Compostable bags are eco-friendly packaging solutions made from biodegradable materials like PLA (polylactic acid), PBAT, and starch-based compounds. Unlike traditional plastic bags, they break down into water, carbon dioxide, and organic matter under specific conditions, leaving no harmful residues behind.

The degradation time varies based on the material and environment. In industrial composting facilities, certified compostable bags (meeting EN13432 or ASTM D6400 standards) typically degrade within 3-6 months. In natural environments, the process may take longer, depending on factors like temperature, humidity, and microbial activity.

Certified biodegradable bags are plastic or polymer-based packaging products verified by authorized institutions to decompose naturally into water, CO₂, and organic matter under specific conditions (e.g., industrial composting). They are made from materials like PLA (corn starch-based) and PBAT (fossil-based but biodegradable)

Major certifications include:

EU Standards:
EN 13432: Requires ≥90% degradation within 6 months in industrial composting.
Labels: OK Compost (industrial), Seedling Logo (home composting).
US Standards:
ASTM D6400: Industrial composting guidelines, certified by BPI46.
USDA BioPreferred: Validates bio-based carbon content (e.g., via ASTM D6866).
China: GB/T 38082-2019: Mandates ≥60% biodegradation for single-component materials

Unopened: 2–3 years in dry, sealed conditions6.
Opened: Use within 6–12 months to avoid premature degradation

• Certification labels: OK Compost, BPI, or AS 4736 (Australia).
• Material tags: Look for “PLA+PBAT” or “PBS” on packaging.
• Price: Certified bags cost 2.5–3× more than regular plastic.
• Testing reports: Verify via third-party labs (e.g., SGS, OWS)

• Yes, but with caveats:

  They fully decompose only in certified composting facilities, not in landfills or oceans25.
  Avoid “oxo-degradable” plastics, which fragment into microplastics
