Influence of Nano-Silica on Solvent Absorption in Polypropylene Packaging
In this paper, the influence of nano-silica on adsorption behavior of solvent in polypropylene packaging is reported. A principle of reducing solvent residue in polypropylene packaging was explored through analyses of changes of crystallization behavior, polarity, and solubility parameters of nano-silica /polypropylene composites. The results showed that the value of solvent residue in modified polypropylene films was reduced about 50%. Therefore nano-silica modified polypropylene films with lower solvent adsorption are in accordance with food safety.
