Matte surface film with improved matte appearance

摘要

The present invention relates to a matte surface film comprising: a base layer comprising a polyolefin; and a matte surface layer comprising a blend of high molecular weight high density polyethylene (HMWHD PE) with at least one incompatible polyolefin. The incompatible polyolefin may be ethylene propylene (EP) copolymers, ethylene butylene propylene (EBP) terpolymers or polypropylene (PP) homopolymers, such as metallocene catalyzed isotactic polypropylene (m-iPP) or metallocene catalyzed syndiotatic polypropylene (m-sPP). The matte surface layer may additionally contain a low molecular weight high density polyethylene or a medium molecular weight high density polyethylene. The film possesses an improved matte appearance and may be used for packaging and label applications.
