Researchers at Northwest A&F University in Shaanxi, China have developed bilayer films made from chitosan and konjac glucomannan that show promise for use in food packaging. The films were prepared using a layer-by-layer casting method and different mass ratios of the two materials were tested. The bilayer films exhibited uniform microstructures, lower swelling degrees, and reduced water vapor permeability compared to pure films. However, the mechanical properties and thermal stability of the bilayer films were slightly compromised. The researchers suggest that further modifications and the addition of active ingredients could enhance the properties of these films for food packaging applications. [Extracted from the article] |
