The present disclosure describes ethylene/α-olefin copolymer products with a density from 0.865 to 0.905 g/cm³ characterized as having unique rheological fingerprint during their transition from a solid state into a fully molten state. The ethylene/α-olefin copolymer products comprise a first high-density fraction and optionally a second high-density fraction. wherein said first and said optional second high-density fractions have distinct chemical compositions from that of the overall ethylene/α-olefin copolymer products. The first high-density fraction further has a weight-average molecular weight M_w,1^HD, wherein M_w,1^HD and the weight average molecular weight of the overall ethylene/α-olefin copolymer product M_w satisfy the inequality of M_w,1^HD/M_w>2.
