The Effect of Nano-Modification on Performance of Cast Polypropylene Film
Nanomaterials have been demonstrated to possess novel characteristics that can be applied in developing new packaging with better properties than packaging produced with ordinary micromolecules materials. Such developments include the production of packaging with improved mechanical or barrier properties, which applied to the food industry will extend the shelf life of a food, thereby expanding its marketing potential. The present study discussed on approaches to reduce low molecular weight chemicals residue in flaxible films via modification by nano-SiO2. The results of the study showed that the cast-polypropylene films with nano- SiO2 particles have good adhesiveness of ink and peeling strength, especially low adsorption behavior of solvents in inks or adhesives, and low friction coefficient in absence of any slip agents.
