This work proposes the surface chemical modification of polypropylene films (PP) by Atom Transfer Radical Polymerization (ATRP) using glycidyl methacrylate (GMA) as the graft monomer. At a later stage, the epoxy groups of PP-g-PGMA were used for covalent binding of Glucose Oxidase (GOD) to obtain an active material (PP-g-PGMA-GOD) with 9.38 ± 0.02 mg.cm-2 of enzyme bonded on the surface of PP. The preliminary antimicrobial studies have demonstrated that this methodology of covalently bonding of the enzyme allow to maintain its activity giving to PP-g-PGMA-GOD potential use as antimicrobial active packaging film applications.
