“…The mechanical properties of the films are essential to resist external shocks and maintain the integrity of the food. 36 Tensile tests were performed on each sample film, as shown in Figure 3a. The tensile strength and Young's modulus of the CMC@Ag film were not significantly higher compared to the pure CMC film.…”

Among all of the plastic pollutants, cling packaging films pose a particularly complex problem due to their high consumption, poor reusability, difficulty in recycling, and nondegradability. Despite many efforts by researchers to develop alternatives to plastic cling films, none of the alternatives have been satisfactory. Here, cellulose-based active packaging films that are degradable, renewable, and reusable were prepared by one-pot green synthesis of silver-based metal−organic frameworks on carboxymethyl cellulose (Ag-2MI@CMC). The preparation process is simple (water solvent system with normal temperature and normal pressure). The Ag-2MI@CMC composite film exhibits better performance than commercial PE films, including (1) better mechanical properties and antifog performance, Ag-2MI@CMC film has a high tensile strength of about 61 MPa, while that of commercial PE films is only about 35 MPa, (2) excellent antimicrobial properties, including bacteria and mold, while commercial PE films did not exhibit any antibacterial properties, (3) better fruit preservation than commercial PE cling films, (4) high natural degradability (complete degradation takes only about 45 days, during which time the commercial PE film does not degrade at all), and (5) renewable and reusable more than five times, the recycled Ag-2MI@CMC film still maintains good mechanical strength and fruit preservation effect. Given the low raw material cost and superior performance of the composite film, one-pot green synthesis of cellulose-based active packaging films may be a suitable solution to solve the environmental challenges brought by the high volume of the plastic packaging films.

“…The optimal content of KGM was 0.3%, where a homogeneous and compact structure was formed ( Table 3 ) [ 63 ]. Interestingly, adding β-cyclodextrin (β-CD) increased the number of double-helical junction zones between starch segments particularly AM chains enhancing hydrogen bonding thereby enhance the strength of the molecular network [ 64 ]. The incorporation of β-CD into the composite film helped to reduce the phase separation, promote the interaction between the polysaccharide chains and enhancing the mechanical and barrier properties.…”

High Amylose-Based Bio Composites: Structures, Functions and Applications

As biodegradable and eco-friendly bio-resources, polysaccharides from a wide range of sources show steadily increasing interest. The increasing fossil-based production of materials are heavily associated with environmental and climate concerns, these biopolymers are addressing such concerns in important areas such as food and biomedical applications. Among polysaccharides, high amylose starch (HAS) has made major progress to marketable products due to its unique properties and enhanced nutritional values in food applications. While high amylose-maize, wheat, barley and potato are commercially available, HAS variants of other crops have been developed recently and is expected to be commercially available in the near future. This review edifies various forms and processing techniques used to produce HAS-based polymers and composites addressing their favorable properties as compared to normal starch. Low toxic and high compatibility natural plasticizers are of great concern in the processing of HAS. Further emphasis, is also given to some essential film properties such as mechanical and barrier properties for HAS-based materials. The functionality of HAS-based functionality can be improved by using different fillers as well as by modulating the inherent structures of HAS. We also identify specific opportunities for HAS-based food and biomedical fabrications aiming to produce cheaper, better, and more eco-friendly materials. We acknowledge that a multidisciplinary approach is required to achieve further improvement of HAS-based products providing entirely new types of sustainable materials.

“…This promoted a more compact HCS/ KGM film. These materials were transparent and exhibited a reduced moisture formation, with an improved water vapor permeability compared with the native films [ 113 ]. Similarly, Huang et al reported the fabrication of a novel food packaging material based on molecularly imprinted polymers (MIP), using β-CD as a monomer.…”

Using cyclodextrins (CDs) in packaging technologies helps volatile or bioactive molecules improve their solubility, to guarantee the homogeneous distribution of the complexed molecules, protecting them from volatilization, oxidation, and temperature fluctuations when they are associated with polymeric matrices. This technology is also suitable for the controlled release of active substances and allows the exploration of their association with biodegradable polymer targeting to reduce the negative environmental impacts of food packaging. Here, we present a fresh look at the current status of and future prospects regarding the different strategies used to associate cyclodextrins and their derivatives with polymeric matrices to fabricate sustainable and biodegradable active food packaging (AFP). Particular attention is paid to the materials and the fabrication technologies available to date. In addition, the use of cutting-edge strategies, including the trend of nanotechnologies in active food packaging, is emphasized. Furthermore, a critical view on the risks to human health and the associated updated legislation is provided. Some of the more representative patents and commercial products that currently use AFP are also listed. Finally, the current and future research challenges which must be addressed are discussed.
