An apparatus for making a self-opening bag pack includes a supply of film material. An extruder forms a continuous tube of film. A flattener flattens the tube. A corona treater treats at least one surface of the flattened tube. A first sealer forms a bottom seam across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks at a predetermined distance from the bottom seam. A stacker forms the bag blanks into a bag pack. A non-linear adhesion knife penetrates the bag pack and adheres adjacent bag blanks together in the bag pack. An aperture maker forms means for suspending the pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag will be adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.

An apparatus for making a self-opening wide mouth bag pack includes a supply of flexible film material. An extruder forms a continuous tube. A flattener flattens the tube. A first sealer forms a bottom seal across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks has a bag mouth at a predetermined distance from the bottom seal. Second and third sealers form angled seals at lower corners of the bag blank forming a flat bottomed bag. An adhesion knife penetrates the bag pack adhering adjacent bag blanks together in the bag pack. An aperture maker forms apertures for suspending the bag pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag is adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.

A pinch bottom sack fillable with bulk good includes a sleeve with at least one area element, wherein the sleeve includes a mesh and the area element a handle means including a load element at which a load force is applicable for lifting the sack, and the load element is configured such that it extends at least in some areas at least in a load condition in which the load force acts at the load element opposite to an outer side of the area element.

A bag has a front panel, a back panel, and a gusset, each having a thermoplastic ply at its interior face. The interior face of the gusset is thermally welded to the interior face of the front panel and back panel at respective joins from which extend respective panel extensions which are also thermally welded to each other at a third join. Extensions of the gusset cover parts of the respective panels and are thermally welded to them. Other parts of the panel extensions are not covered by the gusset extensions and are welded to each other to form the third join. The extensions can form a handle part for the bag.

A rock bag and method of manufacturing same are provided herein. In one embodiment, the rock bag has a first set of opposed sides, each side of which is substantially the same dimensions, a second set of opposed sides, each side of which is substantially the same dimensions, and a bottom side formed to operatively couple with the first and second set of opposed sides such that the rock bag forms an enclosure with five sides and an opening opposite the bottom side. And the material forming the sides comprises between 40% and 90% rock content.

A pinch bottom sack fillable with bulk good includes a sleeve with at least one area element, wherein the sleeve includes a mesh and the area element a handle means including a load element at which a load force is applicable for lifting the sack, and the load element is configured such that it extends at least in some areas at least in a load condition in which the load force acts at the load element opposite to an outer side of the area element.

T-Shirt bag with a front foil layer, a rear foil layer and side folds, where the front foil layer and the rear foil layer and the two side folds at the bottom edge and at the top edge are joined together; and where at the top edge of the T-shirt bag two handles are formed by a recess, both handles being provided with a continuous suspension opening; where the perforation openings with incisions and a spot connection are provided in the front foil layer and in the front side fold portions of each handle.

A panel for a flexible package (100), and a method and system for forming the panel is provided. The panel comprises a first laminate having an open-area; a second laminate extending from a top edge to a bottom edge; and a third laminate, the third laminate sealed with the first laminate to cover the open-area, and the top edge and the bottom edge of the second laminate sealed between the first laminate and the third laminate such that area between the top edge and the bottom edge of the second laminate remains free forming a loop with the panel. The panel preferably forms a side-gusset (102) of a flexible packaging pouch, wherein the loop can be used as a handle (110) to carry the flexible package.

The invention relates to a production method of a material, a material and packaging intended mainly for food products. The design of the material used in the packaging machines allows for providing handles in the final packaging without the need for secondary operations. The handles are obtained through either placing a secondary narrower web onto the primary material, wherein the handle constitutes said web, or adjacent holes are cut in the primary material, wherein the handle is formed by the holes separating the primary material. A combination of these two methods or materials is also conceivable. In the area of holes, the primary material is joined with the secondary material, which is either a film or a membrane, wherein the secondary material is larger than the holes and it forms an overlap around them. The materials are joined in the overlap area around the inner circumference of the secondary material.
