Title
(EN) FLEXIBLE SUBSTRATES WITH CHEMICAL AND MOISTURE RESISTANCE
(FR) SUBSTRATS SOUPLES À RÉSISTANCE CHIMIQUE ET À L'HUMIDITÉ
Abstract
(EN) Flexible packages, transdermal drug delivery devices, and methods for fabricating packages are provided. An exemplary flexible package includes a chemical and moisture resistant layer formed from poly (chlorotrifluoroethylene-co-vinylidene fluoride) ("P(CTFE-co-VDF)") copolymer. Further, the exemplary flexible package includes a substance to be delivered. The substance is applied to or enclosed by the chemical and moisture resistant layer.
(FR) L'invention concerne des emballages souples, des dispositifs d'administration transdermique de médicaments, et des procédés de fabrication d'emballages. Un emballage souple donné à titre d'exemple comprend une couche à résistance chimique et à l'humidité formée à partir d'un copolymère de poly(chlorotrifluoroéthylène-co-vinylidène) ("P (CTFE-co-VDF)"). En outre, l'emballage souple donné à titre d'exemple comprend une substance à distribuer. La substance est appliquée sur ou enfermée par la couche à résistance chimique et à l'humidité.
