A bag with handle and method for producing the bag that incorporates the features of four seal bag body with a new handle part to obtain a new bag with a durable bag body that can carry a heavy load, can be stacked in high number without falling, consume less space in storage and transportation, has large front space and side spaces for product information display while on shelf, that is convenient to hold, strong and secure, that does not cut fingers in use, and that may be applied to shopping bags or reusable or resealable packaging bags. The concept of the method of producing said bag is steps of folding, assembling, and sealing a plurality of sheet materials which are not obvious to a person ordinarily skilled in the art.

A bag with improved carry handle strength and stand-up ability and method of constructing same using an algorithm that takes into account one or more bag traits resulting in an upper bag portion configuration constructed to carry a predetermined volume of contents within the bag body.

A method is disclosed for forming a windowed packaging material. According to the method a web of packaging material is cut in substantially the machine direction along a non-linear path. The cutting action provides two subwebs, each having protruding edge portions and recessed edge portions. The two subwebs are displaced relative to one another so that the protruding edge portions face one another. In this configuration opposing recessed edge portions form windows. The two subwebs are adhered to one another at the opposing protruding edge portions. The resulting windows may be covered with a material that is transparent and/or breathable. A strip of handle material may be applied spanning the respective windows.

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.

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.

A flexible material package (100, 200) is presented comprising a reinforcing element (3) and a first sealed area (103) positioned close to the upper end of the package (100, 200) and preferably configured so as to close the package (100, 200), wherein the reinforcing element (3) is at least partially positioned within the first sealed area (103), the package (100, 200) further comprising gripping means positioned vertically below the reinforcing element (3) and configured so as to be used to support the package (100, 200). A closing method, a filling method and a formation method of the package (100, 200) are also presented.

A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

The invention describes a pouch-type bag, with a first wall and with a second wall, which comprise paper and which are connected to one another via side edges, so that a filling space is provided, wherein the second wall, viewed in the longitudinal direction of the pouch, protrudes beyond the first wall, with two ends, wherein a base is arranged at one end, which base comprises at least one envelope area of the second wall, wherein the envelope area is folded over about a first crease line at least onto parts of the first wall, wherein an opening is provided at the other end, via which opening the filling space is accessible, wherein one of the walls comprises a sealing area which can be folded over about a second crease line onto the outside of the other wall and can be fastened there by means of an adhesive element applied to the sealing area.

The sealing area comprises a tear-off aid between the second crease line and the adhesive element, with which the sealing area can be at least partially severed to allow renewed access to the filling space.
