The present technology relates to a blown film comprising a multi-branched polypropylene having a g' of less than 1.00. In certain embodiments, the material properties of the film are represented by the equation <?in-line-formulae description="In-line Formulae" end="lead"?>SIT-0.03.EIM<=92;<?in-line-formulae description="In-line Formulae" end="tail"?> wherein SIT is the heat sealing initiation temperature of the film in ° C.; and EIM is the tensile modulus, in MPa, of at least one of the film in an injection-molded state measured according to ISO 527-2; and the polypropylene material in an injection-molded state measured according to ISO 527-2.
