  • Medium density polyethylene compositions for film applications
    Patent number: 6114456
    Abstract: Use of a homogeneous blend of a metallocene-catalyzed medium density polyethylene (mMDPE) with low density polyethylene (LDPE) and/or a linear low density polyethylene (LLDPE), to produce blown films, this composition essentially consisting of from 0.5 to 100% by weight of MMDPE and from 0 to 99.5% by weight of LDPE and/or LLDPE.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 mechanical and processing properties of MDPE.
