POLYMER COMPOSITIONS AND OVENABLE TRAYS, TRAY BLANKS AND SHEETS FORMED THEREFROM

摘要

A crystallisable polymer composition comprises from about 70 - 95% PET, from about 4% to about 29% of a core/shell polymer, from about 1 to about 5% of an aromatic polyester crystallisation rate acceleration, and optionally upto 14.5% of an aromatic polycarbonate. The compositions may be used to form sheets, tray blanks and, particularly, ovenable trays.
