ABSTRACT:
Packets containing a flowable material are provided with a draw-string or thread to squeeze the packet contents. The packet envelope is formed from a doubled-over web which gives the packet a folded-over edge and which encloses an intermediate portion of the thread close to the folded-over edge. The end portions of the web extend from the intermediate portion of the thread to extend through the opposite edge of the packet. The external ends of the thread are secured to a tag which is attached to the outer face of the envelope. The thread intermediate portion is retained close to said one edge by heat seal means. Apparatus is also described for producing the packets in a continuous or semi-continuous manner.
