Thousands of years of aging aging paper come out

Plain paper containing residual lignin is extremely susceptible to aging by corrosion of acidic gases, and even high-quality paper will age and deteriorate decades later. Oji Paper Co. uses a special drug to bleach the pulp twice, greatly reducing the amount of lignin left, thereby preventing paper aging and improving the whiteness of the paper.

Writing or printing academic papers, almanacs, dictionaries, etc. with this new paper can basically be preserved for thousands of years without fading or yellowing.
