Abstract

As it is known, the low flame resistance is one of the negative characteristic features of Kraft papers which find a wide usage area. This feature needs to be improved especially in paper types that will be used for archival-storage and protection purposes. The aim of this study was to increase the flame resistance of Kraft-based paper materials (envelope, box, etc.) to be used for the purpose of storage-archive. In this study, MCC (microcrystalline cellulose) / CMC (carboxymethyl cellulose) reinforced lignin, tannin and borax were used. The immersion method was chosen for the application of chemicals. Limited oxygen index levels (LOI) and UL-94 flammability tests were performed on the treated papers to determine their burning characteristics and flame resistance properties. As a result of this study, it was seen that the chemicals applied to the kraft papers by immersion method improved the fire resistance properties and also positive results have been obtained especially with MCC/CMC reinforcement.
