Special Issue Information

Dear Colleagues,

Packaging plays an important role in protecting products as they go from the manufacturer to the consumer. So, the packaging industry is steadily growing but still faces many challenges. Consumer awareness toward environmental issues, in particular, has imposed the necessity to find sustainable materials to replace oil-derived polymers in the field. The development of new packaging materials with “green” characters is now an urgent need of our society. Apart from that, it is also expected for packaging with novel functionalities, which increase not only the shelf life of products but also their safety and quality in bringing convenience and benefits to consumers. This Special Issue caters to the needs of chemical and chemical engineers, material scientists, food chemists, and microbiologists in the area of packaging. 

Review articles, full papers, and technical papers on this topic are all welcome.

As an organic−inorganic thermoelectric composite material, a flexible, reduced graphene oxide (rGO)/silver sulfide (Ag2S)/methyl cellulose (MC) film was fabricated by a two-step method. Firstly, a rGO/Ag2S composite powder was prepared by a chemical synthesis method, and then, the rGO/Ag2S/MC composite film was prepared by a combined screen printing and annealing treatment process. The rGO and rGO/Ag2S composite powders were evenly dispersed in the rGO/Ag2S/MC composite films. A power factor of 115 μW m−1 K−2 at 520 K was acquired for the rGO/Ag2S/MC composite film, which is ~958 times higher than the power factor at 360 K (0.12 μW m−1 K−2), mainly due to the significant increase in the electrical conductivity of the composite film from 0.006 S/cm to 210.18 S/cm as the test temperature raised from 360 K to 520 K. The as-prepared rGO/Ag2S/MC composite film has a good flexibility, which shows a huge potential for the application of flexible, wearable electronics. Full article

Anthocyanin has attracted increasing attention due to its superior biological activity. However, the inherently poor stability of anthocyanin limits its practical applications. In this study, a fast and straightforward method was developed to improve the stability of anthocyanin. Cellulose acetate ultrafine fiber-loaded anthocyanin (CA@Anthocyanin UFs) was prepared by robust electrospinning, and the potential application of cellulose acetate ultrafine fibers (CA UFs) as a bioactive substance delivery system was comprehensively investigated. The experimental results showed that CA@Anthocyanin UFs had protective effects on anthocyanin against temperature, light, and pH. The results of the artificially simulated gastric fluid (pH = 2.0) indicated that the CA@Anthocyanin UFs had a controllable release influence on anthocyanin. A 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging assay suggested that the CA@Anthocyanin UFs still had an excellent antioxidant activity similar to anthocyanin. This work demonstrated the potential application of robust electrospinning-constructed cellulose acetate ultrafine fibers in bioactive substance delivery and controlled release systems, as well as its prospects in green packaging due to the nature of this environmentally friendly composite.
