摘要： The present invention is related to a water dispersible paper, particularly for use in packages in the construction area. The dispersibility of the paper of the present invention is achieved due to the low wet resistance and high capillary absorption and basically consists of an unbleached cellulose-based paper aiming at the reduction of ingredients conventionally used, adding only defoamers and drainage aids in the formulation thereof. The paper of the present invention consists in the elimination of the use of disintegration aids (such as surfactants), gluing agents and dry resistance agents (such as starch). There is further described a manufacturing process for dispersible paper which allows obtaining a paper having low wet tensile strength and high capillary rise without the need for the chemical agents usually known for the manufacture of this type of paper. The present invention further foresees a package containing said paper for use in construction such as in packages for, lime, sand, cellulosic or synthetic fibers or powder pigments, among others.
