Abstract: A protective pocket for stamps or similar products is provided with a contact adhesive in a sub-region of the lower film. An embodiment having a slit includes a lower film split in two. The split or unsplit lower film is provided in part with an extremely thin layer of contact adhesive. The covering, however, covers not only the contact adhesive but the entire lower film, and is thus matched in accurately fitted fashion to the outside dimensions of the strips, so that there are only slight height differences in the stacked strips. These stacks can readily be processed into protective pockets.
