PCT No. PCT/HU92/00015 Sec. 371 Date Dec. 10, 1993 Sec. 102(e) Date Dec. 10, 1993 PCT Filed Apr. 1, 1992 PCT Pub. No. WO92/18013 PCT Pub. Date Oct. 29, 1992.The invention relates to a cellulose-based package material having an increased adsorption capacity and a process for its manufacture. According to the invention, the package material is treated in a permanent manner with an aqueous suspension containing a mixture of fulvic acid and humic acid or salts thereof in the wet technological phase (step) of the paper manufacture. The treatment is carried out in the substance or on the surface of the package material during processing. The wet product obtained can subsequently be dried to a paper, paper board, cardboard, corrugated paper or other cellulose-based laminated product.
