Top 5 Biodegradable Bag Manufacturers in China

Overview of China’s Biodegradable Bag Industry: Market Structure and Development Trends

The biodegradable bag industry is growing rapidly under global trends like “plastic restriction,” “carbon neutrality,” and sustainable consumption. MarketsandMarkets predicts the global biodegradable plastics market will exceed USD 20 billion by 2030, with a CAGR of over 9%. China is both a leading consumer and a major manufacturing and export base.

Since 2020, Chinese policies such as the “Plastic Pollution Control Action Plan” and the “Dual Carbon Strategy” require major cities to phase out non-biodegradable plastic bags by 2025, accelerating industry upgrades and creating a complete ecosystem from raw material R&D to manufacturing and export.

The industry chain includes:

• Upstream raw materials: PLA, PBAT, and PHA.
• Midstream manufacturing: Film blowing, injection molding, thermoforming, printing, sealing, and packaging.
• Downstream applications: Supermarket and retail bags, garbage bags, mailing bags, food packaging, and pet waste bags.

China leads globally in PLA modification, smart production, and composite material innovation, with exports primarily to Europe, Australia, South America, and Southeast Asia, accounting for about 45% of global supply.
