THERMOFORMED ARTICLE MADE FROM POLYBUTYLENE SUCCINATE (PBS) AND MODIFIED POLYBUTYLENE SUCCINATE (MPBS)

摘要

The present invention relates to articles made of a thermoformable resin comprising a biodegradable polymer having polybutylene succinate (PBS) via extrusion using an extruder which comprise: a biodegradable polymer having: (a) a Ts value of up to about 160°C (e.g., in the range of from about 50° to about 150°C); (b) a heat distortion index of up to about 150°C (for example, up to about 120°C); and (c) optionally, a Tm in the range of from about 70° to about 160°C (e.g., in the range of from about 80° to about 150°C). Thermo formed article such as a food or beverage cup, lid, cutlery item, foodservice item, molded tray, food storage container, etc provide the ability to resist deformation during higher temperature conditions that may occur during storage and distribution.
