DRAW TAPE BAG
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.
Plastic Bag Making Apparatus
In order to provide an apparatus for successively making plastic bags each of which includes panel portions and a bottom gusset portion, in a way different from the prior art, upper and lower webs of panel material are superposed on each other and fed longitudinally thereof. A web of bottom gusset material is supplied to one of the webs of panel material to be superposed on the outer surface thereof, the web of bottom gusset material having opposite side edges one of which extends along ones of the opposite side edges of the webs of panel material. The web of bottom gusset material and the other web of panel material are temporarily fixed to each other at ones of the opposite side edges thereof after the webs of panel material are superposed and the web of bottom gusset material is supplied. One of the webs or the other web of panel material and the web of bottom gusset material are then guided so that one of the webs or the other web of panel material can be folded at a position adjacent to ones of the opposite side edges of the webs of panel material when the webs of panel material are fed. The web of bottom gusset material is combined with the webs of panel material. The panel portions are formed by the webs of panel material while the bottom gusset portion is formed by the web of bottom gusset material.

METHOD OF MAKING PACKAGES HAVING RE-CLOSABLE ZIPPER ON ONE PANEL AND PACKAGE THEREOF
The present invention provides a method of making re-closable package (10) and a product made therefrom. The said method comprises providing a first web (46) and a second web (50), folding a predetermined portion (P) of the first web (46) into a V-shape (58) thereby forming an extended portion and cutting the V-shape (58) of the first web (46) to form a pair of extended panels (62). A re-closable zipper (42) sealed with the extended panels (62). The first web (46) sealed with the second web (50) at a first sealing zone (SZ1) and second sealing zone (SZ2). Subsequently, cut the first web (46) and the second web (50) at the first sealing zone (SZ1) thereby obtaining a re-closable package (10). The said re-closable package (10) comprising a first panel (14), a second panel (18) and optionally side gussets (22, 26) and a bottom gusset (30).
A RECLOSABLE FLEXIBLE POUCH AND METHOD AND APPARATUS FOR MANUFACTURING RECLOSABLE FLEXIBLE POUCHES
A reclosable flexible pouch having first and second interlockable closure formations integrally formed in two longitudinal side portions of a continuous flexible sheet.

The web of bottom gusset material is combined with the webs of panel material. The panel portions are formed by the webs of panel material while the bottom gusset portion is formed by the web of bottom gusset material.
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.
ZIPPER TAPE-EQUIPPED BAG BODY, ARTICLE HOUSING METHOD FOR ZIPPER TAPE-EQUIPPED BAG BODY, MANUFACTURING METHOD FOR ZIPPER TAPE-EQUIPPED BAG BODY, AND MANUFACTURING DEVICE FOR ZIPPER TAPE-EQUIPPED BAG BODY
A female belt-shaped base is attached to a bag body at a region from a female hook to a first end near an open end of the bag body and to a second end near a housing space. A male belt-shaped base is attached to the bag body only in a bonding region without being attached at a region from a position where an engagement portion is continuously attached to a first end near the open end of the bag body.
STACK FORMED OF BAGS
The invention relates to a method for producing at least one stack (9) formed of bags (1), comprising the following steps: feeding tubular or semitubular material in order to form a bottom material layer (s) and a top material layer (3), introducing at least one weld seam (4) in order to connect the bottom material layer (2) and the top material layer (3) in order to form individual, but still connected bags (1), introducing a formatting fold (8) into the layer web, formed of still connected bags (1), separating the bags (1) connected in the formatted layer web into individual bags (1), wherein said bags (1) still have the formatting field (8), forming a packet of individual bags (1) into a stack (9) having a defined number of bags (1), and introducing at least one fold into the stack (9). The invention further relates to a bag (1), a stack (9), and a dispensing box (12).
