Method for irreversibly integrating adhesive authentication label in e.g. shrinkable envelope used to package e.g. money, involves realizing flexible package from films by shaping operations

摘要

The method involves bonding a first surface (1-1) of a label (1) with a part of inner faces (3-2, 4-2) of flexible plastic films (3, 4), and depositing adhesive on the inner faces of the films in order to allow bonding of a second surface (1-2) of the label with the films. The films superposed face each other by applying pressure on the films for ensuring bonding between the films and bonding of the second surface of the labels on the inner face of films. A flexible package (2) is realized from the films by shaping operations. An independent claim is also included for a flexible package.
