make not only bag and 

 wrapped paper, but also 

 board paper. Today, 

 linerboard is one of the 

 mainstays in the southern 

 paper industry. 



Introduction of continuous 

 digesters and high-capacity 

 chemical recovery boilers, 

 plus constant research into 

 refinement of pulping 

 techniques, bleaching 

 processes, and blending of 

 hardwood pulps with various 

 pine pulps, has developed 

 a highly diverse industry. 

 Using southern tree species, 

 the industry today 

 manufactures newsprint, 

 linerboard, fine writing 

 papers, label papers, 

 magazine stock, coated 

 and uncoated bleached 

 board, and other items to 

 package anything you can 

 find at a fast food restaurant, 

 in your refrigerator, or in 

 your microwave oven. 



While the industry has 

 grown tremendously in its 

 use of southern pines, it 

 has continued to search for 

 uses for the plentiful and 

 underutilized low-grade 

 hardwoods found 

 throughout the South. 

 Typical of the results of this 

 effort is the development of 

 Chemfibre, a corrugating 

 material, patented by 

 International Paper 

 Company and used in the 

 manufacture of shipping 



containers. The middle 

 layer of this shipping 

 container is made from 

 hardwood pulp. 



The St. Francisville Paper 

 Company in Louisiana was 

 built as a joint venture of 

 Crown-Zellerbach 

 Corporation and Time, Inc. 

 This 225-ton-per-day mill 

 has the distinction of being 

 the first southern mill to 

 use only hardwoods in the 

 manufacture of coated 

 printing papers. 



Nearby at Natchez, MS, in 

 1950, International Paper 

 Company built the first mill 

 of its kind in the world, 

 manufacturing rayon pulp, 

 using the sulfate process 

 and utilizing hardwood 

 pulpwood. 



Constant research, largely 

 proprietary and well 

 guarded by various industry 

 members, has dramatically 

 increased hardwood usage, 

 frequently blending 

 hardwood pulp with pine in 

 various combinations to 

 reduce product cost, while 

 in many cases improving 

 such aspects of the product 

 as smoothness and 

 printability. 



While much research effort 

 has been devoted to pine 

 and hardwood pulpwood 

 and their usage in the pulp 

 and paper industry, one of
