Abstract
Label-like, hermetically-sealed perfume pouch samplers with artwork on their top surface and a pressure sensitive adhesive bottom surface. The adhesive bottom surface may be employed to attach the pouch labels to pages of a magazine or other mailer, providing an efficient method of mass distribution of perfume samples. The fragrance is stored in a perfume-releasing article such as an ultraviolet radiation-cured perfume-doped polymer, or a fragrance-laden polymer gel of modified cellulosic, ethyl alcohol, fragrance oil, an antioxidant, and water, surrounded by two perfume impervious sealed barrier layers. There is disclosed a method of manufacturing the perfume pouch labels on a support web that can be wound onto rolls from which the pouch labels may be readily released and applied rapidly and precisely to advertising pages.
