Impact of UV cured inks and UV Exposure on Physical Properties of BOPP Films

摘要

Biaxially oriented Poly (propylene) [BOPP] films are extensively used in food packaging industry primarily because of their good barrier properties, machinability and printability. We investigated the effect of flexographic UV-cured acrylic inks on to BOPP films with a focus on permeability towards oxygen and moisture. Temperature dependence on mechanical properties of the printed films was studied. Instron tensile strength, Mocon permeability tests, and thermodynamic results were obtained that suggest that there is no appreciable change in the physical properties when the films are printed with UV curing inks.
