Blister packs perfectly protect each individual tablet or capsule and are considered as the best packaging for pharmaceuticals, in terms of safety, traceability, hygiene and product life. Solvay and SolVin PVC grades as well as dedicated Diofan® PVDC dispersions are preferred raw materials for key blister film manufacturers. They offer PVC mono films and advanced PVC/Diofan® PVDC or PVC/PE/Diofan® PVDC multilayer films, which are particularly suitable as reliable secure packaging solutions for drugs that are sensitive to moisture.

In general, those films are thermoformed, filled and sealed with an aluminum foil lidstock by the pharmaceutical companies themselves.

“The strategy of using calendar blister packs could help large numbers of patients (including seniors, children, and those challenged by cognitive, physical, or functional impairment) take their medication more reliably and safely, and enhance their treatment outcomes.”
