  • Biaxially oriented matte polypropylene film
    Patent number: 9745455
    Abstract: 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. The multi-layer BOPP film has additional layers such as a second polyolefin resin-containing layer, a metal layer, or combinations thereof.
    Type: Grant

  • BIAXIALLY ORIENTED POLYPROPYLENE FILM WITH IMPROVED MOISTURE BARRIER
    Publication number: 20130295395
    Abstract: Embodiments herein relate to a biaxially oriented film comprising a core layer (B) comprising a blend of a high density polyethylene and a crystalline polypropylene, wherein the biaxially oriented film has a lower moisture vapor transmission rate than that of a biaxially oriented polypropylene (BOPP) film have a same structure and composition as that the biaxially oriented film except the BOPP film has the core layer (B) containing 100 wt % of the crystalline polypropylene.
