Abstract (en)

A wall material for a construction of a flexible container that is designed to be openable by tearing is formed by providing a flexible film for forming a wall of the container, providing a tear barrier element having greater tear resistance than the wall film, locating the element on or within the film to define a tear path thereon, and fixing the element to the film. The film is then arranged to form a flexible-walled container having opposed back and front walls, so that the tear path is spaced from at least a part of the top edge thereof and facilitates opening of the container by restricting tearing to the path defined between the strips. The tear barrier strips may be located to be fixed on the film by means of suitable adhesive or may be embedded between laminate layers of the wall material. <IMAGE> <IMAGE>
