Disclosed is a bag that is produced continuously, forming a group of bags that occupy a minimum volume, the bags being individually detached from the group by means of precut lines, such that the bags are supported on dispensing means by means of upper and lateral sectors (10) delimited by precut lines (7), the tearing of which determines a handle (8) for the bag with the corresponding hole (9) thereof for inserting the fingers of a hand, the bag being separated from the lateral sectors (10). The bags have a bottom determined by three parallel folding lines that allow a W shape to be obtained, such that the bag is flat when not in use, incorporating a double-wall reinforcement at the level of the handle. The bag could optionally be produced using three bands, two end paper bands and a transparent intermediate band, fastened parallel to one another.

The present invention relates to a flexible pouch (1) having a wider opening (2) allowing to get a better access of the content of the pouch (1). The perimeter (a) of the opening (2) of the flexible pouch (1) is greater than the perimeter (b) of its bottom (3). At least one of the lateral folding lines (5) of the flexible pouch (1) comprises a welding line (6) of a width (w). A part or all of the lateral welding lines (6) of the flexible pouch (1) have a width (w) which is not constant along its length. The invention also relates to a kit-of-part comprising the flexible pouch (1) according to the invention and a container (14) adapted to receive said flexible pouch (1).

A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Cooperating heat-sealing jaws, including cooperating U-shaped sealing surfaces, act to integrate and seal each individual sleeve with the flexible web to form the bottom gusset of each package, with the heat-sealing jaws preferably configured to include cooperating top sealing surfaces for simultaneously forming a top seal in an adjacent one of the packages.

A tote package including a middle section that forms a bottom portion, a first side section connecting the first side section and the middle section, wherein the first side section creates a first side portion of the tote package that tapers upwardly from the bottom portion to a top portion of the tote package, and a second side section that is opposite of the that connecting the second side section and the middle section, wherein the second side section creates a second side portion of the tote package that tapers upwardly from the bottom portion to the top portion of the top portion of the tote package, a handle positioned on the top portion of the tote package, wherein the middle section, first side section, and second side section intersect to create a tapered front portion of the tote package that extends beyond the bottom portion.

The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the bag or the body of the bag comprises incrementally stretched polymeric film.

An example tote package is disclosed for carrying a load external to a UAV. The tote package may be generated by folding a sheet of material. The sheet may include a middle section, a first side section, and a second side section. When the sheet is folded, the middle section may create a bottom portion of the tote package. Additionally, the first side section may create a first side portion tapering up from the edge of the bottom portion to the middle of the top portion of the tote package. Furthermore, the second side section may create a second side portion tapering up from the opposite edge to the middle of the top portion. At the top portion, the first and second sections may connect to create a handle. The first side, second side, and middle sections may be folded to create front and back portions of the tote package.

A soft transfer case for biological and chemical material is provided. The transfer case includes a film-laminated, woven textile exterior layer as a pouch resembling an open cylinder. The cylinder is capable of being clamped at each end of the cylinder. A pouch shaped and single open end elastomeric bladder capable of containing biological and chemical material can be contained by the exterior layer. The bladder requires only one seam which is used to permanently seal the open end with the material contained therein. Upon pressurization of the bladder, the exterior layer expands and a restraining force is generated between the textile layer and the clamps.

A method of sorting a first subset of items in an order handling center, wherein at least a majority of the items of the first subset are sized below a predetermined size limit. The method includes directing the first subset of the items through an opening into a bag having a plurality of panels of flexible material coupled together at a plurality of seams. The method includes causing the bag to assume a substantially cuboid shape as the bag is filled to capacity with the first subset of items and stacking the bag on a pallet at a staging destination within the order handling center. The staging destination is associated with a delivery route from the order handling center.
