Embodiments are directed to a stretch hood or stretch label multilayer film comprising a first skin layer, a second skin layer, and a core layer disposed between the first skin layer and the second skin layer, wherein: the first skin layer, the second skin layer, or both independently comprise at least 50 wt.% of a linear low density polyethylene (LLDPE) resin, wherein the skin LLDPE resin exhibits each of the following properties: a Crystallization Elution Fractionation (CEF) fraction of less than 8% above an elution temperature of 94°C; and a melt index (I 2 ) of 0.1 to 2.0 g/10 min when measured according to ASTM D 1238 at a load of 2.16 kg and temperature of 190°C. The core layer comprises a polyethylene resin having a wt.% crystallinity of from 10% to 40% and a single melting peak as measured by differential scanning calorimetry.
