As the world shifts toward a greener future, Chinese manufacturers are stepping up to meet the growing demand for eco-friendly, certified compostable packaging.
With its strong supply chain and competitive pricing, China is a key destination for sourcing compostable bags that meet international standards such as EN 13432 and ASTM D6400.
In this article, we list the top 5 trusted Chinese wholesalers and offer tips on how to choose the right supplier.
What Are Compostable Bags?
Compostable bags are made from plant-based, biodegradable materials such as PLA, PBAT, and cornstarch blends.
Under industrial or home composting conditions, they break down into CO₂, water, and biomass within 3–6 months, leaving no toxic residue behind.
Why Choose Compostable Bags?
- ✅ Reduce plastic pollution by diverting organic waste from landfills
- ✅ Support a circular economy: waste → compost → healthy soil
- ✅ Enhance your brand with a sustainability-first image

FAQ
Q1: What’s the difference between industrial and home compostable bags?
Industrial bags need 55–60 °C and high humidity; home-compostable bags degrade at lower temps over a longer period.
Q2: Can these bags be recycled instead of composted?
No—compostable bags should go into organics/compost streams. Mixing them into plastics recycling can contaminate that stream.
Q3: How do I verify a supplier’s certifications?
Ask for downloadable certificate PDFs or scan-code links for BPI/OK Compost/EN 13432 registries.
Q4: What shipping methods are common?
Sea freight (20–30 days) for bulk; air freight (5–7 days) for smaller, urgent orders.
