“…Adding hydrophobic components into a polymeric matrix could generate a barrier effect on the transmission of water molecules if they were homogeneously scattered in the film. [27] Similar conclusions were observed in LDPE film with α-tocopherol, [28] starch-sodium caseinate films containing α -tocopherol [29] PVA film incorporated with clove oil [24] and PVA film incorporated with green tea extract. [30] In the case of nanoclay, the increase of C15A wt.…”

“…At all concentrations of C15A, the increase in α-tocopherol content resulted in the decrease of tensile strength which can explain that the stronger interactions of PE intermolecular were partially replaced by weaker PE and α-tocopherol interactions in the film matrix. [23][24] On the other hand, an increasing of α-TOC content resulted in increases elongation at break. α-tocopherol is an oily compound acting as a lubricant in the PE structure and promoting the chain sliding during the extension.…”

“…In the case of the pure PVA spectrum, the characteristic absorption peaks at 3266, 1326 and 1085 cm −1 were caused by the O–H stretching vibration, CH–OH bending vibration and C–O stretching vibration, respectively. Additionally, the absorption peaks at 2919 and 1416 cm −1 were attributed to the asymmetric stretching vibration and bending vibration of C–H groups respectively [ 16 , 28 ]. With the addition of LDHs@TA-Ti, the weak absorption peak of ester groups in TA appeared near 1697 cm −1 .…”

Inspired by complexation and mussel adhesion of catechol groups in tannic acid (TA), organophilic layered double hydroxides (LDHs@TA-Ti) were synthesized by forming a one-pot assembled TA-titanium (Ti) dual network coating on the surface of layered clay for the first time. LDHs@TA-Ti/poly(vinyl alcohol) (PVA) nanocomposites were prepared by the solution casting method. The results show that TA-Ti(IV) and TiO2 coordination compounds are simultaneously formed due to hydrolysis of titanium tetrachloride and complexation of TA in aqueous solution. Upon TA-Ti coatings onto the surface of LDHs, the antibacterial rate of LDHs@TA-Ti is up to 99.98%. Corresponding LDHs@TA-Ti/PVA nanocomposites also show outstanding antibacterial properties. Compared with pure PVA, LDHs@TA-Ti/PVA nanocomposites show a 40.9% increase in tensile strength, a 17.5% increase in elongation at break, a 35.9% decrease in oxygen permeability and a 26.0% decrease in water vapor permeability when adding 1 wt % LDHs@TA-Ti. UV transmittance (at 300 nm) of LDHs@TA-Ti/PVA nanocomposites decrease by 99.4% when the content of LDHs@TA-Ti reaches 3 wt %. These results indicate that PVA matrix incorporated with LDHs@TA-Ti could be used as a potential active packaging material to extend the shelf life of food products.

“…Also, the packaging material made of poly(vinyl alcohol) films incorporated with clove oil exhibited antioxidant properties (Chen, Xu et al, ). The authors observed that PVA films incorporated with clove oil showed effective antioxidant activities in vapor phase, which increased with the increasing content of CO, by inhibiting the bacterial growth and lipid oxidation of the Trichiurus haumela .…”

Packaging is an intermediary product between producers and consumers. The most important role of packaging is to ensure the highest quality and safety of packaged products and to extend their shelf life. Given that microbiological contamination is a problem for manufacturers and consumers due to the fact that it reduces the quality of packaged products and poses a health risk, this work describes solutions related to antimicrobial packaging. More attention is given to antioxidant packaging that releases synthetic or natural antioxidants to prevent food oxidation. The purpose of intelligent packaging is to monitor the quality of food products, as well as inform consumers and food producers of their quality. Therefore, many studies focus on developing time temperature indicators. The work also discusses radio frequency identification (RFID), whose application has a lot of advantages, such as identifiability, management of stored products, labor cost savings and ensuring the quality and safety of packaged products. Practical applications The current trends related to food safety and the growing expectations of the consumers lead to changes in the approach to food packing. Active and intelligent packaging has been present on the global packaging market for years, and scientists all over the world are looking for novelties related to this kind of packaging. For these reasons, this work focuses on presenting new solutions in active and intelligent packaging.
