There is a file box that everyone is familiar with in office supplies. Among them, kraft paper file boxes and plastic file boxes are the most common ones that everyone comes into contact with. In fact, in addition to these materials, there are some other better materials that can be used as document boxes. So what material is used for the document file box to have a better environmental protection effect, and the storage time is longer?

First of all, we must understand that the current file box mainly has three materials: PVC plastic, cardboard and acid-free paper.

1. PVC material

PVC is abrasion-resistant and moisture-proof, but it is easy to age and become brittle over time (if the climate in your place is relatively humid, it is recommended that you can choose PVC material)

2. Cardboard material

Cardboard has a long storage time, but it is easily affected by humid air (if storage time is required, cardboard can be used)

3. Acid-free paper material

Relatively speaking, acid-free paper is more durable and environmentally friendly. The acid-free paper archive box has no acidity, is firm, and has high strength. It is made by planting plant fiber pulp to eliminate the organic acids present in it and making it on a paper machine.
