“…The mechanical properties of all films were summarized in Table . The TS value of PVA‐GTE 0% film was 28.53 MPa, which was comparable to the results reported by other authors for pure PVA films (Bonilla, Fortunati, Atarés, Chiralt, & Kenny, ; Costa‐Júnior, Barbosa‐Stancioli, Mansur, Vasconcelos, & Mansur, ; Giannakas et al, ). The TS increased significantly as the GTE ratio increased in the film ( p < .05), while elongation at break reduced evidently.…”

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.

“…The preparation of the CS/G solution was made by mixing 20% w/v G and a 2% w/v CS solution and stirring until homogenization (Giannakas et al, ). For the preparation of the CS/PVOH solution, a hot aquatic PVOH solution was added into 2% w/v CS solution and it was stirred until homogenization (Giannakas et al, ). The PVOH content was fixed at 20% w/w (Giannakas et al, ).…”

“…The second materials were two different nanoclays, NaMt and OrgMt (Fasihnia, Peighambardoust, & Peighambardoust, ; Peighambardoust, Beigmohammadi, & Peighambardoust, ). Several publications refer to the improvement of the CS mechanical behaviour via the incorporation of nanoclays into CS because of its mechanical properties (Giannakas, Grigoriadi, Leontiou, Barkoula, & Ladavos, ; Lavorgna, Piscitelli, Mangiacapra, & Buonocore, ), thermal stability (Darder & Ruiz‐hitzky, ; Giannakas et al, ; Katerinopoulou, Giannakas, Grigoriadi, Barkoula, & Ladavos, ; Wang et al, ), functional properties (Darder, Colilla, & Ruiz‐Hitzky, ), barrier properties (Giannakas et al, ; Rhim, Hong, Park, & Ng, ; Vicente, ; Vlacha et al, ), and water solubility (Vicente, ; Giannakas, Patsaoura, Barkoula, & Ladavos, ). In all cases, the reported concentration of the clay component was in the range of 1%–5% w/w.…”

The globally increasing needs for food quantity and quality led industries to invest in packaging methods that enhance the shelf life and quality of foods. Also, the effort to avoid the use of petrochemical or chemical derivatives in the production‐chain increased the exploitation of by‐products and biomass. In this work, the raw materials such as montmorillonite (Mt), the chitosan (CS) which is a sea‐food byproduct, and the natural essential oil extract thyme oil (TO) were combined via two different methods for the development of an advanced nanocomposite active packaging film for foods. In the first method, the so‐called “Solution‐Blending” (SB), a CS/TO solution was blended with sodium–montmorillonite (NaMt) or organomodified‐montmorillonite (OrgMt). In the second method, the so‐called “ModifiedClay” (MC), the TO was adsorbed into NaMt or OrgMt and the produced hybrid was added to CS. The tests indicated that nanocomposite films which were prepared via the MC method are promising materials for active packaging films. Practical applications Nowadays, a lot of effort is spent on finding advanced food conservation methods which extend shelf time, increase quality, and vanish the food odor problems. This study shows that films which are prepared via the modified clay method exhibit high antioxidant behavior and high antimicrobial activity against Escherichia coli. Also, tests on under‐vacuum packaged chicken breast fillets exhibit low lipid oxidation values. Thus, these films/pads are promising for active packaging applications of meat and other food products.
