Abstract: A non-venting one-piece, partially perforated multilayer induction heat seal liner for a container that allows an aroma or scent from a solid substance within the sealed container to permeate through the liner, while preventing leakage and/or physical contact of the substance by the consumer. The liner includes a partial perforation extending completely through a metal foil layer, and leaving an un-perforated thickness in a paper layer. The partial perforation will allow a prospective customer to sniff the scent or aroma released through the partial perforation, while the liner remains secured to the container, extending shelf life of the substance, and preventing leakage, as well as, contamination, damage and/or reduced volume caused by consumers sampling the substance/product within the container.
