A polymer composition comprising:

• at least one multimodal ethylene-based polymer having a density from 0.900 to 0.940 g/cc when measured according to ASTM D792 and a melt index (I2) from 0.1 to 10 g/10 min when measured according to ASTM D1238 at a load of 2.16 kg and temperature of 190° C., the multimodal ethylene-based polymer comprising a first ethylene-based component, a second ethylene-based component, and a third ethylene-based component, wherein each of the first ethylene-based component, the second ethylene-based component, and the third ethylene-based component are polymerized reaction products of ethylene monomer and at least one C3-C12 α-olefin comonomer, wherein;
• the first ethylene-based component has a density of 0.860 to 0.915 g/cc, and a weight-average molecular weight (Mw(GPC)) of 128,000 g/mol to 363,000 g/mol, the multimodal ethylene-based polymer comprising at least 20% by weight of the first ethylene-based component;
