Abstract
Article side polymers useful in the packaging of transdermal patches are disclosed. These films do not absorb skin permeation enhancers that are contained in transdermal patches including keto acids such as levulinic acid or sulfoxides such as an alkyl sulfoxide, e.g., dimethyl sulfoxide. Using such polymeric film, multilayer pouch constructions can be manufactured which include other polymeric layers, such as aluminum foil for moisture and oxygen barrier properties, polyester for tear resistance and paper layers for optimal printing and design.
