A food service item comprises a biodegradable polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure (i) wherein R1 is H or a C¿1-2? alkyl, and n is 1 or 2; and the second randomly repeating monomer unit has the structure (ii) wherein R?2¿ is a C¿3-19? alkyl or a C3-19 alkenyl. At least about 50 % of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit. |
