Sodium polyborate as a flame retardant for kraft paper

We believe that soufa is likely to be used as a kraft paper flame retardant.
Soufa is sodium polyborate, which has been shown to impart high flame retardancy to cellulosic materials.

Some companies have also begun testing on kraft paper, and generally have shown good results.

Although it has nothing to do with our company, it seems that Toppan Printing has developed a non-combustible paper tube.
I think this is a wonderful technology for stacking non-combustible paper.
