A multi-layer biaxially oriented polypropylene (BOPP) film with a novel formulation which exhibits matte appearance is disclosed. This improved formulation comprises a blend of high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE) or linear low density polyethylene (LLDPE) with polypropylene (PP) used in the core layer to achieve a matte appearance low gloss PP-based film that still exhibits typical properties of BOPP films with significantly lower haze than conventional matte films.
