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.

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.

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.

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.

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 process for manufacturing bags made of a biodegradable or biodegradable-compostable plastic material and without any bellows, said process comprising the following sequence of steps: loading a reel (12) of plastic film (13) obtained by blown-film extrusion and having a width which corresponds to the width of at least one bag (50) to be formed; longitudinally cutting along cutting lines (15) to form at least two longitudinal bands (13); separating the bands to a given D distance from each other, and longitudinally welding; said steps being a function of the transversal dimension or width of the bag to be manufactured; transversally welding each individual longitudinal band (13) to define band portions (27) which corresponds to the longitudinal dimensions of the bags (50) to be formed, punching said band portions (27), moving and unloading the bags (50) thus formed.

The invention describes a bag (300) having a first wall and a second wall that comprise paper and that are connected to one another by lateral edges such that a fill space is provided, wherein the second wall projects above the first wall as seen in the longitudinal direction of the bag, and having two ends, wherein a bottom is arranged on one end and an opening is provided on the other end, through which the fill space is accessible, wherein the bottom comprises at least one folding region of the second wall, wherein the folding region is folded over at least parts of the first wall about a crease line, and having at least one handle opening (109, 109).

The invention is characterized by the handle opening (109, 109) through which the second wall reaches outside of the folding region and through the folding region.

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.

A method for making a film bag with reinforced bag seams includes a film extruder that produces a continuous tube of film. A flattener produces a continuous web of flattened film which has an upper surface and a lower surface. A fold maker has a receiving portion positioned above the web and a displacing portion is positioned below the web that moves cyclically upward to a first position to locate a portion of the web into the receiving portion, thereby forming a fold. A fold retention device prevents the fold from opening. A presser flattens the fold against the web. A sealer seals through the fold, forming a reinforced bag seam. A cutter severs a sealed portion from an unsealed portion of the web. A transport mechanism moves the film from the extruder, through the flattener, into the fold maker, beneath the presser, into the sealer and to the cutter.

A bag including a containment portion having an opening to receive items, a bag seal at an end of the bag opposite the opening, a handle seal at an end of the containment portion opposite the opening, the handle seal located between the bag seal and the opening, and a handle in a handle body formed between the handle seal and the bag seal.
