A package for storing or containing at least one ethylene response manipulation agent such as 1-methylcyclopropene is disclosed. The package can have multiple film layers, but preferably the outer layer comprises a polymer at least partially soluble when contacted with an aqueous media, and the inner layer comprising an ethylene response manipulation agent permeable film structure. Aerosols comprising the ethylene response manipulation agents are also disclosed.

A 3-D flexible bag to be filled with a biopharmaceutical product is formed by assembling of two wall elements and two gussets. At least one connection port is provided, for filling and/or emptying. A substantially parallelepipedal configuration is obtained in a filled state thanks to the unfolding of the gussets combined with the folding of flaps of the two wall elements. A transverse weld, formed at one end, connects the two wall elements of the bag and extends continuously, keeping in a folded-flat state:—an elongate edge portion of one gusset;—an elongate edge portion of the other gusset. This transverse weld has a length corresponding to a determined dimension of the flexible bag in the parallelepipedal configuration.

A method (100) of making an integrated handle (304) on at least one side gusset (308) of a flexible package (300) is provided. The method (100) includes steps of sealing a handle patch (222) on at least one half width of the side gusset laminate (218). Further, the method (100) provides parallel openings on the handle patch (222) such that a centre line of the two parallel openings coincides with centre lines of each half of the side gusset laminate (218). A cover patch (226) is sealed over the handle patch (222) overlapping the edges of the handle patch (222) and simultaneously with the side gusset laminate (218) all around, such that a predefined area is left unsealed between the two parallel openings. The longitudinal edges of the side gusset laminate (218) are folded such that the handle patch (222) comes on the outer surface of the continuous open tube (242) being formed. The continuous open tube (242) is thereby used for manufacturing the flexible package (300).

A bag includes a bag body defining a housing space, an elongated member provided on a first face portion of two face portions forming the bag body, and a tab. The elongated member includes an elongated tearing guide piece, a belt-shaped base provided between a second face portion and the tearing guide piece along a longitudinal direction of the tearing guide piece. The tab has an outer edge defined in the first face portion by a cutting line penetrating through the belt-shaped base and the first face portion. A protector covering the tab is provided on a side of the first face portion provided with the belt-shaped base.

In a plastic bag including a triangular flap which has a folded hypotenuse and an open hypotenuse, a flow path is formed by the folded hypotenuse or the open hypotenuse to discharge air or gas through the flow path.

A plastic bag has a safety even when a flap is not adhered on an outer surface of a side gusset. One of the opposite end portions of the side gusset is obliquely folded in half along a fold line and interposed between the two layers of the side gusset, so that the flap is formed by the end portion between the two layers of the side gusset. The flap includes a folded edge formed by a folded inner edge of the side gusset, and an open edge formed by one of the opposite end edges of the side gusset. The flap further includes a joining edge extending straight or curved and joining the folded edge and the open edge on opposite sides of the fold line.

The present invention relates to a method for making packages (100) made of flexible material. The method comprises a first step which consists in providing a first strip (19) and a second strip (20) made of flexible material, positioned on top of each other along a conveying direction and preferably having the same width. Moreover, the method comprises a second step of securing the first strip (19) to the second strip (20) by means of a welding surface (24) which extends in a direction perpendicular to the conveying direction of the first and the second strip (19, 20) for a first length (h4) which is less than the width (h3) of each of the first and the second strip (19, 20); wherein the welding surface (24) is positioned at a first side edge (39) of the first and the second strip (19, 20). In addition, the present invention also comprises a machine (200) which allows using such method.

The present invention relates to a method for forming packages of flexible material with a first side gusset and a second side gusset starting from a strip coming from a reel having a sliding direction. The method comprises the following steps: making the first gusset by folding close to a first side edge of the strip coming from the reel, and making the second gusset by folding the strip coming from the reel; in which the step of making the second gusset is performed on a portion of the strip which extends in the sliding direction after the step of making the first gusset was performed on the portion of the strip. Moreover, the present invention relates to a machine configured so as to carry out the method.

A plastics shipping bag includes a closure flap which projects beyond the front wall, can be folded over the outer face of the front wall, and comprises a passage opening, which is configured and designed for the passage of a handle loop or handle of the front wall and/or rear wall, wherein the closure flap comprises at least one fastening means between the opening edge of the rear wall and the passage opening, which fastening means is configured and designed to close the opening end once the closure flap has been folded over onto the outer face of the front wall. The plastics shipping bag can be used for shipping foods, such as chilled foods.

A package is provided that is formed from a packaging material, such as film, having increased adhesive in critical locations, such as adjacent folds in the end seal and other areas so that that the increased adhesive can at least partially fill voids adjacent such folds. The additional, localized sealant material is applied in a plurality of discrete locations in the end seal or other region adjacent where folds are formed and overlap with a sealant layer so as to provide additional sealant material for at least partially filling the voids without being present throughout the entirety, majority or large portions of the packaging material.
