A dermal or transdermal therapeutic system comprising a sheet-like substrate or reservoir containing readily volatile auxiliary agents or active agents, which substrate or reservoir is covered on one of its sides with a backing layer impermeable to the ingredients and on the opposite side with a detachable, likewise impermeable protective layer to prevent loss of ingredients during prolonged storage, is characterized in that both the backing layer and the protective layer are made of plastic film which is impermeably coated on both sides with vapour-deposited metal.
Système thérapeutique dermique ou transdermique qui comprend un substrat ou réservoir plan contenant des substances actives ou auxiliaires légèrement volatiles. Ledit substrat est couvert sur l'une de ses faces d'une couche arrière imperméable à ces substances et sur sa face opposée d'une couche de protection séparable, également imperméable, destinée à empêcher la perte des substances actives ou auxiliaires en cas de stockage à long terme. Ledit système est caractérisé en ce que tant la couche arrière que la couche de protection sont constituées par une feuille de plastique dont les deux faces ont été métallisées sous vide pour rendre ladite feuille imperméable.
