A four-layer film for packaging, including blister packaging, is described. Layermay be a rigid film, such as a polyvinyl chloride (PVC) or polyester. Layermay be a moisture barrier, such as polychlorotrifluoroethylene (PCTFE). Layermay be an oxygen barrier, such as a co-extruded film having a polyethylene (PE) layer, an EVOH layer, and a second PE layer. Layermay be a relatively thin layer of a rigid film, such as a PVC or polyester. In this arrangement, Layermay protect the contents of the package from external or atmospheric moisture. Layermay also protect Layerfrom atmospheric moisture, thereby helping to preserve the effectiveness of Layeras an oxygen barrier.
