Estimating the term…
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.
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, wherein in the base region of the container between front and rear wall, two inner layers of an interfolding of a web section of the plastic film, which is folded inwards at least on one side on one of its longitudinal sides, are disposed, wherein a standing base connecting the front and rear wall is formed by means of the interfolding, and comprising a multilayer region comprising more than two superposed layers formed in the top region of the container, wherein the multilayer region has at least one carrying aid formed as an opening, which opening passes at least partially through the layers in the top region, and comprising seams connecting predetermined layers in the side regions and in the top region, wherein the top region 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 the 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.
Method for processing a web material for packaging containers made of plastic film, in particular for film pouches having standing bases, in which at least one flat web is folded to form a folded web having superposed outer and inner layers on both sides along the longitudinal sides, wherein the subsequent standing base is produced at least on one of the longitudinal sides of the folded web to be produced by folding the folded web longitudinal side inwards and wherein on the opposite longitudinal side of the folded web forming the subsequent multilayer top region, the marginal edges of the flat web forming the ends of specific layers not connected to one another are superposed, a reclosure is inserted between predetermined surface sections of layers of the folded web not connected to one another at least in certain sections, predetermined surface regions of the superposed layers of the folded web are then connected to the reclosure and to one another in the longitudinal direction of the folded web by means of at least one section of a closure seam of at least tubular sections each having a multilayer region separated from the interior of the tubular section is produced, in the separated multilayer region of each tubular section of the strand at least a certain number of the superposed layers are cut through to form at least one intervention and the strand is then rolled up to form a coil for further processing.
Method for processing a web material for packaging containers made of plastic film, in particular for film bags having standing bases, in which at least one tubular web is folded to form a flat tube having superposed outer and inner layers on both sides along the longitudinal sides, wherein the subsequent standing base is produced at least on one of the longitudinal sides of the flat tube to be produced by folding the tubular web longitudinal side inwards and along the opposite longitudinal side of the flat tube forming the subsequent multilayer top region comprising more than two superposed layers, predetermined layers on at least one folding edge interconnecting the layers are at least partially separated and a material web having folded web sections is produced, a reclosure is inserted between predetermined surface sections of the layers at least partially separated at their folding edges, surfaces regions at least of the separated layers of the folded web sections are connected to the reclosure and to one another in the longitudinal direction of the material web by means of at least one section of a closure seam, and at least one strand of at least tubular sections having respectively one multilayer region separated from the interior of the tubular section is produced, in the separated multilayer region of each tubular section of the strand, at least a certain number of the superposed layers is cut through to form at least one intervention and then the prefabricated strand is rolled up to form a coil.
