Its strong air permeability enables the paper to maintain good gas exchange when exposed to air, preventing the growth of mold due to long-term storage. This is also one of the key reasons why it is suitable for the restoration of ancient books. The outstanding advantage of flax paper is its excellent durability. The natural strength of flax fibers endows the paper with extremely high tear resistance and anti-aging ability, making it less likely to turn yellow or become brittle.

Whether it is ancient books and documents that have been preserved for a hundred years or artworks that need to be kept for a long time, using flax paper to carry them can greatly extend their lifespan. In addition, flax paper fully meets the requirements of environmental protection and degradability. Its raw materials are taken from renewable flax plants, and no excessive chemical additives are needed during the production process. After being discarded, it can quickly degrade in the natural environment without causing pollution to soil and water sources, which is in line with the current concept of green and sustainable developmen
