Abstract:
Papers used for food packing were studied for formaldehyde migration from them by the colorimetric method with acetylacetone. The studied material comprised 14 samples of paper of Polish or foreign production: pergamenous paper, offset and sulphite papers and one sample from waste paper imported from Germany. Formaldehyde migration from these samples differed but never exceeded 1 mg/dm2, with the exception of the recycled paper from which it was 1.77 mg/dm2.
