Oxygen barrier and mechanical properties of masterbatch-based PA6/nanoclay composite films

“

This study focuses on the possibility of improving performance properties of polyamide-6 (PA6) nanocomposite films for packaging application using nanoclay masterbatch. Different concentrations of nanoclay in PA6 were prepared through melt-mixing of particulate nanoclay and nanoclay masterbatches in a twin screw compounder, then film samples were molded using a hot press. Oxygen barrier properties were then measured and interpreted on the basis of different theoretical approaches. Also, a correlation between morphology and properties of the studied nanocomposites was observed.
