Definitions

  • PLA has a problem in that biodegradation occurs slowly in a daily environment because biodegradation proceeds under certain conditions of 60 ° C. or higher and 70% or higher moisture.
  • the present invention is formed of a sheath part and a core part, and the biodegradability of PLA can be further improved by including low melting point PLA and PHA in the sheath part and using PLA and PHA together in the core part.
