1. A batch inclusion package which comprises(A) an ingredient used to make an article packaged in(B) a protective film comprising at least one layer of at least one substantially linear ethylene/C3 -C20 α

  • -olefin polymer, wherein the protective film (B) becomes part of the final article comprising the ingredient and wherein the substantially linear ethylene/α

    -olefin polymer is characterized as having;

    a) a melt flow ratio, I10 /I2, ≧

    5.63,b) a molecular weight distribution, Mw /Mn, defined by the equation;

    Mw /Mn

    (I10 /I2)-4.63,c) a critical shear rate at onset of surface melt fracture of at least 50 percent greater than the critical shear rate at the onset of surface melt fracture of a linear ethylene/α

    -olefin polymer having about the same I2 and Mw /Mn, andd) a density from about 0.87 g/cm3 to 0.92 g/cm3.
