Special Issue Information

Dear Colleagues,

With the development of the concept of sustainable food, food safety and quality maintenance have been given more and more attention. The use of polymer materials for food packaging is the development trend of today’s food technology and material science. For example, the combination of various plasticizing materials to control gas permeability, edible films, polymer materials combined with essential oils, smart packaging, polymer material modification, the use of environmentally friendly materials, etc., are in accordance with the characteristics and purposes of different foods and agricultural products. Polymer application research is definitely incredibly diverse at present.

Therefore, this Special Issue further focuses on the Characterization of Polymer Food Packaging Materials and expects to present more relevant and innovative research results.

Biodegradable film packaging made from thermoplastic starch (TPS) has low mechanical performance and high water solubility, which is incomparable with synthetic films. In this work, Aloe vera (AV) gel and plasticized soluble potato starch were utilised to improve the mechanical stability and water solubility of TPS. Dried starch was mixed with glycerol and different AV gel concentrations (0% to 50%). The TPS + 50% AV gel (30 g TPS + 15 g AV gel) showed the best improvement compared to TPS alone. When compared to similar TPS films with AV gel added, this film is stronger and dissolves better in water. Mechanical qualities improved the tensile strength and Young’s modulus of the TPS film, with 1.03 MPa to 9.14 MPa and 51.92 MPa to 769.00 MPa, respectively. This was supported by the improvement of TPS water solubility from 57.44% to 46.6% and also by the increase in decomposition temperature of the TPS. This promises better heat resistance. The crystallinity percentage increase to 24.26% suggested that the formation of hydrogen bonding between TPS and AV gel enhanced crosslinking in the polymeric structure. By adding AV gel, the TPS polymeric structure is improved and can be used as a biodegradable food-packaging film. Full article
