Definitions

  • papers having a density in the range of 840-890 kg/m 3 , a strain at break in the MD in the range of 3.9-5.0%, a BRI in the MD in the range of 136-146 Nm 6 /kg 3 and a roughness of the printing side in the range of 241-310 ml/min.
  • "Axello White” having a density of 840 kg/m 3 , a strain at break in the MD of 2.2%, a BRI in the MD of 234 Nm 6 /kg 3 and a roughness of the printing side of 220 ml/min.
  • the calender used for the calendering of the first aspect is preferably a soft nip calender, i.e. a calender in which a nip is formed between a roll with a hard surface, such as a metal surface, and a roll with a soft surface, such as a polymer-covered roll.
  • the kraft paper of the first aspect is preferably a single-layer kraft paper.
  • a paper produced using two or more headboxes is not a "single-layer” paper according to the present disclosure.
  • a laminate is a "single-layer” paper according to the present disclosure.
  • a porous sack paper the combination of a relatively high stiffness and a relatively fine surface is of interest.
  • high stiffness is often beneficial when the sack paper is converted to sacks and a finer surface improves the quality of a print on the sack paper.
  • the sack paper of the second aspect is relatively porous in the sense that it has a Gurley value of less than 15 s.
  • a typical lower limit for the Gurley value is 2 s or 3 s.
  • the skilled person is knows how to produce sack paper of such Gurley values (see e.g. WO 99/02772 , which i.a. teaches to carry our HC refining, reduce the degree of LC refining (or even omit LC refining) and increase the dosing of strengthening agent).
  • the Gurley value is measured according to ISO 5636-5:2013.
  • the calender used for the calendering of the second aspect is preferably a soft nip calender (further discussed above in connection with the first aspect).
  • the strain at break in the cross direction (CD) of the kraft paper of the third aspect may be 6.0-10.0 %, such as 7.0-9.0 %.
  • Such a relatively high CD stretchability is beneficial as it results in high TEA values, which are beneficial in flour and sugar packages (to prevent package rupture).
  • the geometric tensile energy absorption (TEA) index of the kraft paper of the third aspect may for example be 1.9-2.2 J/g.
  • the TEA values are measured according to the standard SS-ISO 1924-3:2011. To obtain the TEA index, the TEA value is divided by the grammage.
  • the geometric tensile energy absorption (TEA) index of the kraft paper of the fourth aspect may for example be 2.4-2.8 J/g.
  • the Gurley value of the kraft paper of the fourth aspect is preferably 18-60 s, such as 20-40 s.
  • Table 1 Paper properties of wet-calendered paper and non-calendered paper. The sample taken "After jumbo roll and winding" was obtained from the top (i.e. an outer layer) of a customer roll.
