d-Limonene coatings ideal as conformal films for fruit protection, which can effectively reduce the fruit water loss rate, delay ripening, prevent oxidation and microbial invasion, and significantly extend the shelf life of fruits. The well-designed coatings present a promising, cost-effective, and sustainable alternative to conventional plastic packaging materials for fruit protection.

“…Water vapor permeability (WVP) is another indicator that reflects the water permeability of the composite films [ 23 , 24 ]. It is reported that packaging materials with low WVP can inhibit water loss and reduce nutritional loss while maintaining the complete appearance of the food itself to extend its storage time [ 25 , 26 ]. In general, the WVP value of packaging films is affected by the properties of composite films, film structure and environmental conditions.…”

There is an ongoing trend to design new kinds of food packaging materials with excellent properties which are environmentally friendly enough. The aim of this study was to prepare and characterize egg white protein (EWP)-based composite films with and without ε-polylysine (Lys), as well as to compare their physical–chemical properties, structural properties, degradation and antibacterial properties. The results showed that with the addition of Lys, the composite films showed a decreasing tendency of the water permeability due to the enhanced interaction between proteins and water molecules. As indicated by the structural properties, stronger cross-linking and intermolecular interactions happened with increasing concentration of Lys. In addition, the composite films presented excellent antibacterial activities against Escherichia coli and Staphylococcus aureus on chilled pork in the presence of Lys. Therefore, our prepared films might be used as a freshness-keeping material with an application in meat preservation. The biodegradation evaluation demonstrated that the composite films were environmental-friendly and have potential applications in the field of food packaging.

“…Also, ε-polylysine is a well-known antibacterial polymer. , The addition of lignin to cellulose-based films can improve the UV-shielding, hydrophobicity, and antioxidant properties of the films . Incorporation of lignin into the cellulose-based films followed by surface functionalization by ε-polylysine provided dual antioxidant/antimicrobial films . The cellulose/lignin films were prepared by dissolution of a mixture of wood pulp and phenolated lignin in AmimCl ionic liquid and then immersing in water for removal of the AmimCl through phase inversion strategy.…”

The packaging of food plays a crucial role in food preservation worldwide. However, traditional packaging systems are passive layers with weak efficiency in protecting the food quality. Therefore, packaged foods are gradually spoiled due to the oxidation and growth of microorganisms. Additionally, most of the commercial packaging films are made of petroleum-based materials which raise environmental concerns. Accordingly, the development of eco-friendly natural-derived active packaging systems has increased the attention of scientists. Cellulose as the most abundant polysaccharide on earth with high biocompatibility, no toxicity, and high biodegradability has extensively been applied for the fabrication of packaging films. However, neat cellulose-based films lack antioxidant and antimicrobial activities. Therefore, neat cellulose-based films are passive films with weak food preservation performance. Active films have been developed by incorporating antioxidants and antimicrobial agents into the films. In this review, we have explored the latest research on the fabrication of antimicrobial/antioxidant cellulose-based active packaging films by incorporating natural extracts, natural polyphenols, nanoparticles, and microparticles into the cellulose-based film formulations. We categorized these types of packaging films into two main groups: (i) blend films which are obtained by mixing solutions of cellulose with other soluble antimicrobial/antioxidant agents such as natural extracts and polyphenols; and (ii) composite films which are fabricated by dispersing antimicrobial/antioxidant nano- or microfillers into the cellulose solution. The effect of these additives on the antioxidant and antimicrobial properties of the films has been explained. Additionally, the changes in the other properties of the films such as hydrophilicity, water evaporation rate, and mechanical properties have also been briefly addressed.
