Abstract
The invention discloses a flexible multilayer packaging material for protecting articles that are sensitive to moisture and oxidizing agents. The packaging material has at least one active polymeric barrier layer that is able to bind the moisture and oxidizing agents and at least one ceramic barrier layer. The combination of the active polymeric barrier layer and the ceramic barrier layer significantly enhances the barrier abilities of the multilayer packaging material.
