Abstract

The invention discloses a biodegradable preservative film material which contains polyhydroxyalkanoate. The invention also discloses a preservative film prepared by the material, wherein the preservative film has a proper penetration rate and a good oxygen blocking function, so that some fruits and vegetables can retain proper moisture but not be contact with oxygen to prolong the preservative time; and in addition, the biodegradable preservative film material has a good preservative effect, and can be completely biodegraded after the preservative film is discarded after use, and pollution to the environment is not caused.
