Abstract
The present invention relates to a polymer blend and the film of the polymer blend or the film layers of the polymer blend as a surface layer or coating. More particularly, the invention relates to a polymer blend which may be extruded as such or extruded onto one or both sides of packaging film to give a sealing surface(s) which exhibits surprisingly heat sealability suitable for form-fill-and-seal-packaging. The present invention also relates the use of ethylene based plastomer to reduce sealability of films comprising polypropylene.
