Thin (25 nm) and highly uniform Al2O3 coatings have been deposited at relatively low temperature of 80 and 100 °C onto various bio-based polymeric materials employing the atomic layer deposition (ALD) technique. The work demonstrates that the ALD-grown Al2O3 coating significantly enhances the oxygen and water vapor barrier performance of these materials. Promising barrier properties were revealed for polylactide-coated board, hemicellulose-coated board as well as various biopolymer (polylactide, pectin and nano-fibrillated cellulose) films.
► Al2O3 coatings (25 nm) were deposited at 80 and 100 °C.
► The atomic layer deposition (ALD) technique was used.
► The coating efficiently enhanced the barrier properties.
► Substrates were all bio-based.
► Coatings meet the requirements for food packages.
