ABSTRACT:
A method of making a polyethylene terephthalate/polyolefin blend for sheeting and thermoformed articles which has improved color stability and can be recycled many times. A heat stabilizer is melt blended only with the polyolefin prior to its incorporation into the polyethylene terephthalate. The PET and polyolefin are then blended and extruded into sheeting and subsequently thermoformed into articles useful as microwave oven trays.
