Abstract

The kraft paper is used for making ventil bags of one or more layers. The method consists in subjecting sulphate pulp to HC-refining in or in HC-refining in combination with LC-crushing. The LC-crushing is made at relatively low energy supply where the intensifying agent, in particular, expanded polymer, is subsequently added to the blank, preferably in two separate stages of the process, in total quantity of at least 8 kg for 1 t of paper, The kraft paper has absorption index of the stretching energy of 2.5-3.5 J/g, at porosity not exceeding 10 s. 25 claims, 2 figures
