ABSTRACT:
A tagged packet carries a tag which is attached to the main body of the packet by a thread. The thread comprises polypropylene so as to be attachable by heat sealing to the body. The body is made up of layers of sheet material also comprising thermoplastic material to allow the body to be closed by heat seals. The thread is secured to the f ace of the body at one edge at the same time as that edge is heat sealed and the heating for the thread seal is applied from the opposite face of the body whereas the adjacent regions of edge seal spaced from the thread has the heating applied through the first face. This arrangement gives closer control of the different conditions required for securing the thread and for sealing together only the sheet material of the body.
