“…The incorporation of natural antioxidants for providing antioxidant and UV-blocking properties has been also observed in Zechang et al [ 23 ], who bonded lignin to cellulose nanocrystals (CNC) to create a biodegradable and active food-packaging material. Natural antioxidants such as lignin or modified lignin [ 24 ] are very effective antioxidants but the main drawback of UV-blocking packaging-materials based on natural compounds is that they usually have high opacity and strong color, which can hinder the perception of the product inside, such as lignin-based materials [ 25 ], and curcumin [ 26 ]. However, in this work, we developed transparent and UV-blocking films enabled by the incorporation of the natural polyphenol—caffeic acid.…”

Applications of cyanoacrylate monomers are generally limited to adhesives/glues (instant or superglues) and forensic sciences. They tend to polymerize rapidly into rigid structures when exposed to trace amounts of moisture. Transforming cyanoacrylate monomers into transparent polymeric films or coatings can open up several new applications, as they are biocompatible, biodegradable and have surgical uses. Like other acrylics, cyanoacrylate polymers are glassy and rigid. To circumvent this, we prepared transparent cyanoacrylate films by solvent casting from a readily biodegrade solvent, cyclopentanone. To improve the ductility of the films, poly(propylene carbonate) (PPC) biopolymer was used as an additive (maximum 5 wt.%) while maintaining transparency. Additionally, ductile films were functionalized with caffeic acid (maximum 2 wt.%), with no loss of transparency while establishing highly effective double functionality, i.e., antioxidant effect and effective UV-absorbing capability. Less than 25 mg antioxidant caffeic acid release per gram film was achieved within a 24-h period, conforming to food safety regulations. Within 2 h, films achieved 100% radical inhibition levels. Films displayed zero UVC (100–280 nm) and UVB (280–315 nm), and ~15% UVA (315–400 nm) radiation transmittance comparable to advanced sunscreen materials containing ZnO nanoparticles or quantum dots. Transparent films also exhibited promising water vapor and oxygen barrier properties, outperforming low-density polyethylene (LPDE) films. Several potential applications can be envisioned such as films for fatty food preservation, biofilms for sun screening, and biomedical films for free-radical inhibition.

“…Polyethylene films, the main films used for packaging fruits and vegetables, are known to be relatively not permeable to water vapor (WVP of about 0.5 × 10 −12 g m −1 s −1 Pa −1 ) . The nanocomposite with the best permeability (1 × 10 −11 g m −1 s −1 Pa −1 ), mechanical and thermal properties, PVA/St/2BC, was used as protective film for a real fruit package (Figure ) and shows a WVP with more than one order of magnitude greater than that of common polyethylene, but its WVP is better than that of many other bioplastics such as St films (1.3 × 10 −9 g m −1 s −1 Pa −1 ) and of the same order of magnitude with some promising PVA‐based materials for packaging application (8.6 × 10 −11 g m −1 s −1 Pa −1 ) …”

Nanocomposite films for food packaging applications were developed using bacterial cellulose (BC) nanofibers in different amount in a poly(vinyl alcohol)/starch (PVA/St) matrix. In search of a better method to reduce the harmful ingredients in food packaging, the cellulose nanofibers were obtained by the mechanical defibrillation of BC pellicles thus avoiding the addition of chemicals in the final packaging material. Improved mechanical performances were obtained starting from just 1% BC nanofibers in PVA/St. Atomic force microscopy images showed a uniform dispersion of BC nanofibers on the surface of nanocomposites. A twofold increase of both tensile strength and modulus was obtained for 2 wt % BC in the composite. BC nanofibers have greatly improved the barrier properties of PVA/St matrix, a twofold increase of water vapor permeability being obtained for only 2 wt % BC nanofibers in the composite film. PVA/St/2BC was proposed as a high potential material for food packaging applications. V C 2017 Wiley Periodicals, Inc. J.Appl. Polym. Sci. 2018, 135, 45800.

The antimicrobial poly(vinyl alcohol) (PVA) films incorporated with nano‐TiO2 were prepared by solution blending‐casting method. The effects of different nano‐TiO2 addition of 0%, 0.5%, 1%, 3%, 5%, and 7% on the characterization of PVA films were studied. The tensile strength of the film incorporated with 0.5% nano‐TiO2 was highest. Compared with the pure PVA film, the oxygen transmission rate, swelling ratio and water vapor uptake ratio of the films containing 0.5%–7% nano‐TiO2 reduced 0.4%–0.8%, 22.82%–81.79%, and 3.59%–10.7%, respectively. The transparency reduced significantly. The thermal stability and antimicrobial activity against Staphylococcus aureus and Escherichia coli were improved. The storage study of macrobrachium rosenbergii indicated that the Shewanella spp., Pseudomonas putida and Aeromonas hydrophila could be inhibited by PVA films added with nano‐TiO2 and their shelf‐life was extended for 1–2 days. It was indicated that there's a good prospect for application of these PVA films in the antimicrobial food packaging. Practical applications Poly(vinyl alcohol) (PVA) is a biodegradability and nontoxicity synthetic polymer, which has been widely used in food packaging materials. This paper proved that the PVA films incorporated with nano‐TiO2 showed good antimicrobial activity. For the application in macrobrachium rosenbergii packaging, it showed that the Shewanella spp., Pseudomonas putida and Aeromonas hydrophila could be inhibited by PVA films added with nano‐TiO2 and their shelf‐life could be extended for 1–2 days. There is a great advantage that the antimicrobial activity of the films could be motivated by UV‐light irradiating before packaging process to avoid that the common active packaging films are in the excited state after prepared. This antimicrobial packaging film could be used as inner layer of the composite packaging film to improve the food quality and prolong the shelf‐life of the food.
