Roll-to-Roll Atomic Layer Deposition for Flexible Substrates

摘要

1. Functional structures with roll-to-roll ALD deposited barrier layers are possible for paper and paperboard based materials. 2. It is important to avoid contamination of the substrate prior to the ALD deposition process. 3. As the ALD coatings are sensitive to mechanical stresses, it is important to remember careful web handling. 4. Lamination of the ALD layer underneath a sealing layer is recommended to protect the barrier layer quality.
