    High concentrations of aroma compounds can affect packaging materials. The goal of this work was to study aroma compounds in a set of products, sorption of these compounds into model packaging materials, and the effect of such sorption on the materials. The effect of both indirect and direct contact with lemon tea, white pepper and clove on four different materials was tested. These simple test methods can help to predict which aroma compounds might potentially cause changes in the barrier properties. Different compounds and amounts of compounds were transferred into the packaging materials in indirect and direct contact with the products. While the tested products had only a slight effect on the water vapour permeability of, for example, polyethylene and polypropylene coated substrates, all the products impaired the water vapor barrier of dispersion coated board and some also the gas barrier. In addition, the most aggressive product - clove - caused visible changes in the surface properties of one of the materials.
