A long time ago, "kraft" really is calf hide. Of course, this "kraft" only now do drum skin when it will be used; and you use 

brown paper bag book, is that people have learned paper technology in the future, with conifer wood fiber after chemical 

pulping , and then into the beater beating, then add glue, dyes, etc. Finally, in the paper machine into paper copy. Because 

of this the paper color is brown, papery tenacity, much like leather, so people call it kraft paper.

In fact, the method for producing kraft paper and plain paper and not much different. Why is stronger than ordinary kraft paper

do? This is mainly kraft wood fibers used in long, but also in the cooking timber, with caustic soda and sodium sulfide 

chemicals to handle, so they played the role of chemistry more relaxed, original wood fiber strength suffered damage relatively 

small, between this and therefore made out of paper pulp, fiber and fiber is tightly dependent, so the kraft paper are very firmly.
