Claim Text:
1. A multilayered structure, comprising: at least one A layer (a2) comprising at least one polyolefin; one A layer (a1) comprising at least one polyolefin; at least one B layer (b1) comprising at least one of a cyclic olefin copolymer and a cyclic olefin polymer; one A layer (c1) comprising at least one polyolefin; and at least one A layer (c2) comprising at least one polyolefin; wherein the multilayered structure is flexible and at least partially transparent, layer (a2) is fully in contact with layer (a1), layer (a1) is fully in contact with layer (b1), layer (b1) is fully in contact with layer (c1), and layer (c1) is fully in contact with layer (c2), and wherein the multilayered structure is free of tie layers between A layers and B layers; wherein the multilayered structure has an average wall stress or hoop stress at failure that is higher than the average wall stress or hoop stress at failure of a corresponding multilayered structure having a poly(hexamethylene adipamide-co-caprolactam) layer in place of each of the B layers and having an anhydride-modified LLDPE tie layer in place of each of the at least one A layer (a1) and the at least one A layer (c1); wherein the cyclic olefin copolymer or polymer of the B layer (b1) is independently a copolymer or polymer of a cyclic olefin having the structure (I) wherein R
