Abstract
Blends of non-solid stated RPET and an amount of PEN and/or NDC less than about 10 percent by weight are used as at least one layer of an article, such as a container or a preform for blow molding a container, having an inner layer of a thermoplastic material. The addition of the small amount of PEN and/or NDC allows the direct use of RPET without solid stating, and provides articles having environmental stretch crack resistance, color, and organoleptic properties comparable to that of virgin PET.
