An extruded blow molded bottle comprises a neck portion and a body portion. The body portion comprises a first inner layer and a second layer. The first inner layer comprises a first material selected from a group consisting of polyester, phenoxy type thermoplastics, phenoxy-polyolefin thermoplastic blends, and combinations thereof. The second layer comprises a second material selected from a group consisting of virgin PET, recycled PET, PETG, foam, polypropylene, polyester, polyolefins, phenoxy type thermoplastic, phenoxy-polyolefin thermoplastic blends, regrind scrap materials, and combinations thereof. The second material is different from the first material.

The bottle of claim 1, wherein the third layer defines more than about 20% of the wall thickness of the body portion of the bottle. 15. The bottle of claim 1, wherein the third layer defines more than about 40% of the wall thickness of the body portion of the bottle. 16. The bottle of claim 1, wherein the third layer defines more than about 60% of the wall thickness of the body portion of the bottle. 17. The bottle of claim 1, wherein the bottle is made by blow molding an extruded profile. 18. The bottle of claim 1, wherein one or more of the first, second and third layers comprises a barrier material having a permeability to oxygen and carbon dioxide which is less than that of polyethylene terephthalate. 19. The bottle of claim 1, wherein one or more tie layers are positioned between two or more of the first, second and third layers. 20. A method of forming a bottle, comprising: forming regrind scrap material by regrinding discard material from an extrusion blow molding process, the discard material comprising a first material selected from a group consisting of phenoxy type thermoplastic, functionalized phenoxy type thermoplastic, phenoxy-polyolefin thermoplastic blends, functionalized phenoxy-polyolefin thermoplastic blends, and combinations thereof, and a second material selected from the group consisting of polypropylene, functionalized polypropylene, and combinations thereof;coextruding a profile having a first innermost layer, a second layer, and a third layer, the first innermost layer comprising the first material, the second layer comprising the second material, the second layer positioned exterior to the first innermost layer, and the third layer comprising the regrind scrap material, the third layer positioned exterior to the first innermost layer and interior to the second layer; andblow molding the profile to form a bottle.
