The invention discloses an application of hyperbranched polyester to plastic processing, and belongs to the technical field of plastic processing assistants. The application of the hyperbranched polyester to plastic processing includes the steps that by mass, 0.1% to 5% of the hydroxyl-terminated hyperbranched polyester is added into plastic; the mixture is mixed to be even, extruded, prilled and dried, and a modified plastic product is obtained. According to the application, the plastic such as PPC and the hyperbranched polyester are melted and blended, and the plastic such PPC is modified through a double-screw extruder; after the hyperbranched polyester is added into a base material of the plastic such as PPC, the effective melt viscosity of the plastic such as PPC can be remarkably reduced; in other words, processing temperature and thermal degradation are reduced; in addition, melting fluidity improved in this way can also be achieved through the small adding amount,, and extruding film forming can be more easily achieved; the tensile strength of the modified plastic such as PPC is up to 30 MPa, and the strength can be higher than the strength of thin-film-level LLDPE and the strength of thin-film-level PVC.
