Films derived from an ethylene -±-olefin copolymers prepared in a particle forming polymerisation process in the presence of a single site catalyst system are characterised in having < 600 gels/m 2 of size in the range 100 - 2000 µm as measured by an optical control system (OCS). The low level of gels produced with the inventive catalyst is particularly significant with respect to the use of the polymers in for example highly demanding blown film applications. |
