The invention discloses a process for making a film having a substantially uniform distribution of components and a desired level of an active component, comprising the steps of (a) combining a polymer component, polar solvent and an active component, such as herein described, to form a matrix with a uniform distribution of said components; (b) forming a film from said matrix; (c) providing a surface having top and bottom sides; (d) feeding said film onto said top side of said surface; and (e) drying said film by applying heat to said bottom side of said surface and exposing said film to a temperature above a degradation temperature of said active component, wherein said active component is maintained at said desired level.
