The carboxymethyl potato residue edible packaging films are successfully prepared by solution mixing method with the carboxymethyl potato starch residue as the main raw material and plasticizer and reinforcing agent as the modified additives and the Mechanical properties, blocking performance, the instant performance and sealing properties are studied. The results show that the thickness of the edible packaging film is 90±3 μm, the strength of extension is 7.88±0.03 MPa, the instant of time is 25±1 s, the water vapor permeability is 0.218±0.006 g·mm /(m2·d·kPa), the oxygen permeability is 2.011± 0.007 cm3·cm/(cm2·s·Pa), the through oil coefficient was 0 g·mm/(m2·d) and the sealing strength is 7.47±0.01 N/15 mm while the optimum additive amount of the carboxymethyl potato residue is 2.0 g, the additive amount of chitosan is 0.2 g, the additive amount of sodium alginate is 1.2 g, the additive amount of glycerinum is 1 mL and the additive amount of stearic acid is 0.2 g. The carboxymethyl potato residue edible packaging films are bright and uniform texture, exquisite and folding and can be used for food condiment and food powder edible green packaging.
