Matte biaxially oriented polypropylene film with improved matte property and processability |
摘要 |
Disclosed is a matte biaxially oriented polypropylene film having improved matte characteristic and processability. The film comprises one or more surface layers made of a composition comprising 100 parts by weight of a resin blend of 40-60 wt % of polyethylene (I) and 60-40 wt % of polypropylene (II), 0.005-0.04 parts by weight of a peroxide (III) and 0.1-0.5 parts by weight of a fluoroelastomer or a metal stearate (IV). The matte biaxially oriented film has low gloss (45°, <10%) and high haze (>70%), and solves problems related to increase of silver (or bright) spots and roughness of a matte pattern, and a shortened die cleaning cycle due to die build-up.
