With the concept of national environmental protection deeply rooted in people's hearts and the continuous advancement of the "Plastic Restriction Order", the field of book packaging is ushering in a green transformation. Biodegradable bags, with their advantages of environmental protection, adaptability and durability, are gradually replacing traditional plastic bags and becoming the preferred choice for publishers and bookstores. As a carrier of knowledge, book packaging is not only related to transportation safety, but also reflects the environmental responsibility of enterprises. The biodegradable bags produced by Jiuxinda Factory accurately meet the needs of book packaging and inject motivation into the green development of the industry.

Transport packaging is a key guarantee in the book circulation link, directly determining whether books can reach consumers in good condition. Books have special materials; the paper is fragile and easy to fold and get damp. Squeezing, friction and moisture intrusion during transportation may cause damage, affecting the reading experience and product quality. Biodegradable bags have good toughness and sealing performance. They can not only effectively buffer the impact force during transportation, avoid the folding of book corners and the dampness of inner pages, but also fit the size of books, adapt to the packaging of books of different formats without additional cutting, taking into account practicality and convenience. Compared with traditional packaging, it is light in texture but good in load-bearing capacity, can be stacked for storage, saves transportation space, reduces logistics costs, and can clearly present book information, facilitating warehousing sorting and consumer identification.

Compared with traditional plastic bags, biodegradable bags show irreplaceable advantages in book packaging. Traditional plastic bags are hard in material, insufficient in toughness, easy to break and non-degradable. After being discarded, they remain for a long time to form "white pollution", which not only violates the concept of environmental protection, but also does not meet the current policy requirements. In addition, their sealing performance is poor, making it difficult to effectively protect books from moisture. Biodegradable bags adopt PLA+PBAT composite degradable raw materials. After being discarded, they can be completely degraded into water and carbon dioxide in the natural environment without any environmental residues, reducing a large number of plastic wastes every year and conforming to the trend of green development. At the same time, it is soft in texture but not easy to break, has excellent moisture-proof and anti-fouling performance, can better protect books, and can be customized for printing. Publishers can print brand logos and environmental protection slogans, taking into account the practicality of packaging and brand communication.
