Multilayer composite for diffusing odorous substances and manufacturing method

摘要

The composite has an absorbent support-reservoir layer (1) designed to be printed and to receive an odorous substance (4). A polymer barrier layer (2) is positioned between a printable and/or printed support layer (3) and the absorbent support-reservoir layer to prevent migration of the substance between the support layers, where the printable and/or printed support layer is made of cellulose fibers. A hinge axis allows covering a first part of an outer face (1A) of the support-reservoir layer, which is not in contact with the barrier layer, on a second part of the outer face. Independent claims are also included for the following: (1) a method for producing a multilayer composite for diffusion of an odorous substance (2) a system for producing a multilayer composite for diffusion of an odorous substance.
