Abstract: A method for preparing a polyester modified material from a recycled release film includes continuously performing the following steps at an elevated temperature: subjecting the recycled release film to a first melting treatment to form a low-viscosity polyester; subjecting the low-viscosity polyester to a polymerization treatment to form a high-viscosity polyester, wherein a viscosity of the high-viscosity polyester is greater than a viscosity of the low-viscosity polyester; and adding a modifier to the high-viscosity polyester to perform a second melting treatment to form the polyester modified material.
