Abstract
Depending on the carrier material, inorganic-organic hybrid polymers lower the oxygen- and water vapour permeabiltiy by the factor 500 and 3 respectively. By coating SiOx vapour-deposited films, both the oxygen- and also the water vapour high-barrier range is reached. With the use of ORMOCERES as barrier-laminating adhesives, the laminating composites show improved interlayer adhesion- and oxygen barrier properties compared with commercially available laminating adhesives. In combination with SiOx vapour-deposited films, one obtains transparent, high-barrier composites with excellent interlayer adhesion and stability vis-a-vis mechanical stress and sterilization.
