“…First, imbedding of nisin in the NC matrix possibly result in a sustained release of nisin due to the reduction of free nisin available for diffusion, thus allowing for a long-term antimicrobial activity and extended shelf-life [52,53]. Secondly, the NC layer could work as a biocompatible barrier against some possible migrations of hazard chemical compounds from BOPP/LDPE film to the food matrix during storage [54]. In addition, each coated BOPP/LDPE film still reserve its heat-sealing merit because the NC/nisin coatings attached only on the plasma treated areas, leaving untreated margin from the edge of the film available for heat-sealing to form a pouch.…”

The application of nanofibrillated cellulose (NC) films in packaging industry has been hindered by its lack of heat-sealing ability. Incorporation of NC films with the biaxially oriented polypropylene/low density polyethylene (BOPP/LDPE) laminates can take advantage of each material and endow the films with novel functions for food packaging applications. In this study, a coating that consists of NC and nisin was applied onto a cold plasma treated BOPP/LDPE film to fabricate a novel active packaging with an improved oxygen barrier performance and an added antimicrobial effect. The results showed that cold plasma treatment improved the surface hydrophilicity of BOPP/LDPE films for better attachment of the coatings. NC coatings significantly enhanced oxygen barrier property of the BOPP/LDPE film, with an oxygen transmission rate as low as 24.02 cc/m 2 •day as compared to that of the non-coated one (67.03 cc/m 2 •day). The addition of nisin in the coating at a concentration of 5 mg/g caused no significant change in barrier properties but imparted the film excellent antimicrobial properties, with a growth inhibition of L. monocytogenes by 94%. All films exhibit satisfying mechanical properties and transparency, and this new film has the potential to be used as antimicrobial and oxygen barrier packaging.

“…In another study, Honarvar et al. (2017) developed an antimicrobial packaging consisting of PP films coated with carboxymethyl cellulose (CMC) incorporated with Zataria multiflora essential oil. The developed multilayer film inhibited pathogens and also possessed improved mechanical and water vapor barrier properties.…”

“…Apart from XPS, Fourier transform infrared spectroscopy (FTIR) gives information about chemical structure and functional groups of the polymers (Chen et al., 2018). Atomic force microscopy can be employed in the analysis of surface morphology such as changes occurring in the surface roughness when subjected to different treatments (Honarvar et al., 2017). Microscopic analysis of a multilayer film surface can be done using scanning electron microscopy (SEM) to help in the detection of swelling, delamination, surface cracks, and holes after processing (Marangoni Júnior, Cristianini, Padula, & Anjos, 2019).…”

In recent years, with advantages of versatility, functionality, and convenience, multilayer food packaging has gained significant interest. As a single entity, multilayer packaging combines the benefits of each monolayer in terms of enhanced barrier properties, mechanical integrity, and functional properties. Of late, apart from conventional approaches such as coextrusion and lamination, concepts of nanotechnology have been used in the preparation of composite multilayer films with improved physical, chemical, and functional characteristics. Further, emerging techniques such as ultraviolet and cold plasma treatments have been used in manufacturing films with enhanced performance through surface modifications. This work provides an up-to-date review on advancements in the preparation of multilayer films for food packaging applications. This includes critical considerations in design, risk of interaction between the package and the food, mathematical modeling and simulation, potential for scale-up, and costs involved. The impact of in-package processing is also explained considering cases of nonthermal processing and advanced thermal processing. Importantly, challenges associated with degradability and recycling multilayer packages and associated implications on sustainability have been discussed.

“…With this aim, biopolymer matrices can serve as an excellent carrier of antimicrobial agents, as noted in the above section. In fact, several works have been carried out in the last several decades concerning the antimicrobial efficacy of essential oils, natural extracts, and bacteriocins incorporated into biopolymer matrices (Cardoso et al., ; Honarvar et al., ; Moghimi, Aliahmadi, & Rafati, ; Rezaeigolestani et al., ). Nevertheless, although their bactericide and fungicide properties have been largely studied, little information exists in the literature about how biopolymers could act as carriers of virucide compounds and how they behave in a food package or edible coating.…”

Gastroenteritis and hepatitis, caused by human noroviruses (HuNoVs) and hepatitis A virus (HAV), respectively, are the most common illnesses resulting from the consumption of food contaminated with human enteric viruses. Food-grade polymers can be tailor designed to improve food safety, either as novel food-packaging materials imparting active antimicrobial properties, applied in food contact surfaces to avoid cross-contamination, or as edible coatings to increase fresh produce's shelf life. The incorporation of antimicrobial agents into food-grade polymers can be used to control the food microbiota and even target specific foodborne pathogens to improve microbiological food safety and to enhance food quality. Enteric viruses are responsible for one fifth of acute gastroenteritis cases worldwide and the development of food-grade polymers and biopolymers with antiviral activity for food applications is a topic of increased interest, both for academia and the food industry, even though developments are still limited. This review compiles existing studies in this widely unexplored area and highlights the potential of these developments to improve viral food safety.
