Abstract

Thin Al2O3 coatings were deposited at low temperatures of 80 or 100°C on various polymercoated boards and plain polymer fi lms using the atomic layer deposition (ALD) technique. The work demonstrated that such ALD-grown Al2O3 coatings signifi cantly enhance the barrier performance against oxygen and water vapour. Even extremely thin (25 nm) barrier coatings of Al2O3 could be suitable barrier layers for dry food and pharmaceutical packages made from temperature-sensitive fi bre-based materials. It was also demonstrated that these coatings may have relatively high seal strengths when sealed against LDPE coatings or themselves. In addition, ALD-grown Al2O3 coating did not significantly reduce the degradability of biopolymercoated boards in composting conditions.
