Abstract
Atomic layer deposition (ALD), electron beam evaporation,
magnetron sputtering and a sol-gel method were
used to deposit thin aluminum oxide coatings onto two
different fiber-based packaging materials of
commercial board grades coated with synthetic and
biodegradable polymers. Significant decreases in both
the water vapor and oxygen permeation rates were
observed. With each technique the barrier performance
was improved. However, among the techniques tested ALD
was found to be most suitable. Our results
moreover revealed that biodegradable polylactic
acid-coated paperboard with a 25-nm thick layer of
aluminum oxide grown by ALD on top of it showed promising
barrier characteristics against water vapor and
oxygen.
