A substantial quantity of paper is produced worldwide from recycled fibers. With each recycle, length and strength of fibers go down as the cellulose chains break. In order to increase strength properties of paper there are a number of options available to the papermakers. Most of the modified starches and other chemicals do improve the bursting strength, tensile strength and similar properties. However, some of the strength properties like Tear, RCT, CMT are more dependent on the type, chain length and strength of the fibers used in papermaking and are, therefore, difficult to improve.
