Abstract
A multilayer structure () for volatile substances diffusers includes a semi-permeable layer () that can be in contact with the volatile substances and a barrier layer () to prevent the diffusion of the volatile substances before removal of the barrier layer from the multilayer structure. The multilayer structure also comprises a tear layer () placed between the barrier layer () and the semi-permeable layer (), which permits the separation of the barrier layer () from the semi-permeable layer () when the barrier layer () is removed from the multilayer structure (). The tear layer provides a suitable interface strength between the barrier layer and the semi-permeable layer and allows for the secure and easy removal of the barrier layer from the semi-permeable layer.
