Abstract:
Disclosed are multilayer structures comprising a polyolefin layer, a tie layer and a barrier layer wherein the tie layer is a formulation comprising a crystalline block copolymer composite (CBC) comprising i) an ethylene polymer (EP) comprising at least 90 mol % polymerized ethylene; ii) an alpha-olefin-based crystalline polymer (CAOP) and iii) a block copolymer comprising (a) an ethylene polymer block comprising at least 90 mol % polymerized ethylene and (b) a crystalline alpha-olefin block (CAOB).
