Abstract
"PROCEDURE FOR WATERPROOFING AND FINISHING PAPER PACKAGING" characterized in that a product prepared from a mixture of water repellent substances such as proteins, nitrocellulose, amylate solution with a pH less than seven, with waterproofing substances in proportion adequate, it is administered on the external surfaces to the already built containers by subjecting them to drying for several hours, in order to prevent in the resulting product the absorption of water and the consequent loss of qualities, by effect of the combined action of the repulsion between the molecule of water and that of the repellent, by closing the pores of the paper by the waterproofing.
