Abstract
The present invention relates to a polymer composition (A) comprising a blend of i) 60 to 90 wt-% of propylene polymer composition (a) comprising a blend of (a-1) 55 to 95 wt-% of propylene polymer and (a-2) 5 to 45 wt-% of low density ethylene polymer and ii) 10 to 40 wt-% of a plastomer (b) of ethylene copolymer. The invention relates also to extrusion coating articles, comprising at least a substrate layer and a heat sealable layer, wherein composition (A) is used as said heat sealable layer, process for producing the extrusion coated articles as well use of the composition (A) as a heat sealable layer in an extrusion coated article.
