Migratie vanuit meerlaagse voedselverpakking met nieuwe nanocomposiet

29 oktober 2014

A novel clay/polymer composite film was prepared by applying a modified clay polymer suspension containing nanoparticles onto bi-axially oriented polypropylene films to form three-layer barrier film via lamination.
Among the aqueous food simulants tested, the 3% acetic acid solution demonstrated the highest migration levels, while the water was the least efficient migrating medium. Migration into fatty simulants was observed to be greater than those into aqueous solutions, but independent of their fatty acid composition. The results provided adequate guarantees for the developed film to be applied for food packaging materials (Food and Bioprocess Technology, 24 september 2014).
