20140314344 | Packaging container for bulk materials - The requirement consists in designing and producing a packaging container for bulk materials, in particular sacks or bags, made of a flexible plastic film with a venting facility, in a particular simple manner. This requirement is met in that the flexible plastic film is designed, at least in a partial area, in two layers, in that the inner layer of the plastic film comprises inner venting openings, in that the outer layer comprises outer venting openings and in that the inner venting openings and the outer venting openings are spaced apart from each other. | 10-23-2014 |
20140241649 | PACKAGING CONTAINER THAT CAN BE VENTILATED - A particularly simple construction is intended for a packaging container for bulk material, in particular a sack or bag made of a plastic film with at least one container wall which encloses the bulk material, which comprises a multilayer venting region extending in the longitudinal direction of the container and consisting of at least one inner layer and one outer layer, wherein the venting region has at least one inner and outer opening, wherein the inner openings are designed as apertures in a strip-shaped surface region of the inner layer of the venting region, wherein the surface region extends over at least a portion of the direction of extent of the venting region, and wherein the at least one outer opening is formed in a joining seam laterally limiting the venting region, wherein a shielding element inside the venting region is associated with the outer opening in the joining seam for the deliberate diversion of at least a partial flow of the air flow passing through the venting region. This is achieved as a result of the venting region having just one chamber in which the shielding element separates the inner and outer openings from each other and the shielding element has a length that is between 10% and 50% of the overall length of the venting region. | 08-28-2014 |
20120269464 | CONTAINER FOR PACKAGING FILLING MATERIALS AND METHOD FOR PROCESSING A WEB MATERIAL - In a container for packaging filling materials, in particular a bag or pouch made of plastic film, comprising at least one container wall surrounding the filling material, which has at least one front and rear wall, and comprising superposed layers formed in the top region of the container, wherein in the top region of the container predetermined layers are connected over at least one section by means of at least one closure means closing the container, below which a section of the top region located adjacent to the region fitted with the opening has a filling material withdrawal region and that at least one section of a connecting seam is disposed so that it runs around an opening at least in some areas in such a manner that in the top region the multilayer region is separated in a sealing manner from the filling space of the container. | 10-25-2012 |
