The use of envelopes and tattoos is effective in maintaining the shape of paper materials and preventing deterioration due to light and dust when storing paper materials for a long period of time.
We handcraft storage containers one by one as needed. Regarding the shape and material of the container, we will make the necessary container while consulting each time. Please use it to store and use materials whose cover is fragile or whose shape is unstable.
* What is PAT (Photographic Activity Test)?
PAT explores the potential for scientific interactions between photographs and specific materials after prolonged contact.
In the field of document storage, it is also adopted as one of the criteria for judging the safety of storage containers and acid-free paper products.
Effective for storing thick simple bookbinding, leather binding, and fine binding. Alkaline paper (PAT passed product) is used, and the color can be selected from dark gray, beige, and light gray. A neutral bond (pH about 7.5, PAT passed product) is used for adhesion.
Our company has a structure with few irregularities on the surface, which makes it easy to put in and take out when arranging. Please use it to store materials that have been deacidified.
Suitable for storing thin booklets such as notebooks and magazines and Japanese-style books. Alkaline paper (PAT passed product) is used for the holder part, and the color can be selected from dark gray, beige, and light gray. Neutral paper (PAT passed product) is used for the inner part, and neutral bond (pH about 7.5, PAT passed product) is used for adhesion.
The material, which is thick to some extent, has a structure that can withstand pressure from the side by supporting the side surface of the part.
Envelope with transparent window
An envelope with a large polyester window that allows you to see the contents at a glance, which is effective for storing thin booklets and leaf materials. Alkaline paper (pH 8-9, PAT accepted product) is used for the paper part, and a thermoplastic adhesive is used for adhesion. The color is beige only.
Not only paper materials that require visual information, but also vulnerable materials can be safely stored. It is easy to handle because you can check valuable books and documents that you do not want to get dust or fingerprints without taking them out. In addition, since the envelope itself is made of cardboard, it can stand on its own even with leaf materials.
