Abstract

An adsorption layer for retaining liquid or gaseous organic hydrocarbons prior to such matter reaching a sealing sheet of synthetic material. The adsorption layer includes activated carbon that is incorporated loosely or is bonded to the sealing sheet. Retention of the organic hydrocarbons in the adsorption layer prevents possible diffusion of this matter through the plastic sealing sheet.
