1. A polymer blend for fabricating medical products comprising:

  • a first ethylene and α

    -olefin copolymer obtained using a single-site catalyst present in an amount by weight of from about 0% to about 99% by weight of the blend and having a melt flow index from about 0.1 g/10 min to about 5 g/10 min;

    a second ethylene and α

    -olefin copolymer obtained using a single-site catalyst and being present in an amount by weight of the blend from about 0% to about 99% and having a melt flow index from higher than about 5 g/10 min to about 20 g/10 min; and

    a third ethylene and α

    -olefin copolymer obtained using a single-site catalyst and being present in an amount by weight of the blend from about 0% to about 99% and having a melt flow index greater than about 20 g/10 min.
