With the development of the economy and society, plastic packaging has caused increasing environmental pollution, affecting human survival and development. Therefore, scientists have been committed to researching environmentally friendly materials that can replace plastic in the past decade. Now, our company has launched several express delivery bags made of fully biodegradable materials. What is the difference between biodegradable express delivery bags and ordinary express delivery bags? Today, I will explain to you:

1. Material difference: The main components of biodegradable express bags are PLA and PBAT, as well as some starch or calcium carbonate components. These materials are harmless to the environment and can be directly degraded into water and carbon dioxide under certain conditions, so they can be directly treated as composting materials. The main component of ordinary express bags is polyethylene plastic. If it can be recycled and reused after use, it will not cause significant environmental pollution. However, if it is not recycled and directly treated as garbage for landfill, it cannot be degraded for decades. Even incineration can produce harmful gases. Therefore, in terms of environmental protection, biodegradable express bags are the future development direction.

2. Price difference: The cost difference between biodegradable materials and plastic polyethylene is still quite significant. Currently, biodegradable materials are priced at around 25000 yuan/ton for raw materials on the market, while plastic polyethylene costs 9000 yuan/ton. Therefore, in terms of cost-effectiveness, the cost of ordinary express bags is lower.

3. Performance difference: After more than a decade of development, the physical properties of biodegradable materials have gradually improved, reaching 80% of the physical properties of traditional plastics, and can be used in various application scenarios. Currently, postal, Tmall, and JD.com have begun to promote the large-scale use of biodegradable express bags.

Although the cost of biodegradable express bags is about three times higher than that of ordinary express bags, the production process and technology are also basically mature, and they are environmentally friendly, reducing air and soil pollution in the environment. Therefore, biodegradable express bags will become the most important development direction for future express packaging.
