Abstract

The aim of the research was to analyse the dependence of storage conditions on the optical deterioration of coated wrapping paper. Three methods of common storage conditions were applied for a period of three years: preservation in the dark and dry place, storage in the common office conditions, and keeping in room conditions that enabled stronger influence of natural light and atmosphere pollutants. In order to examine optical modifications due to accelerated ageing, the same sample of paper was exposed to UV/VIS lamp radiation. Visible and IR spectroscopy were used for the characterization and comparison of paper degradation with the emphasis on the colour alterations as the crucial quality component. This research provides a solid basis for further development of non-invasive methods for investigating and predicting shelf life of coated wrapping paper.
