“…Importantly, the physical properties (including the mechanical strength and water vapour permeability) of the films can be tuned easily by manipulating the film constituents 14 . Such high tunability in the properties of a polymeric film has also been observed in a film generated from a cellulose derivative 15 . The UV-shielding capacity and wettability of the film can be altered simply by changing the molecular weight of the derivative or the concentration of the film-forming solution 15 .…”

Smart packaging materials enable active control of parameters that potentially influence the quality of a packaged food product. One type of these that have attracted extensive interest is self-healable films and coatings, which show the elegant, autonomous crack repairing ability upon the presence of appropriate stimuli. They exhibit increased durability and effectively lengthen the usage lifespan of the package. Over the years, extensive efforts have been paid to the design and development of polymeric materials that show self-healing properties; however, till now most of the discussions focus on the design of self-healable hydrogels. Efforts devoted to delineating related advances in the context of polymeric films and coatings are scant, not to mention works reviewing the use of self-healable polymeric materials for smart food packaging. This article fills this gap by offering a review of not only the major strategies for fabrication of self-healable polymeric films and coatings but also the mechanisms of the self-healing process. It is hoped that this article cannot only provide a snapshot of the recent development of self-healable food packaging materials, but insights into the optimization and design of new polymeric films and coatings with self-healing properties can also be gained for future research.

A novel fluorescent, hydrophobic cellulose-based UV-blocking film was developed via chemical surface modification. Cellulose acetoacetate (CAA) film was firstly regenerated by acetyl acetylation of cellulose in a homogeneous system. Based on this esterified film with acetoacetyl groups, both 1,4-dihydropyridine (DHP) fluorescent ring and hydrophobic octadecylamine (ODA) were bonded to cellulose chains through Hantzsch reaction and the formation of enamine bond, by using a one-pot process under room temperature. The resulting film exhibited bright fluorescent and excellent UV-blocking properties (shielding almost 100% UV), which are very stable even being exposed to long periods of UV radiation, harsh temperature treatment and different solvents. In addition, this film has good hydrophobic feature (the contact angle reach up to 112°). This work provided a facile and environmentally friendly strategy to fabricate multifunctional cellulose-based film, which had great application potential in the field of UV protection, fluorescent materials, packaging and cover materials for greenhouse.

“…The merging of high-barrier packaging components with vacuum or modified-atmosphere food packaging appears to be another promising methodology [189][190][191]. Even though it is technically difficult to eliminate all oxygen, this process can diminish the amount of oxygen in the package [192].…”

Natural antioxidants, such as phenolic compounds, carotenoids, vitamins, and microelements, are predominant in fruits, vegetables, herbs, and spices. The accretion interest of consumers in utilizing natural ingredients in food products, have accelerated the appeal for functional “natural” operations. Therefore, understanding how natural antioxidants especially nano-antioxidants, and their delivery systems when used in antioxidant polymers for food packaging are extracted from natural sources, would help prevent oxidation reactions. Given the increasing role of natural antioxidants in the daily lives of today’s communities, a continuous synthesis of relevant literature is pertinent. To supplement existing information, recent advances in nano-related natural antioxidants, their extraction methods and applications in the food industry are discussed in this current work. Insightfully positioning antioxidants within the nano-delivery systems, this current work reveals the potential nanotechnology provides in enhancing the absorption of antioxidants in human metabolic systems.
