FIELD: transportation.
SUBSTANCE: flexible container can be opened by breaking and is formed by forming a flexible film to make a container wall, making a barrier element for breaking with a breaking strength exceeding that of the wall film, arranging the element on or inside the film to form a breakage direction thereon and fixing the element on the film. Then the film is arranged so that to form a flexible wall container with opposing front and rear walls so as to the breakage line be located at the distance of, at least, one part, from the wall front wall to ease the container opening by limiting the breakage by the preset distance between the bands. The breakage barrier bands can be fixed on the film by an appropriate glue or be inserted in between the layers of the wall layered material.
EFFECT: provision of a barrier to prevent rupture propagation towards the container upper edge.
