China sets national standard for PHA biodegradable blown film

China's State Administration for Market Regulation has published a recommended national standard for polyhydroxyalkanoate (PHA) blown film used in commodity packaging, effective 1 April 2027. The standard defines technical requirements so converters and brand owners can verify film performance rather than relying on general biodegradability claims.

Why this mattersA defined performance standard lets Chinese converters and brand owners qualify PHA film against incumbent plastics on tested criteria rather than marketing claims.

  • China's State Administration for Market Regulation published two revised recommended national standards in the biodegradables field, including one for PHA blown film for commodity packaging
  • The PHA blown film standard takes effect on 1 April 2027
  • The standard gives material makers and packaging buyers specific technical criteria for film performance
