Abstract: The invention discloses a preparation method of highly transparent self-adhesive PBAT cling film. The raw materials include PBAT, ACR, glycerin, and glycerin fatty acid ester; the preparation methods include mixing, preparing pellets, film blowing, and film winding. In the invention, ACR is added into PBAT resin, which increases the ductility, shrinkage property and flatness of winding of PBAT cling films; glycerin can improve the extrusion stability, softness and adhesion properties of PBAT cling films; glycerin fatty acid ester can improve the anti-fog property of PBAT cling films; meanwhile, glycerin and glycerin fatty acid can play a synergistic role to further enhance the anti-fog property of PBAT cling films. The PBAT cling film prepared by the invention has superior physical property, high transparency, high adhesion property, high shrinkage property, smooth flatness of winding free of wrinkles and good air permeability.
