Kinetic migration studies using Porapak as solid-food simulant to assess the safety of paper and board as food-packaging materials.
Porapak has been studied as a solid-food simulant in experiments on paper and board packaging. Three samples of paper with different recycled pulp content and surface treatment, and of different grammage and thickness, were used for the studies. Kinetic behaviour from 25 degrees C to 100 degrees C and different contact times ranging from 5 min at 100 degrees C to 10 days at 25 degrees C were studied using Porapak or, occasionally, Tenax or milk powder. Similar results were obtained with Porapak and Tenax but those from Porapak were more stable with temperature. Porapak behaves as good solid-food simulant even at high temperature.
