Benefits of technology

[0044] In another embodiment, a method of producing a bottle comprises extruding a profile comprising a first layer and a second layer. The first layer comprises a first material selected from the group consisting of virgin PET, recycled PET, PETG, foam, polypropylene, polyester, polyolefins, phenoxy type thermoplastic, phenoxy-polyolefin thermoplastic blends, nanocomposites, regrind materials, and combinations thereof. The second layer comprises a second material selected from the group consisting of virgin PET, recycled PET, PETG, foam, polypropylene, polyester, polyolefins, phenoxy type thermoplastic, phenoxy-polyolefin thermoplastic blends, nanocomposites, regrind materials, and combinations thereof. The second materi

Problems solved by technology

The PET bottle may not provide a suitable thermal barrier for limiting thermal communication through the walls of the PET bottles.
Similarly, most inexpensive containers for holding foodstuffs do not provide an effective thermal barrier to reduce heat transfer through the container.
Additionally, articles in the form of conduits, food packaging, a
