EXTRUSION COATING PROCESS OF HIGH DENSITY POLYETHYLENE

摘要

The invention discloses an extrusion coating process of a polyethylene resin on a substrate characterised in that the polyethylene resin having a density of from 0.940 g/cm<SUP>3</SUP> to 0.960 g/cm<SUP>3</SUP> is prepared in the presence of an activated bridged bis (tetrahydro-indenyl) metallocene catalyst. The resin may be used alone or in combination with LDPE. The invention also covers the coating obtainable by the process and its uses.
