Coated substrates include a coating and a substrate is selected from the group consisting of paper, fabric, thread and yarn. The coating comprises a biodegradable polyhydroxyalkanoate copolymer, wherein the biodegradable polyhydroxyalkanoate copolymer comprises a first randomly repeating monomer unit having the structure: n n n wherein n R 1 is H or a C 1-2 alkyl, and n is 1 or 2; and n a second randomly repeating monomer unit having the structure: n n n wherein n R 2 is a C 3-19 alkyl or a C 3-19 alkenyl; and n wherein at least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit. |
