“…The antioxidant effect of the films was analysed according to Colín-Chávez et al, 36 [40][41][42][43] The thickness of the films with free β-carotene did not present significant difference when compared with control CSF. But, significant difference (P < .05) was observed with the addition of β-carotene nanocapsules in relation to CSF, with increase the thickness of 0.123 to 0.142 to 0.157 mm for the films BCN2%, BCN5%, and BCN8%, respectively.…”

β-Carotene may represent an excellent natural antioxidant, and nanoscale encapsulation may contribute to development of a new technique for addition of antioxidants in active packaging.The objective of this work was to develop active biodegradable films with addition of free β-carotene or β-carotene-loaded lipid-core nanocapsules and to evaluate the interaction with the polymeric matrix. The addition of free β-carotene led to a decrease in the mechanical properties of films, result of their hydrophobic character and less interaction with the matrix.β-Carotene nanocapsules caused the increase of colour intensity of films, elongation at rupture, and less light transmission, with the gradual increase according to increase in concentration. Films with β-carotene nanocapsules presented greater protection of sunflower oil, with lower formation of oxidation products. The lower stability of free antioxidant led to behavior similar to control film, with less oxidation protection. The addition of nanocapsules can provide better interaction with the structure, since the encapsulated carotenoid exhibits solubility in aqueous medium and present better distribution, without altering the rapid biodegradability and thermal stability of films. The results show that encapsulated bioactive compounds can be used as hydrophobic natural antioxidants and added in active biodegradable packages for maintaining food safety and extending the shelf life.

“…Accordingly, the polymer strands are banded together by relatively weak intermolecular attractions, which need much less strength to break than MD film (Phua, Chow, & Mohd Ishak, 2011). Several previous researchers (Battisti et al, 2017;Chang et al, 2019;Sun, Lu, Qiu, & Tang, 2017) have also documented the lower mechanical strength of the TD in the developed film than the strength of the MD.…”

A multilayer film containing star anise essential oil and thymol coating layers (SAEO and TH, respectively), with insect repellent and antimicrobial properties, has been developed using bar coating and adhesive lamination processes. Our previous study reported the in vitro activities of this polypropylene film (PP)/SAEO/polyethylene terephthalate film (PET)/TH/low‐density polyethylene film (LDPE) multilayer film. The current study focused on demonstrating the morphological, optical, and mechanical properties of the film, and evaluating its in vivo activities when used as a bread packaging material. The developed film was 15.03% thicker and 1.86% less transparent than the control film (without active agent coating layers: PP/PET/LDPE). While the color values of the developed film were slightly different from the control film, both films appeared similar to the naked eye. The tensile strength in the developed film was somewhat lower than that of the control film, while both films had statistically comparable values for elongation at break. During storage of sliced bread packaged in the developed film, the film both deterred insects from approaching toward and impeded the growth of microorganisms in the bread. These results suggest the potential applicability of the developed film as an active food packaging material with insect repellent and antimicrobial activities. Practical Application A multilayer film incorporated with insect repellent and antimicrobial coating layers was applied in sliced wheat bread packaging. The developed film effectively inhibited approaches of stored‐product insects to packaged bread and growth of microorganisms on the bread surface. It can be used as an active food packaging material that improves the safety and shelf‐life of foods.

“…Developing active packaging films with control release property has been the goal of many recent researches. Several technologies were employed to control the release rate of active agents, such as blend (Castro, Dopico, Pernas, & Manuel, ; Han, Lu, & Ge, ; Lacoste, Schaich, Zumbrunnen, & Yam, ; Wattananawinrat, Threepopnatkul, & Kulsetthanchalee, ), microcapsule (Liu et al., ; Wen et al., ), porous material used as adsorption carrier (Gargiulo et al., ; Park, Hwang, Yoon, Lee, & Lee, ; Sun, Lu, Qiu, & Tang, ), and multilayer films (Guiga et al., ; Mastromatteo, Barbuzzi, Conte, & Nobile, ; Müllers, Wahl, & Pinto, ; Pasqual, Bermúdez, Aucejo, Catalá, & Gavara, ; Pavaloiu, Stoica‐guzun, Stroescu, Jinga, & Dobre, ). The controlled release system of multilayer films originated from the technology of lay by lay in the pharmaceutical field, which was introduced into the development of controlled release packaging later (Han, ).…”

The polypropylene/poly(vinyl alcohol)/polypropylene (PP/PVA/PP) multilayer active films with controlled release property were developed, of which the intermediate PVA layer was incorporated with 4% (w/w) tea polyphenols (TP) and the microporous PP films with different pore size were used as the internal controlled release layer. The SEM results showed that each layer of these films was agglutinated tightly. With increasing pore size from 171.05 to 684.03 µm, there were little effect on the films’ color and opacity, the tensile strength (TS) and elongation at break (EAB) decreased slightly, the gas barrier (O2 and water vapor) property of the film reduced faintly, the time of achieving the release equilibrium in 50% ethanol decreased from 75 hours to 30 hours. The diffusion coefficient for the films increased with the increase of pore size, from 2.06 × 10−11 cm2/s to 8.06 × 10−11 cm2/s, suggesting that the release rate of TP increased as the pore size increased. The results were indicated that its release rate could be controlled by adjusting the size of pore. The films also exhibited different antioxidant activities due to their different release profiles of TP. It showed promise for developing the controlled release active packaging film based on this concept. Practical Application Controlled release packaging is propitious to extension of food shelf life. The microporous polypropylene films with different pore size used as the internal layer of polypropylene/poly(vinyl alcohol)/polypropylene (PP/PVA/PP) multilayer active films was proved that the release rate of tea polyphenols in the intermediate PVA layer released from the films into the food simulant can be controlled by adjusting the size of pore in this study. It showed a good prospect for using microporous or perforation‐mediated film as the internal layer of multilayer film to develop the controlled release active packaging film for food packaging.
