REUSABLE SELF-OPENING T-SHIRT BAG APPARATUS AND METHODS OF MANUFACTURE THEREOF
A bag apparatus includes a first bag wall, sides, a bottom, and an opening. Handles extend from the opening a define slits for hanging on a dispenser. A tab is disposed between the handles and extends from the bag at the opening. The tab includes a slit for handing on a dispenser. The bag and tab are configured to permit opening of the bag with pulling with a first force when the bag is mounted on a rack, and separation of the bag at the tab with pulling with a second force stronger than the first force.
Flexible Package
Package having a flexible inner sheet, a flexible secondary inner sheet, a flexible secondary outer sheet, and an outer sheet. The inner sheet and secondary inner sheet are joined together at least an outer seam and forming one or more primary expansion chambers. The package also has a flexible secondary outer sheet and an outer sheet, joined together at least an outer seam and forming one or more secondary expansion chambers. The secondary outer sheet and the outer sheet also form one or more non-expansion chambers that can be a label surface.
Method of Making a Plastic Film with Integrated Zipper Closure, and Plastic Bag Having an Integrated Zipper Closure
A method of manipulating thermoplastic film to create integrated features and particularly relates to an improved method of manufacturing a packaging bag that is reclosable after initial opening. Multiple sections of thermoplastic film are layered on top of themselves to form a multi-layer portion of the thermoplastic film. The multi-layer portion may then be conglomerated into a unitary thicker portion of the film that can then be shaped into a closure strip. In order to form a bag, a second such closure strip may be made. The two closure strips are then aligned and the remaining open portions of the bag are then sealed such that the closure strips form a reclosable opening that may be opened and closed repeatedly.
SYSTEM AND PROCESS FOR MAKING A POUCH OR CONTAINER
A process for making a container includes the step of providing at least one of a slider, sticker, textured surface, pattern, or embossed surface along a folded web of thermoplastic material that comprises a plurality of container templates. The process also includes the step of picking up, with a turner, each container template. The turner includes one or more rotator assemblies that include a rotatable shaft and a bag-contacting surface connected to an end of the rotatable shaft. The bag-contacting surface is configured to engage a top exterior side of each container template. Additionally, the process includes the step of reorienting, with the turner, each container template. The rotatable shaft is configured to horizontally translate and rotate each container template.
Method of production of fabric bags or containers using heat fused seams
A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

Device for opening an end region of a tubular bag body
A device for opening an end region of a bag body, which end region extends between an open tube body end and a bottom central line, having a transporting device, on which the bag body is transportable with adjacent tube walls at a transport rate (V) in a transporting direction, and suction devices arranged on both sides of the bottom central line, which are driven so as to be moveable transversely back and forth to the transporting direction, wherein the suction devices are movable in addition in the transporting direction back and forth. The suction devices are mounted at first articulated joints, wherein at each first articulated joint there are hinged two pivoting arms pivoting relative to one other, wherein each pivoting arm is pivotingly connected to a positioning pivoting arm by means of a second articulated joint and wherein each positioning pivoting arm is movably driven.
System and process for making a pouch or container
A system and process for making a container or pouch that separates the cutting and sealing steps into two distinct steps with a separate step of rotating the container or pouch template 90 degrees relative to a direction of travel between the cutting and sealing steps.
REUSABLE BAG APPARATUS AND METHODS OF MANUFACTURE THEREOF
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.
Method of production of fabric bags or containers using heat fused seams
A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.
