  • Membrane permeable to aromatic products
    Patent number: 6902817
    Abstract: A multilayer structure with improved permeation for atmospheric diffusion of aromatic products wherein the structure comprises: a permeable membrane wherein said permeable membrane comprises at least two polymeric layers wherein the polymer of each layer is independently selected from the group consisting of polyethylene, very low density polyethylene, low density polyethylene, ethylene methylacrylate copolymer; a release layer wherein said release layer comprises a nylon polymer or a ethylene vinyl alcohol copolymer wherein the release layer is adhered to most inner polymeric layer of the permeable member which comprises the permeable membrane and wherein the adhesion between release layer and the adjacent layer of the polymeric permeable membrane is a relatively weak bond compared to the bond between the layers of the polymeric permeable membrane; and an impermeable membrane wherein said impermeable membrane comprises one or more layers wherein the materials which comprise the individual layers of the imper
