The objective of this research was evaluation of the suitability of recycled paper materials for direct food contact applications. Safety evaluation of various recycled paper grades was conducted in order to identify the contaminants that are present in certain types of recycled papers which have the ability to migrate into food and thus potentially endanger consumers’ health. Evaluation of the food contact suitability was conducted on selected classes of recycled papers that were produced either industrially or in laboratory conditions. Food contact analyses comprised determination of heavy metal contents (cadmium, lead and mercury), primary aromatic amines, diisopropylnaphthalene (DIPN), phthalates and polychlorinated biphenyls (PCB) from aqueous or organic solvent extracts of papers. First group of materials that were tested for the presence of contaminants comprised unprinted newsprint and magazine papers. Moreover, those two papers were mixed with equal proportions of dry fibrous matter and were subsequently disintegrated in a tap water without addition of any chemicals. Handsheets that were formed from the pulp thus obtained were tested for the presence of contaminants as well. Second group of materials comprised selected types of printed paper and boards that were treated in laboratory conditions by means of chemical deinking flotation. The deinked pulp handsheets formed after conducted deinking flotation were analyzed for the presence of contaminants as well. The conducted research showed that the most common contaminants present in the analysed papers were diisopropylnaphthalenes (DIPNs) and phthalates. Other evaluated contaminants, such as heavy metals (Cd, Pb and Hg), primary aromatic amines, polychlorinated biphenyls (PCBs) were found at extremely low concentrations.
