Abstract
Use of a homogeneous blend of a metallocene-catalysed medium density polyethylene (mMDPE) with low density polyethylene (LDPE), to produce blown films, this composition essentially consisting of from 0.5 to 99.5 % by weight of mMDPE and from 99.5 to 0.5 % by weight of LDPE, based on the total weight of the blend. The blend is optionally coextruded between layers of LDPE. The compositions of this invention have good processability and are used to make blown films which have the good optical properties of LDPE and the good mechancial and processing properties of MDPE.
