China revises national standard for PHA blown film used in packaging

China's State Administration for Market Regulation has published a revised recommended national standard for biopolyester polyhydroxyalkanoate (PHA) blown film, covering film for commodity packaging, which takes effect on 1 April 2027. According to the report, the standard gives film producers and packaging buyers a more specific technical basis and prompts companies to distinguish material biodegradability from a finished pack's performance in use.

Why this mattersA defined performance standard gives converters and brand owners a common technical basis to qualify PHA film, a precondition for scaling biodegradable packaging beyond pilot use.

  • The revised recommended national standard is titled Biopolyester Polyhydroxyalkanoate (PHA) Blown Film
  • It is one of two revised biodegradable-material standards published by the State Administration for Market Regulation
  • The standard takes effect on 1 April 2027
  • It covers blown film used for commodity packaging

Updates

  • 2026-10-28 · Edited before publication: The source calls it a new edition (revised) of the standard, not a new standard. The source does not say the standard sets thickness, mechanical or sealing requirements; that was the article's commentary. Removed, along with the Tianyancha company counts, which the source says do not reflect PHA capacity.
  • 2026-10-28 · Edited before publication: The point about distinguishing material biodegradability from performance in use is the article's comment, not a provision of the standard. I now attribute it to the report.
