Abstract:
A comprehensive study has been conducted to evaluate the feasibility of replacing multimaterial structures containing Biaxially Oriented Polypropylene (BOPP) or Biaxially Oriented Polyethylene Terephthalate (BOPET) with monomaterial structures of Polyethylene (PE) using Machine Direction Orientation (MDO) post-extrusion technology. This report presents the design of a MDO PE film that exhibits heat resistance, high stiffness, good optical properties, and near-easy tearing in both machine and cross directions. The study meticulously examined all process parameters of the MDO, gaining a thorough understanding of their impact on the desired properties. The findings of this study demonstrate the viability of substituting BOPP and BOPET films with MDO PE films, offering significant advancements in film performance and sustainability.
