Research on Migration of Lead in Food Wrap Paper

Abstract:

Along with the widespread use of food wrap paper, it is very important to discuss the migration of lead in paper. The migration of lead from six kinds of food wrap papers under different temperatures (5 °C, 25°C, 35°C, 60°C and 85°C) were investigated by using water as an imitation in this paper. It was found that the initial migration rate was affected by the sizing degree of paper, but the final migration ratio was mainly decided by initial concentration of lead in paper, and the migration rate increased with the increasing of temperature.
