RECYCLED PAPER AND BOARD AS A FOOD CONTACT PACKAGING

For the last two years I have focused my research interest on studying recycled paper and board as food contact materials. In STSM done within COST E46 action, titled Food Contact Analysis of Recycled and/or Deinked Pulp I studied food contact suitability of three different liner boards consisting of varying amounts of recycled matter. Aim of the work was to evaluate the suitability of different quality recycled paper packaging for direct food contact. The suitability was tested on the example of direct fatty foodstuffs application. All tested liner boards were compared with the quantitative restrictions laid down in the German BfR Recommendations, with which they have to stand in compliance. In another STSM titled Food Contact Analysis of Office Recovered Paper Grades, which was accomplished within COST E48 action, the possibility of using the office print-outs as an alternative furnish supply in the production of white top liner boards was evaluated. In that study different types of office print-outs were submitted to a chemical deinking flotation and laboratory made handsheets were tested for food contact suitability. As office paper grades usually contain high amounts of FWAs, the fastness of fluorescent whitened papers (bleed fastness) was determined.
