Abstract: Disclosed is a blend of a low density polyethylene (LDPE) and a specific multimodal metallocene catalysed linear low density polyethylene (mLLDPE), which provides films with well-balanced mechanical properties, especially dart drop (impact strength) and tensile modulus; i.e. high stiffness as well as high toughness, and additionally protrusion puncture resistance.
