In one aspect, an insulation product may include a first layer and a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product. A take up factor of the first continuous paper sheet to the first layer may be greater than 1:1.

An apparatus successively makes plastic bags each of which includes an end surface provided with a protrusion, without specially supplying a web of bottom gusset material. A first web of panel material is folded along a first folded line at a position adjacent to a side edge of the first web, while a second web of panel material is folded along a second folded line at a position adjacent to a corresponding side edge of the second web. A first folded portion is formed in the first web. There exists a distance between the side edge and the first folded line, which is larger than twice a distance between the corresponding side edge and the second folded line by a predetermined distance, after being folded. The end surface is formed by the first folded portion, the protrusion being formed by the predetermined distance.

The present invention relates to a method for making airtight packages (100) made of flexible material that are configured to seal an environment inside the package with respect to an external environment, said packages (100) comprising a front panel (1), a back panel (2) and two side gussets (3, 4) provided at opposite ends of the front panel (1) and of the back panel (2) so as to connect the front panel (1) to the back panel (2). The method comprises a first step of folding a sheet (60) made of flexible material along two first fold lines (L1) which are mutually parallel so as to form a tubular element (61). Moreover, the method comprises a second step that consists in folding an end portion of the tubular element (61) along two second fold lines (L2) that are oblique with respect to the direction of the first fold lines (L1) so as to form an end portion of the tubular element (61) that has two triangular portions (6, 7) having two mutually parallel sides (8, 9) and having a distance between each other equal to twice a first predetermined distance (D1). In addition, the present invention also comprises a machine (200) which allows using such method and a package that can be made by means of such method and such machine.

A head seal device of a bag making apparatus includes a pair of seal units configured to face each other in a facing direction. Each of the seal units includes a heat seal member and a heater. The heat seal device includes an adjustment unit configured to move the first seal unit in a width direction of continuous sheet panels, and to move the second seal unit in the width direction of the sheet panels in accordance with movement of the first seal unit in the width direction.

An environmentally-friendly alternative to polyethylene garment and other product packages is made of paper, which can be recycled, re-pulped or composted. Each such package includes two parallel coextensive elongated sheets of paper joined together along their respective side edges and along a top edge by heat seal or an adhesive. The two sheets of paper define an expandable volume therebetween. Central portions of the two sheets of paper are separable from each other to increase the volume to accept an article of clothing or other product. Rolls of paper-based product protection material may be manufactured, from which individual packages may be made or cut. Methods and apparatus for manufacturing the product protection material are disclosed.

A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.

A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

An article of manufacture that has at least three layers of sealable material. There is at least one first seal between at least two of the layers in a first area having a first sealing affinity effected at a first sealing parameter. There is also at least one second seal between at least two more layers, where at least one of these two layers is distinct from the at least two layers joined by the first seal, in a second area having a second sealing affinity effected at a second sealing parameter, where the second sealing parameter is different than the first sealing parameter, thereby allowing for sealing of discrete areas of the article in discrete steps.

A method for manufacturing an intermediate material for a soft packaging container according to the present invention includes: a first overlaying step P1 of laying a second raw film sheet 120 over a first raw film sheet 110; a confining portion forming step P2 of forming a filler confining portion 50 for confining a filler 59, the filler confining portion 50 being constituted by a non-joined region between the first raw film sheet 110 and the second raw sheet 12, by joining a portion of the first raw film sheet 110 and a portion of the second sheet 12 to each other; a folding step P4 of folding the first raw film sheet 110 and the second sheet 12 with the first raw film sheet 110 on an outer side, such that the filler confining portion 50 is present in a state where an inner portion thereof is continuous on two sides that are connected via at least one folding position; an accommodating portion forming step P5 of forming an accommodating portion 60 by joining a plurality of portions including at least one of the first raw film sheet 110 and the second sheet 12; and a cutting step P6 of forming an intermediate material A1 for a soft packaging container by cutting at least the first raw film sheet 110. This configuration makes it possible to more readily and reliably manufacture a soft packaging container that has a filler confining portion in more regions.
