What is a Blister Pack?
A
blister pack is formed of FORMING FILM and LIDDING MATERIAL formed
either side of the MEDICAMENT.
The
Forming Film is typically made of a thermoplastic material, such as
polyvinyl-chloride (PVC) or Polyvinylidene chloride-coated PVC
(PVDC).
The Lidding Material can be clear plastic, but in pharmaceutical packaging it is either plain or printed foil. Aluminium foil is most commonly the preferred material. The Lidding Material may also be made of a laminate of paper and foil with the foil upper surface being coated with a film of a thermoplastic material such as polyethylene or polystyrene.
Blister packs are opened, providing access to the medicament by deforming the Forming Film so that it punctures the Lidding Material and allows the Medicament to be removed therefrom, without applying directly a mechanical pressure to the medicament.
