Abstract

La presente invención se refiere, a un papel dispersible en agua, especialmente para su uso en envases en la industria de la construcción civil. La dispersabilidad del papel de la presente invención se logra debido a la baja resistencia en húmedo y alta absorción capilar y consiste básicamente en un papel "unbleached" o sin blanquear a base de celulosa, con el objetivo de reducir los ingredientes utilizados convencionalmente, agregando solo antiespumantes y coadyuvantes de drenaje en su formulación. El papel de la presente invención es eliminar el uso de auxiliares de desintegración (como los tensioactivos), agentes de encolado y agentes de resistencia en seco (como el almidón). También se describe un proceso de fabricación de papel dispersible que permite obtener un papel con baja resistencia a la tracción en húmedo y alta absorción capilar sin necesidad de los agentes químicos habitualmente conocidos para la fabricación de este tipo de papel. La presente invención también prevé un envase que contenga dicho papel, así como el uso del papel en la construcción civil, tales como envases de cemento, cal, arena, fibras celulósicas o sintéticas o pigmentos en polvo, entre otros.
