Abstract

A new type of degradable composite packaging film, limonene-corn starch composite film, was prepared by casting film forming method using corn starch, limonene and glycerin. The comprehensive properties of the composite membrane were analyzed by testing its mechanical properties, water vapor transmission rate, water absorption rate and the like. Results: compared with the pure corn starch film, the addition of limonene reduces the light transmittance of the composite film, and the mechanical properties and moisture barrier properties are improved, especially the elongation at break of the composite film is greatly improved. With the addittion of corn starch of 20 g, glycerin added of 6 g, and limonene of 1.6 g, the elongation at break was the highest of 42.92%, and the tensile strength was the highest of 15.02 MPa. The composite packaging film is expected to be useful as a novel food packaging material.
