Title: (EN) TRANSPARENT BARRIER LAMINATES
Abstract: front page image
(EN)

A novel, transparent, non-substrate-based permeation barrier film for encapsulating electronic, more particularly optoelectronic, assemblies consists of a first polymer layer (10), a first inorganic barrier layer (20), at least one at least partially organic compensation layer (30), at least one further inorganic barrier layer (21) and also at least one further polymer layer (11), wherein the polymer layers and the inorganic barrier layers, respectively, can be made of the same or different material, wherein the inorganic barrier layers have a thickness of between 2 and 1000 nm, and wherein the polymer layers and the at least partially organic compensation layer have a thickness of less than 5 [mu]m, preferably between 0.5 and 4 [mu]m. The film can have, on one or both sides, an auxiliary carrier attached by means of a re-releasable adhesive. It is also possible for a plurality of films to be laminated to one another by means of a further at least partially organic compensation layer.
