Abstract
AbstractThermoformed fossil‐based disposable packaging is widely used in everyday life but it represents a serious environmental problem, as it is often incorrectly dispersed or destined to landfills. Bio‐based and biodegradable materials can constitute and effective solution to this issue. Two different blends of poly(butylene succinate‐co‐butylene adipate) (PBSA) and Poly (3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHBH) were studied as constituents for disposable packaging production. The blends were produced via twin screw extrusion. Sheets were cast extruded and then thermoformed into trays. A rheological, thermal and mechanical characterization was performed on compounds and manufacts. Both blends presented a good processability and interesting properties for packaging application, which can be tailored by varying the percentage of constituent polymers.
