A biodegradable volatile corrosion inhibitor polyester composition, comprising:
- polyester comprising one or more biodegradable random copolymer polyesters and/or one or more biodegradable homopolymer polyesters;
- volatile corrosion inhibitors comprising:
- (i) sodium octanoate, (ii) one or more ammonium salts, and (iii) one or more of benzoic acid, sorbic acid, and a benzoic acid derivative;
- and
- at least one filler.
