A bimodal ethylene-co-1-butene copolymer consisting essentially of a higher molecular weight component and a lower molecular weight component and, when in melted form at 190 degrees Celsius, is characterized by a unique melt property space defined by a combination of high-load melt index, melt flow ratio, and melt elasticity properties. A (blown) film consisting essentially of the bimodal ethylene-co-1-butene copolymer and having improved properties. Methods of synthesizing the bimodal ethylene-co-1-butene copolymer and making the blown film. A manufactured article comprising the bimodal ethylene-co-1- butene copolymer.
