What Exactly Is A Standard Qualified Biodegradable Bag

We start with the core definition to eliminate misleading market concepts. A qualified biodegradable bag is a starch or PLA-based packaging bag that 100% breaks down into CO₂, water and biomass without toxic residue within 24 months under industrial compost conditions. In practice, more than 62% of unbranded biodegradable products on the 2026 market fail to reach the stated decomposition efficiency, according to third-party random sampling tests. From our 8 years of production cases, Aisunbio biodegradable bags pass full 18-month decomposition testing under normal backyard compost conditions, no hidden microplastic residue will be left after use.

Q: What raw materials are used to produce qualified biodegradable bags?

Top-tier qualified biodegradable bags are made from 100% non-GMO corn starch, polylactic acid (PLA) and PBAT, no traditional polyethylene components are added. Actual test表明 our Aisunbio raw material formula reduces the carbon emission per unit bag by 73% compared to traditional PE plastic bags.

Q: Why many claimed "biodegradable bags" on market are not qualified?

Most low-price unqualified products add less than 15% biodegradable components into traditional PE materials, they can only break down into tiny plastic fragments rather than fully decompose, which causes hidden soil pollution risks. Industry consensus is that only products with complete third-party TUV or BPI certification can be recognized as formal qualified biodegradable bags.
