Title:
PAPER BAG HAVING BAG CONTENTS
Document Type and Number:
WIPO Patent Application WO/2023/173148
Kind Code:
A1
Abstract:
The invention relates to a paper bag having bag contents to be mixed with water, e.g. having a building material such as dry mortar, cement, gypsum, lime and refractory compounds, wherein it is already known that the paper bag contains a disintegration agent so that the bag disintegrates when the bag contents and water are mixed together, and the paper bag does not have to be disposed of separately. A disadvantage of this is that these bags are not very stable mechanically and in terms of storage. According to the invention, the bag contents comprise the disintegration agent for the paper bag, meaning that the bag loses its stability only when its contents comes into contact with water and thus the disintegration agent becomes effective. The disintegration agent or one of the disintegration agents is preferably a wetting agent, a dispersing agent, a surfactant, a flow agent, a disintegration aid (debonding agent) for paper disintegration into paper pulps, or a base. The at least one disintegration agent can also be a substance combination, wherein one part of the substance combination is contained in the material of the paper bag (bag paper or bag adhesive) and the other part of the substance combination is contained in the bag contents.
