摘要: Properties of gelatin composite films(with 4% glycerol as plasticizer) with different mass concentrations of microfibrillated cellulose (MFC) (0.2-1.0%) were investigated. The prepared composite films with 1.0% MFC showed the highest tensile strength (12.32 MPa) with the lowest water absorption rate (391.1%). The composite films can be dissolved in hot water of 95℃ in less than 5 minutes. However, the addition of MFC had insignificant effect on the heat shrinkage and light transmittance of the resultant composite films.
