“…As a degradable polymer, the improved thermal stability of PVA reduces its unwanted degradation during thermal processing. 41 Figure 13 and composite film was similar to that of the 1% TiO 2 /1% ZnO LDPE. The above account of changes illustrated that the thermal properties of the LDPE and 1% TiO 2 /1% ZnO LDPE basically are close.…”

A novel facilitated transport film was prepared by coating polyvinyl alcohol (PVA)/polyethylene glycol (PEG)/aminated sodium lignosulfonate on TiO2/ZnO‐modified low‐density polyethylene (LDPE). Monoethanolamine (MEA), diethanolamine (DEA), ethylenediamine (EDA), diethylenetriamine (DETA), tetramethylpiperidine amine (TEMP), and acrylamide (AM) were selected to modify sodium lignosulfonate (Ls) for enhancing the selectivity and permeability of CO2/O2. The fabricated Ls were characterized by fourier transform infrared (FTIR), thermogravimetric test (TG), and scanning electron microscopy (SEM). The CO2 permeability and CO2/O2 selectivity were improved with the increase in the amount of amine groups. Compared with the addition of Ls modified by alcohol amine, the composite film has higher selectivity to CO2 after the addition of DETA‐Ls or TEMP‐Ls. The selectivity of the 1:3:3EDA/MEA‐Ls‐g‐AM composite film reached 13.7, and CO2 permeability increased by 5.54 times. The storage test also demonstrated that the composite films have better freshness retention ability. As a result, modified LDPE coated by PVA/PEG/aminated Ls has the potential as an active modified atmosphere packaging material.

“…They are generated from natural animal‐based protein polymer and used in various industries, such as drug delivery and medical application (Bari et al., 2021; Y. Ma et al., 2020; Z. Xu et al., 2019). Nowadays, composite SF nanoparticles have also been used in food packaging, including chitosan reinforced with SF nanodiscs (Ghosh et al., 2021), PLA incorporated with SF and yerba mate nanoparticles (Beltrán, Arrieta, et al., 2021), and PLA–PCL blend reinforced with SF nanoparticles (Chomachayi et al., 2021).…”

Plastic pollution is a significant concern nowadays due to wastes generated from non-biodegradable and non-renewable synthetic materials. In particular, most plastic food packaging material ends up in landfills, creating mass wastes that clog the drainage system and pollute the ocean. Thus, studies on various biopolymers have been promoted to replace synthetic polymers in food packaging and consequently, the high number of research in biopolymers food packaging, especially in the characterization, properties and also the development of the biopolymer. For biopolymer-based food packaging, silk fibroin (SF) has been highlighted because of its biodegradability and low water vapor permeability properties. This review focuses on the different properties of SF films prepared through solution casting and electrospinning for food packaging. Discussions encompassed chemical properties, mechanical properties, permeability, and biodegradability. This review also discussed the studies that used SF as the biomaterial for food packaging.

“…Additionally, chitosan has been mixed with silk fibroin extracted from the waste of the MUGA cocoon to create a new composite coating. The developed material has improved thermal properties and hydrophobicity, extending the shelf-life of bananas by over 7 days at 25 • C, contributing to the maintenance of the initial weight, optical property, and firmness properties [217]. The use of microorganisms for the obtention of biopolymers is a great alternative to obtain compounds with unique properties varying the fermentation conditions.…”

Global demand for minimally processed fruits and vegetables is increasing due to the tendency to acquire a healthy lifestyle. Losses of these foods during the chain supply reach as much as 30%; reducing them represents a challenge for the industry and scientific sectors. The use of edible packaging based on biopolymers is an alternative to mitigate the negative impact of conventional films and coatings on environmental and human health. Moreover, it has been demonstrated that natural coatings added with functional compounds reduce the post-harvest losses of fruits and vegetables without altering their sensorial and nutritive properties. Furthermore, the enhancement of their mechanical, structural, and barrier properties can be achieved through mixing two or more biopolymers to form composite coatings and adding plasticizers and/or cross-linking agents. This review shows the latest updates, tendencies, and challenges in the food industry to develop eco-friendly food packaging from diverse natural sources, added with bioactive compounds, and their effect on perishable foods. Moreover, the methods used in the food industry and the new techniques used to coat foods such as electrospinning and electrospraying are also discussed. Finally, the tendency and challenges in the development of edible films and coatings for fresh foods are reviewed.
