Fine Flute Bond (FFB) - Corrugated Gum
Fine flute bond (FFB) is partially hydrolyzed starches that are prepared by roasting in the presence of different catalysts. They are also available in chemical modified form also. This chemical and mechanical reaction reduces the large molecule size into small molecule with maintained viscosity.

Application
Application of FFB is in the fluting medium of paper box manufacturing. Take 125 lit, 150 lit, 175 lit, and 225 lit of the water respectively for the 1:5, 1:6, 1:7, and 1:9 ratio. According to the ratio need FFB is added to the decided amount of water with fast stirring in the vertex of the water till the paste is formed. For the FFB with the additive the given small bag of additive with FFB is added to the vertex of the water. For the one shot FFB, no need to add any chemical to the slurry of it.
