“…All are sensitive in various degrees to basis weight, fiber furnish, fiber-fiber bonding (density), fiber orientation, pulp yield, dry strain, strength additives, and other factors. Thus, linerboard manufacture requires adjustment of these to produce the proper blend of property values for end use (Chalmers, 2001).…”

“…This undulated layer of the corrugated board, so called fluting, is characterized by good absorption properties and cartons made from it provide satisfactory protection for packed products against mechanical damage (Modzelewska, 2006). It is usually made from semi-chemical pulps of broad-leaved wood (short fibers) or recycled fiber (mostly from used containers) (Chalmers, 2001 andJakowski, 2005). Currently, in addition, ground wood pulp or pulped waste paper is added, which has a positive influence on the price and ecological evaluation of the final product (Tarnawski, 2003 andJakowski, 2005).…”

“…Most domestic medium is made on fourdrinier paper machines at a nominal grade weight of 127 gm -1 and a thickness of 0.23 mm or more. Heavier weights are made; up to ~ 205 gm -1 , to meet special packaging needs (Chalmers, 2001).…”

“…This mechano-sorptive effect is much more severe than for storage in high humidity alone and to allow for this phenomenon an allowance needs to be built into the box performance specifications over and above those anticipated for high-humidity environments. (Chalmers, 2001) Measurement requirements in the manufacture of paper and board for packing purposes are exposed to great stresses. The function of the packing is to protect goods during transport and storage and in many cases it must also provide a surface for the presentation of printed information about the contents.…”
