 Abstract
For testing the ultraviolet (UV)-blocking property of functional films coated with Nano- particles, UV-Vis spectra of oriented polypropylene (OPP) films uncoated and coated with of 3% and 5% in Polyurethane (PU) and polyvinyl butyral (PVB)-Cellulose binders were measured. The result of UV-Vis analyses showed that the film coated with 5% in PVB binders had a significant effect on UV protection of 90% compared with the film uncoated. Also The result of The photodegradation of methylene blue (MB), OPP films coated with 5% in both PU and PVB binders had a high photocatalytic activity for MB degradation. To evaluate the effect of the developed functional film coated with Nano- particles, fresh soybean sprouts were used. Nano- coated film was observed to decompose the off-flavor produced by soybean sprouts within packages during distribution, but uncoated film did not. Therefore, Nano- coated film package could give the greatest effect in extending the shelf life of soybean sprouts.
