A Method of Reducing Volatile Compounds in Polypropylene Packaging Materials

Article Preview

Abstract:

When food contamination problems occur, one of the first priorities is adsorption to any volatile or semivolatile organic chemicals in packaging materials. In this contribution the adsorption behaviour of modified polypropylene composites containing nano-silica is reported. The nano silica can increase the polarity of PP and decrease more volatile solvent residue of ethyl acetate in CPP film. If lower volatile solvent used in print ink or adhesive, load of nano silica can decrease solvent residue too, when a lesser decrease is happen in crystallinity of modified PP. The nano modification process is able to produce more safe food packaging materials, but must consider the load of nanosilica.
