Abstract: The method and the bag find broad application in civil engineering for filling of bags with cement and other bulk materials. They improve the characteristics of extension and porosity, and reduced production costs. The method for making kraft paper weighing from 50 to 140 g/m2 and absorption index of energy of extension of 2.3 to 3.5 J/g in porosity of Gurley less than 7 s, includes steps of substrating sulphate pulp only of highly consistent refining or combined effect of consistent refining and low consistence splitting. Then acceleration agent is added, in particular filled polymer such as starch, to the treated material. This addition is made before the material is fed to the paper machine. The high consistence refining is effected by maintaining energy supply of no less than 150 kWh per ton of paper, calculated for 100% dry paper. The acceleration agent is added to the treated material in two or more steps, and in the first and second step no less than 5 kg have to be added per ton dry paper. 20 claims, 2 figures
