Flexible containers having improved seam and methods of making the same
A non-durable flexible container can include a first film wall including a first portion comprising at least one first structural support member defined in the first film wall, and a second portion that is free of a structural support member. The container can further include a second film wall including at least one second structural support member defined in the second film wall, wherein at least a portion of the first structural support member is adjacent to at least a portion of the second structural support member to define a seam region, and a side of the seam region defines an edge of the non-durable flexible container. The container can also include a closed produce volume defined between first and second film walls; and a seam projecting outwardly from the seam region at an intersection of the first and second film walls.

Method and machine for making flexible packages with side gussets
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.
ZIPPER TAPE, BAG PROVIDED WITH ZIPPER TAPE, AND METHOD FOR MANUFACTURING BAG PROVIDED WITH ZIPPER TAPE
There is provided a zipper tape bonded to a bag body having a first surface and a second surface and including: a zipper tape body including a first base strip bonded to the first surface, a second base strip bonded to the first surface with a bonding portion, and engagement portions being mutually engageable and projecting from the first and second base strips, respectively; and a cutting strip provided in a region where the second base strip faces the first surface and does not face the first base strip. The zipper tape body is formed of a resin composition whose main component is a polyolefin resin. The cutting strip is formed of a resin composition whose main component is a polyolefin resin and includes a cutting strip body and a peelable layer layered on the cutting strip body and formed of a resin composition having peelability to a polyolefin resin.
POLYMERIC BAGS AND METHOD TO MAKE SAME
The present invention is directed to a bag of polymeric film and a method to make the bag. The bag can be comprised of a front panel and a rear panel. The front and rear panels can each be comprised of multiple layers of film. The bag can be formed from a collapsed bubble of polymeric film that has been folded in half so that opposing edges of the collapsed bubble form an opening of the bag. One of the layers of the folded bubble can be split adjacent to an edge of the collapsed bubble and a draw tape film can be inserted between the layers of the folded and collapsed bubble. The collapsed bubble can further be embossed by a pattern that can provide enhanced properties to bags formed from the folded bubble.
TAPE, ZIPPER TAPE, AND CONTAINER WITH TAPE AND METHOD FOR MANUFACTURE THEREFOR
A tape includes, in a cross-sectional shape: a first and a second portion which are configured to be at least partially in opposition. The first portion includes: thick portions provided in corresponding one of a first and a third region, out of the first, a second, and the third region in a width direction of the tape; a first and a second thin portion provided at respective both end portions, in the width direction, of the second region positioned between the first and the third region; and at least one intermediate portion provided between the first and the second thin portion. The second portion includes: thick portions provided in corresponding one of the first and the third region and extending beyond end portions, in the width direction, of the second region; and at least one third thin portion provided in the second region and opposed to the intermediate portion.
PACKAGING FOR PRODUCTS AND MACHINE FOR MANUFACTURING SUCH PACKAGING
The packaging for products comprises a string of containers (1), each container (1) comprising a closure element (3).
The machine for manufacturing said packaging comprises an opener (6) for forming a space to be filled with a product; a dosing nozzle (8) for dosing the product into said space; a feeder (5) of closure elements (3); welding jaws (9) for welding the closure element (3) and edges defining a container (1) on the packaging; and a cutting unit (11) for separating the containers (1) from the packaging, forming a string of containers (1).
A new type of packaging is achieved, which combines the advantages of an envelope-type packaging with packaging with a closure element and, in addition, allows to be sold in the form of a string.
Method and system for manufacturing bags
A system and method of manufacturing reinforced bags having reinforcing elements applied about the bags to support the bags in an opened and/or upstanding configuration. A web of bag material can be fed from a supply and can be folded and secured to form the bags. A series of reinforcing strips can be fed through an adhesive application station for application of an adhesive material thereto in a desired pattern. The reinforcing strips and bags are brought into registration and are adhesively attached to form the reinforced bags.
POUCH CONTAINER AND METHOD OF MANUFACTURING THE SAME
A pouch container has a gas filling space therein, and includes a first wall section and a second wall section. The first wall section includes a first tongue-shaped portion. The second wall section includes a second tongue-shaped portion and overlapping the first tongue-shaped portion. A projection length of the second tongue-shaped portion is longer than that of the first tongue-shaped portion. A gas injection portion is provided in which an injection port communicating with the gas filling space is formed by joining both end portions of both the first tongue-shaped portion and the second tongue-shaped portion in a width direction, and the injection port is defined by a tip end portion of the first tongue-shaped portion in a projection direction and the second tongue-shaped portion at a portion facing the tip end portion.
