Title
Verbundsystem mit Sauerstoff-Scavenger/Indikator-Funktion und dessen Verwendung
Other Title
Composite system, useful e.g. for protecting oxygen-sensitive components in electronic or electrical devices, comprises a substrate foil and at least one scavenger-/indicator layer containing a metal as oxygen sorbent
Abstract
Die Erfindung betrifft ein Verbundsystem mit der Funktion als Scavenger/Indikator fuer Sauerstoff, der mindestens ein Metall als Sauerstoff-Sorbens enthaelt, das durch Sauerstoff in eine hoehere Oxidationsstufe ueberfuehrbar ist. Darueber ist weiterhin ein Aktivator enthalten. Die Indikatorwirkung wird durch eine Aenderung der physikalischen Eigenschaften des Sauerstoff-Sorbens bewirkt, die durch die Oxidation des Metalls bewirkt wird.

DE 102005055635 A1 UPAB: 20071024 NOVELTY - Composite system comprises a substrate foil and at least one scavenger-/indicator layer, which is separated in the vacuum as a thin film, contains at least a metal as oxygen sorbent, where the sorption of oxygen changes at least a physical characteristic of the oxygen sorbent, and at least a stationary activator, which is in direct contact to the scavenger layer, for the oxidation of oxygen sorbent. USE - The composite system is useful as packaging foils or partially decorated single foil and for the protection of oxygen-sensitive components in electronic or electrical devices (claimed). ADVANTAGE - The composite system as oxygen-scavanger-/indicator system can visually or measurably signal the remainder capacity of the oxygen-scavanger and the excess of oxygen concentration span.
