Zero SpanTensile Strength (Paper): This provide an idea of tensile strength of fiber and not the strength of fiber bonding. The gauge length of the tensile strength measuring instrument is set to zero so the failure is by fiber rapture only. It is measured with a strip of paper but mainly a pulp property.
Hardness and Compressibility: Hardness is the property of paper that causes it to resist indentation by another material. Normally a soft cooked pulp will produce soft paper and vice-versa. Compressibility is defined as the reciprocal of the bulk modulus. It can be measured under static load by determining the change in caliper of the sheet under and expressing the results as a function of pressure.

13, 2017 - At the inaugural Eco-Certifications Appreciation Lunch this week, the Singapore Environment Council (SEC) announced that consumer goods company Kimberly-Clark has become the first to have 12 of its pulp and paper products become certified under the enhanced version of SEC’s Green Labelling Scheme.
11, 2017 - Andritz has received an order to modernize the stock preparation line in the sack kraft paper production line at Mariysky Pulp and Paper Mill in Volzhsk, Russia.
23, 2017 - Archroma, a colour and specialty chemicals company, has introduced Cartaspers PLH liquid, a one-product, organic additive that delivers “easy and highly-effective” control of pitch and stickies deposition in soft water pulp and papermaking environments.
