Acid-free paper is paper that remains neutral or slightly alkaline (in order to be neutralized by acids in air) in pH value after being dissolved in distilled water.
This paper acidifies slowly and is more resistant to deterioration. Thus it is more suitable for drawing, relics repair, antiques labeling, packaging and framing for a long-term preservation of valuable paper relics.
To promote the concept of preservation of paper relics, Chang Chuen Paper Mfg. Co., Ltd. A few years ago developed 100%-Kozo acid-free paper . Aside from high polymerisation and stability, an impressive recycling rate of up to 50~55% (vs. 30% that of Gampi and straw pulp) is one of the features of this 100%-Kozo acid-free paper.
The use of chemicals is greatly reduced in the production process of acid-free paper, and low-temperature drying is applied for preservation of the original fibers.

1.	Made from 100% Kozo for high strength.
2.	High polymerisation which attributes to higher stability and deterioration resistance.
3.	Chemical-free throughout the production and screening process.
4.	Low-temperature drying to maintain original fibers.
5.	The finished paper is slightly alkaline, in line with the 7.5 pH value of the USA Acid-free paper standard.
6.	Kozo acid-free paper maintains its neutrality after 108 years in the aging experiment, showing its slow acidification property.

1.	Calligraphy and drawing material (will be free from spots which occur after several years if the Shang paper is used).
2.	Repair of ancient calligraphy and drawing relics.
3.	Labelling and packaging of ancient cultural relics.
4.	Framing of calligraphy and drawing (in accordance with National Standard CNS P2068)
5.	Valuable family trees, musical scores, china/ceramics, photos, poems, hand-written documents,manuscripts, letters and other treasured calligraphy or painting.

For preservation purpose, the relic is covered with acid-free paper, with its smooth surface facing the relic and the rough surface facing the exterior.

1.	For a single piece of paper, use acid-free paper to cover both sides before storage.
2.	For a three-dimensional object, wrap with acid-free paper, then store in an acid-free box or storage room.
3.	For a scroll, wrap with acid-free paper, then store in a wooden box. The wooden box should possess high ventilation quality, for example,use paulownia tree or firwood.
