摘要： A film includes 20.0 weight percent to 69.5 weight percent of a linear low density polyethylene (LLDPE) based polymer. The LLDPE having a high density fraction (HDF) from 3.0% to 8.0%, an I10/I2 ratio from 5.5 to 6.9, and a short chain branching distribution (SCBD) of less than or equal to 8.0° C. The film also includes 0.0 weight percent to 10.0 weight percent low density polyethylene (LDPE) based polymer, and 30.0 weight percent to 70.0 weight percent pore former.
