A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

A side gusset paper container in which in the region of the transition of the front wall to a first part of the container bottom region, there is a first pre-crease, and in which in the region of the transition of the rear wall into a second part of the container bottom region, there is a second pre-crease. Furthermore, the disclosure relates to a method for producing a side gusset paper container, in which at least one or a plurality of linear pre-creases are formed in the inner side of a paper web. Additionally, the disclosure relates to a use of the side gusset paper container according to the disclosure as a compost collecting and/or carrying container and/or as a fillable container which is self-standing in the unfilled state.

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.

The thermal bag (2) is made of thermally insulating composite material folded to form a bottom and welded along lateral borders (3) to form a body (1) of the bag with a mouth (5) at the level of which a handle (7A, 7B) is applied. The composite material defines a bottom folded in an accordion-like fashion opposite the mouth of the bag, and a laminar stiffening element (15) of the accordion-like bottom is disposed inside 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.

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.

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.

A reuseable bag with handles is formed of a single sheet, folded to form two sides and a bottom, and includes only heat-seals formed using heat and pressure along side edges and width-wise across an upper portion of each side wall forming reinforced regions of the bag walls at which handle attachment points are disposed for attaching handles by heat-sealing using heat and pressure.
