The individual packets can be overlapped and mounted on a display unit. Each packet has a projecting strip of its upper edge extending across the filling cavity and over which the packets are joined firmly together through several welding apertures. Holes for suspending the packets ae located between the welding apertures. The front part of a each packet is separate from the strip while the back part is connected to the strip by a perforated section. |
