  • Publication number: 20220411149
    Abstract: Packaging may include a base box and a lid having a tamper-evident seal. The tamper-evident seal may include a paper substrate having a first adhesive portion configured to attach to a side panel of the base box, a second adhesive portion configured to attach to a second side panel of the lid. The first and second adhesive portions may be disposed on opposing sides of the paper substrate, and a tab configured to be accessible on an exterior of a package when the tamper-evident seal is applied may be a part of the paper substrate. When the tab is pulled with sufficient force, the paper substrate tears such that the first adhesive portion and the second adhesive portion remain fixed to the first and second side panels, respectively, while the remainder of the paper substrate tears free so that the packaging may be opened.
