Driven by environmental policies and market demand, degradable packaging bags are gradually replacing traditional plastic products and 

becoming a new trend in the packaging industry. Governments of various countries have passed legislation to restrict the use of disposable plastics, 

while encouraging the research and development and application of degradable materials to promote the transformation of the plastics industry 

towards sustainable development.

Policy-driven: The pace of global "plastic ban" has accelerated

In recent years, many governments have successively introduced policies to restrict or ban the use of non-degradable plastics. Countries and regions 

such as the European Union, China, and India have passed legislation to gradually phase out disposable plastic products and encourage companies to 

adopt degradable alternatives. These policies not only cover industries such as retail and catering, but also involve emerging fields such as express packaging, 

providing strong support for the popularization of degradable packaging.

Technological progress: reduced cost of degradable materials

The promotion of degradable packaging was once limited by high costs, but with the development of technology, the production capacity of materials 

such as PLA and PBAT has increased, and the price has dropped significantly. Large-scale production has made the economic efficiency of degradable 

packaging gradually close to that of traditional plastics, laying the foundation for large-scale application.

Challenges and future directions

Although biodegradable packaging has broad prospects, it still faces problems such as the reliance on industrial composting for degradation conditions 

and insufficient consumer awareness of classification. In the future, policy refinement, technical optimization and public education need to be promoted 

simultaneously to ensure that biodegradable packaging can truly play an environmental role.

[Conclusion]

The popularization of biodegradable packaging is an important step in the governance of plastic pollution, but its long-term effect still depends on the 

collaborative efforts of the entire industry chain. Driven by global policies and market demand, the plastics industry is ushering in profound changes.
