Abstract
The envelope (100) has an additional flap (103) extending externally by superposition, being connected to the main portion (101) via two parallel lines of heat sealing (102, 105). According to the invention, the additional flap (103) has a reinforcing strip (106) applied thereto and at least one cutout (110) is formed therein to define the outline of a pull tongue (114). The cutout (110) extends beyond the reinforcing strip (106) in the form of two slots (113) formed through the wall of the flap and forming tear starters. The flap also has a line of perforations (104) extending parallel to the direction of the reinforcing strip (106) and at a distance therefrom, so as to enable the panel which is obtained by tearing the corresponding portion of said flap to be detached.
