“…The WVTR of the PVA films incorporated with different concentrations of GTE was given in Figure . The WVTR of pure PVA film was in the order of those previous researches reported for PVA films (Gharoy Ahangar, Abbaspour‐Fard, Shahtahmassebi, Khojastehpour, & Maddahi, ; Marcos, Aymerich, Monfort, & Garriga, ; Wang et al, ). The WVTR of PVA films was slightly reduced when GTE was added into the films, which was reduced from 1.87 (g·m −2 ·d −1 ) for PVA‐GTE 0% film to 1.03 (g·m −2 ·d −1 ) for PVA‐GTE 2% film.…”

“…PVA is a humidity sensitive polymer and water molecules can be absorbed to interact with the polymer chains, which caused reduction of intermolecular interactions and increase of flexibility (Marcos et al, ), and as a consequence the water molecular diffusion through film was accelerated. It is well known that polyphenolic compounds contain many hydrophobic groups (Gharoy Ahangar et al, ), like benzene ring group, which improves hydrophobic property of the PVA film for incorporation of GTE. The water molecular diffusion was weakened as hydrophobic property of PVA films was improved.…”

Active packaging film with functions of moisture-absorbing and antioxidant activity was developed based on poly(vinyl alcohol) (PVA) incorporated with green tea extract (GTE). The effects of GTE concentrations of 0, 0.5, 1, 1.5, and 2% on the physical, structural, and antioxidant properties of PVA films were investigated. The PVA film containing 2% GTE had lower moisture absorbing efficiency relatively and better antioxidant activity through DPPH radical-scavenging ability experiment. A packaging system of GTE-incorporated PVA films was applied to package dried eel and quality of dried eel was evaluated during storage. The result showed that dried eel packed with GTE-incorporated PVA films showed lower weight change, peroxide value and TBARS value during storage than that packed without PVA films or with PVA films but no GTE. The PVA film containing 2% GTE showed the best quality protective effectiveness to prevent the dried eel from absorbing moisture and oxidizing of lipid. Practical applicationsPoly(vinyl alcohol) (PVA) is a synthetic polymer that is widely used in packaging applications because of its excellent film forming, biodegradability, good mechanical, and gas barrier properties.The present study evidenced that the PVA films incorporated with GTE showed good quality protective effectiveness to prevent the dried eel packed with these films from absorbing moisture and oxidizing of lipid. This active packaging film could be used as inner layer or intermediate layer in the composite packaging film system to improve the storage quality of moisture-sensitive and high-fat food. Based on this concept, the moisture-absorbing agents and antioxidant can be incorporated into the packaging structures to develop an active multifunctional food packaging material potentially to remove or reduce moisture inside the food packaging system instead of desiccants and preservative added in the food.

“…ZnO is a multifunctional nanoparticle approved by the Food and Drug Administration (FDA) and is used in several foods and cosmetics [ 30 ]. ZnO is also a very well-known nanofiller and has already been applied to fabricate numerous biopolymer-based films owing to its exceptional antimicrobial action, non-cytotoxicity, and high stability [ 31 , 32 , 33 ]. It has previously been shown that the incorporation of ZnO in biopolymers enhances their physical properties (mechanical and barrier) and provides the composite films with potent antimicrobial activities [ 30 , 34 , 35 ].…”

Cellulose Nanofiber-Based Nanocomposite Films Reinforced with Zinc Oxide Nanorods and Grapefruit Seed Extract

Here, we report the fabrication and characterization of cellulose nanofiber (CNF)-based nanocomposite films reinforced with zinc oxide nanorods (ZnOs) and grapefruit seed extract (GSE). The CNF is isolated via a combination of chemical and physical methods, and the ZnO is prepared using a simple precipitation method. The ZnO and GSE are used as functional nanofillers to produce a CNF/ZnO/GSE film. Physical (morphology, chemical interactions, optical, mechanical, thermal stability, etc.) and functional (antimicrobial and antioxidant activities) film properties are tested. The incorporation of ZnO and GSE does not impact the crystalline structure, mechanical properties, or thermal stability of the CNF film. Nanocomposite films are highly transparent with improved ultraviolet blocking and vapor barrier properties. Moreover, the films exhibit effective antimicrobial and antioxidant actions. CNF/ZnO/GSE nanocomposite films with better quality and superior functional properties have many possibilities for active food packaging use.

“…[ 13 – 16 ]. In addition, numerous studies have reported the preparation and the antibacterial efficacy of PVA films containing plant extracts, silver nanoparticles or zinc oxide nanoparticles [ 17 – 22 ]. However, when bacteria start to form biofilms they become resistant and conventional antibiotics do not eradicate biofilms from the surfaces where they formed [ 8 ].…”

The unique photothermal properties of non-spherical gold nanoparticles under near-infrared (NIR) irradiation find broad application in nanotechnology and nanomedicine. The combination of their plasmonic features with widely used biocompatible poly(vinyl alcohol) (PVA) films can lead to novel hybrid polymeric materials with tunable photothermal properties and a wide range of applications. In this study, thin PVA films containing highly photothermally efficient gold nanostars (GNSs) were fabricated and their properties were studied. The resulting films displayed good mechanical properties and a pronounced photothermal effect under NIR irradiation. The local photothermal effect triggered by NIR irradiation of the PVA-GNS films is highly efficient at killing bacteria, therefore providing an opportunity to develop new types of protective antibacterial films and coatings.
