Packaging Properties of Composite Film Made up of Polylactic Acid (PLA) and Triacetin
Triacetin (TAC) was used as plasticizer to improve the ductile of polylactic acid (PLA). A composite film composed of PLA and TCA was therefore Paraed, and the packaging properties of this film were tested including the elongation, tensile strength, tear strength, Transparency and permeability. The results suggest that the film owns superior synthetically packaging properties when the proportion of TAC is 30 % (mass ratio). At the same time, this film has a low gas barrier which is especially for the package of the novel vegetable and fruits.
