HiPERTUF(TM) polyester resins from Shell Chemical (Akron, OH) are homopolymer 2ƾ dimethyl naphthalate-based polyethylene naphthalate (PEN), which provide a number of benefits over PET, including hotter fill temperatures, better chemical resistance, and improved gas and UV barriers.
Green-Tek (Edgerton, WI) has developed dual-ovenable, micro-waveable and freezer compatible trays made of CPET. These thermally stable trays can withstand 40° to 400°F and are available in black or white.
