The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape has at least one stretched elastomeric strip attached to the draw tape in an extended condition. The draw tape may be smaller in size than the bag sidewalls. The draw tape may include an elastic characteristic, such as patterned ribs. In one embodiment, the roll of bag is kept under tension to maintain the elastomeric strips in a stretched condition.

A method for converting a web of preformed pouches to on-demand inflatable packaging. The method may include moving the web along a path of travel, attaching an outer skin to the outside of the web, and packaging the web into a non-inflated and stored configuration. The method may also include moving the web along a path of travel, depositing at least one product into each of a plurality of the preformed pouches, and inflating each of the preformed pouches to form a cushioning material.

This invention relates to a paper bag for bulk material such as cement, gypsum, granular material, animal feed or the like, with a bottom and with an upper part opposite the bottom, wherein bottom and/or upper part are folded and glued by closing up the side parts around side fold lines, in particular in the form of a cross or block bottom, wherein for gluing the side parts at least one gluing or bonding agent activatable after the application is provided, which is applied continuously at least from a side fold line up to at least the opposite side fold line of the side parts.

A method of forming reinforced packages. The method can comprise forming an attached web by adhering a blank to a web of material and moving the attached web in a downstream direction through at least a tube forming assembly and a carton forming assembly. The method also can comprise at least partially forming a tube by folding at least a portion of the web of material as the attached web moves through the tube forming assembly, forming a reinforcement sleeve by folding at least a portion of the blank so that the reinforcement sleeve extends at least partially around the tube as the attached web moves through the carton forming assembly, and forming a reinforced package comprising the reinforcement sleeve and a tube portion by separating the tube portion from a remainder of the tube, the reinforcement sleeve being adhered to the tube portion.

A vent for a package includes a multilayer laminate film comprising a vent having a first breach, a second breach, and a laser-formed channel extending therebetween, and the length and cross-sectional area of the laser-formed channel are configured to exhaust CO.sub.2 at a rate greater than a counter-flow diffusion rate for oxygen or water vapor.

A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.

A flexible pouch for receiving flowable products that includes a fitment having a spout to allow the flowable products to be discharged from the pouch. The flexible pouch is formed from a top and a bottom web of material. A sealant strip is attached to a top edge of each of the top and bottom webs of material. A fitment having a canoe and spout is positioned such that the canoe is positioned between the first and second sealant strips. The height of the canoe and the width of the first and second sealing strips are the same to minimize the amount of sealant material. The first and second sealant strips are sealed to each other along the entire width of the flexible pouch to entrap the canoe of the fitment between the top and bottom webs.

An apparatus is improved to successively make plastic bags each of which includes an end surface provided with a spout, by employing the general feeding way of panel material, to be simple in structure, low in cost, high in speed and to make it possible to successively make the plastic bags two by two. A first folded portion is formed in a first web of panel material 1. An aperture is formed in a second web of panel material 2. A spout is inserted into the aperture, the spout and the second web of panel material 2 being heat sealed with each other. The second web of panel material 2 is guided by a guide device 18 to be folded after being heat sealed so that a second folded portion should be formed in the second web of panel material. The spout is turned over by the second folded portion. The second folded portion and the first folded portion are heat sealed with each other while the second folded portion and the second web of panel material 2 are heat sealed with each other about the spout.

A flexible side-gusseted package and methods of making the same are disclosed. The package has a central longitudinal axis, a front panel, a back panel, and a pair of gusseted side panels. The front panel is secured to the gusseted side panels along a pair of side seal lines. The back panel is secured to the gusseted side panels along a pair of side seal lines. Each of the seal lines includes a pair of end portions and an intermediate portion. The intermediate portion, e.g., a concave recessed portion, of each side seal line is located closer to the central longitudinal axis than the end portions of the side seal lines to provide a package which is somewhat necked-down at its middle, to facilitate grasping of the package by users.

The invention comprises, in an embodiment, a resealable packaging structure comprising a container having a bottom and at least one sidewall extending upwardly therefrom, wherein the sidewall terminates in a flange. A flexible resealable lid is sealed to the flange. The lid comprises a polyethylene terephthalate layer disposed adjacent the flange, a pressure sensitive adhesive layer disposed adjacent the polyethylene terephthalate layer, and an oriented polypropylene layer disposed adjacent the pressure sensitive adhesive layer. The polyethylene terephthalate layer comprises a laser scored line which penetrates through the thickness of the inner layer but not through the outer layer and defines an opening portion that can be lifted out of the plane of the inner layer, thereby creating an opening through the lid defined by the laser score line.
