Abstract:
A rigid thermally crystalline dual-ovenable food container made from a thermoplastic polymeric composition comprising:an alkylene terephthalate or naplithalate bulk polymer; an additive in a concentration from about 4 wt % to about 40 wt %, based on a total weight of the composition, comprising a substantially amorphous co-polymer of ethylene and an acrylate; and a compatibilizer/emulsifier/Surfactant (CBS) in a concentration from about 0.1 wt % to about 8 wt %, based on the total weight of the composition, comprising a grafted or backbone ter-polymer of ethylene and a glycidyl acrylate or maleic anhydride, and an acrylate selected from the group consisting of methylacrylate, ethylacrylate, propylacrylate, butylacrylate, ethylhexylacrylate, and mixtures thereof; wherein said container maintains dimensional stability at temperatures of about 250Â° F. and wherein said thermoplastic polymeric composition comprises reprocessed waste.
