The work aims to prepare a kind of edible packaging paper film with cassava residue as raw material and test its properties to prepare low-cost, excellent-performance and environmental-friendly packaging paper film. Dietary fiber was extracted by physical-enzymatic hydrolysis method, and then was degassed, cast and dried by adding complex thickeners, plasticizers, etc. to obtain the environmental-friendly edible packaging film. Next, the properties of the film were characterized and analyzed by mechanical property test, thickness measurement, and moisture permeability measurement. Under experimental conditions, when the mass ratio of dietary fiber to distilled water was 1∶25, the mass of compound thickener (sodium carboxymethyl cellulose: sodium alginate=62∶38, mass ratio) accounted for 3% of the mass of dietary fiber solution, the mass of glycerol accounted for 1.6% of the mass of dietary fiber solution, and the mass of beeswax accounted for 0.6% of the mass of dietary fiber solution, the film had the best properties, with tensile strength and water vapor permeability of 5.19 MPa and 0.712 g•mm/(m2•d•kPa), respectively. Low-cost cassava residues can be used to prepare edible packaging film with good performance, which can reduce environmental pollution, save resources and promote resource recycling.
