Abstract
This work presents the first data on the performance of commercial polymers used in Modified Atmosphere Packaging (MAP) in Food Industry, to be used as support for TiO2 and provide them with photocatalytic properties. Optical properties of the plastics have been evaluated, and different operating conditions have been tested in order to optimize the fixation of the photocatalyst to obtain a homogeneous coating, with durable and high photocatalytic activity. The photocatalytic results obtained with these materials revealed good photocatalytic activity for elimination of trichloroethylene, which was tested as a model of volatile gas. Therefore, the methodology used in this work can be a valid method to obtain TiO2 thin films on plastic to be employed as “active packaging” and thus to decompose unwanted gases during the storage of vegetables and climacteric fruits.
