Materials intended for contact with food must not transfer any constituents to the food that
might endanger human health, change the composition of the food, or cause a deterioration in
its organoleptic properties. These stipulations contained in Council Directive 89/109/EEC
issued by European Commission conce all materials and articles coming into contact with
food. In the case of paper and board materials, however, little research is being carried out to
determine whether these stipulations are fulfilled. The purpose of this study was to determine
what potentially hazardous substances are present in paper and board packaging materials and
whether these can migrate into food itself.
More specifically, the aims were:
- to develop methods for testing barriers in food packaging materials (II)
- to investigate what potentially hazardous substances are present in paper and board
packaging materials (I, III-V)
- to develop methods using a solid food simulant (Tenax) for testing migration from fiberbased
materials (III, V)
- to compare the results of migration tests using Tenax with migration into foods (III, IV)
- to develop the simplest experimentally verifiable model for migration through a fiber
network (VI)
