In this work, the mechanical, fracture, optical and transport properties of chemically surface modified polypropylene films were investigated. It was found that physical properties such as light transmittance, water permeation, and wettability were highly influenced by surface modification. On the other hand, the bulk mechanical and fracture properties resulted highly dependent on film orientation but independent of modification.
