  • MULTILAYER STRUCTURE FOR DIFFUSION OF VOLATILE SUBSTANCES
    Publication number: 20190337265
    Abstract: A multilayer structure (1) for volatile substances diffusers includes a semi-permeable layer (2) that can be in contact with the volatile substances and a barrier layer (3) 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 (4) placed between the barrier layer (3) and the semi-permeable layer (2), which permits the separation of the barrier layer (3) from the semi-permeable layer (2) when the barrier layer (3) is removed from the multilayer structure (1). 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.
