Migration potential of nanosilver from LDPE food packaging

An experimental nanosilver coated low density polyethylene (LDPE) food packaging was incubated with food simulants using a conventional oven and tested for migration according to Commission Regulation (EU) No. 10/2011. The commercial LDPE films were coated using a layer-by-layer (LbL) technique.
An important finding was the significant reduction in migration resulting from the increased Ag precursor concentration used to attach Ag on the LDPE LbL coated films. This observation merits further investigation into the LbL coating process used, as it suggests potential for process modifications to reduce migration (Food Additives & Contaminants: Part A, 2 November 2015).
