“…Based on these facts, it was believed that the intermolecular interactions between DAC and β-CD were responsible for the improved mechanical strength of the films, which also supported the results of FT-IR. The TS of the DAC-CD/Cur films was much higher than that of a pure poly(vinyl alcohol) film (16.0 MPa) or chitosan–graphene oxide composite films (10.9–33.7 MPa). , …”

Antibacterial packaging film mediated by photodynamic inactivation (PDI) is a new concept in food industry. The objective of this study was to fabricate a green 2,3-dialdehyde cellulose (DAC)-based antimicrobial film with PDI potency by incorporating the β-cyclodextrin/curcumin (β-CD/Cur) complex as a photosensitizer. The PDI-mediated films were characterized by evaluating the surface morphology, chemical structure, light transmittance, mechanical properties, photochemical and thermal stability, and water solubility. The results showed that the DAC-CD/Cur films were soluble in water and mechanically strong with a tensile strength of 63.87 MPa and an elongation break of 1.32%, which was attributed to the formation of hydrogen bonds between DAC and β-CD/Cur molecules. Meanwhile, the composite films possessed a good light transmittance but impeded the penetration of ultraviolet light and efficiently delayed the degradation of curcumin. More importantly, the PDI-mediated films exhibited a broad-spectrum ability to kill Listeria monocytogenes, Vibrio parahaemolyticus, and Shewanella putrefaciens in pure culture. Notably, they also potently inactivated these harmful bacteria on ready-to-eat salmon with a maximum of ∼4 Log CFU/g (99.99%) reduction after 60 min irradiation (13.68 J/cm2). Therefore, the PDI-mediated DAC-CD/Cur films are novel and promising antimicrobial food packaging films in food industry.

“…The second event of weight loss (Δ w 2 ) appeared at T d2 of 173.30°C and 256.93°C, indicating the degradation film the polymer matrix. The third stage of weight loss, Δ w 3 = 32.84%‐35.58%, and T d3 of 314.34‐324.48°C were observed, mostly associated with the thermal decomposition of high‐molecular‐weight protein fractions . As can be seen, the T d and Δ w increased, but the residue (%) decreased with the increase of TiO 2 NPs content from 0.5% to 2% in CH films.…”

“…With the temperature improving, the T d of film samples underwent three distinct stages. The thermal degradation of first stage weight loss for all film samples at 4.22%‐6.59% was observed with degradation temperature ( T d1 ) of 50.84°C‐64.74°C, mostly attributed to the evaporation and crystallization of water adsorbed in the film . The second event of weight loss (Δ w 2 ) appeared at T d2 of 173.30°C and 256.93°C, indicating the degradation film the polymer matrix.…”

[63,64] As can be seen, the T d and Δw increased, but the residue (%) decreased with the increase of TiO 2 NPs content from 0.5% to 2% in CH films. The result revealed that CH films incorporated with TiO 2 NPs significantly improved the thermal stability of CH films compared to the control film, which can be ascribed to the better thermal stability of TiO 2 when compared with CH and to good interaction between TiO 2 and CH.…”

In the present research, titanium dioxide (TiO2) nanoparticles (NPs) were prepared by using sol‐gel technique, and the phase structure and morphology of obtained TiO2 NPs were characterized by using X‐ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The XRD patterns of the TiO2 NPs indicated the formation of anatase phase. A new nanocomposite film has been developed by solvent casting method from collagen hydrolysate (CH) and TiO2 NPs at different concentrations for use in packaging industry. Fourier transform infrared (FTIR) spectra showed the intermolecular reactions between CH and TiO2 NPs in the films. SEM micrographs revealed a clear dispersion of TiO2 NPs on the surface of the films especially at low concentrations. Thermal analyses showed that after incorporation of TiO2 NPs in polymer matrix, heat susceptibility of films were changed and weight loss of films was decreased. The results revealed that incorporation of TiO2 NPs significantly decremented water vapor permeability (WVP), water solubility, and elongation at break (EAB) of the films, whereas tensile strength (TS) significantly incremented. The findings pointed out that TiO2 NPs can be successfully incorporate to the CH films and the reutilization of CH in nanocomposite films will be a promising alternative material in non‐food packaging industry.

Antistatic packaging film plays an important role in protecting sensitive electronic components from the damage of electrostatic discharge (ESD) during transportation and application. Considering the antistatic property and environmental friendliness of polyvinyl alcohol (PVA), PVA was chosen as matrix to prepare PVA/carbon fiber (CF) composite film via melt casting and asynchronous biaxial stretching. The addition of CF made more perfect conductive pathway formed in system, thus improving the electric property of the composite precursor sheet. And the subsequent biaxial stretching further promoted the cross arrangement of CF as well as the orientation of PVA molecular chains, so endowed the stretched composite film with excellent mechanical, antistatic and water‐resistant properties. When CF content was 5 wt% and the stretching ratio was 3.0 × 3.0, the tensile strength, volume resistivity and water contact angle of the composite film reached 69.4 MPa, 1.07 × 105 Ω·cm, and 74.7° respectively, which met the requirements of electrostatic dissipation packaging. This work highlights the structural evolution of PVA/CF composites under biaxial stretching and spurs the devising of antistatic packaging materials.
