UV-blocking film for food storage using titanium dioxide

Abstract

We aimed to develop UV-blocking clear films for foods using the harmless titanium dioxide. The blocking rate for short-wavelength UV light (200 nm - 300 nm) was 99.2%, while that for long-wavelength UV light (300 nm - 400 nm) was 70.9%. The coating was transparent and adhered strongly to the films according to the JIS rule.
