1. A method for manufacturing an implantable film including an upper film layer, an intermediate film layer, and a lower film layer, the method comprising:
forming the intermediate film layer by:
combining poly(lactide-co-glycolide) (PLGA), a releasing agent, and an active agent in a solvent, and
evaporating the solvent to form the intermediate film layer, wherein the active agent constitutes from 40 wt % to 80 wt % of the intermediate film layer;

forming the upper film layer on an upper surface of the intermediate film layer by dip coating, wherein the upper film layer includes PLGA and is configured to control release of the active agent from the intermediate film layer; and
forming the lower film layer on a lower surface of the intermediate film layer by dip coating, wherein the lower film layer includes PLGA and is configured to control release of the active agent from the intermediate film layer.
