Today’s manufacturers are raving about the advantages of stand-up pouch, as they have actually revolutionized how products can be shown and merchandised at retail. They use much less material than other conventional packaging methods like containers or boxes and can be completely customized to fit any need. However understanding why flexible packaging can be so beneficial to your business actually needs an understanding of how they are made, as they can be made much cheaper and more efficiently than you’d believe.
The first thing to remember about stand-up pouch is that they are a laminated film bag, normally made from plastics or a mix of plastic film and aluminum foil. They can be printed with any color, logo, or design, so the prospective to really make an impact on retail racks is extremely high.
Made from a continuous web of material, the initial step in the stand-up pouch manufacturing procedure happens when the material is passed through a set of rakes that fold a W-shape gusset into the bottom so it can stand. If a zipper is to be part of the package, it is sealed on the inside faces of the web near the leading edge. Zippers, also known as zip locks, are the most access to the method, but spouts, perforations, and other recloseable openings are also offered.
When the gusset is formed, vertical seals are then made along the pouch’s sides, and the zipper is pushed into the same area to seal its ends and lower its density. The bottom folds of the pouch are then sealed, as are seals that hold the gusset together at the ends. The pouch is then cut apart vertically through the center of the side seals to develop the container part of the bag, and it is then reached the station that will fill the pouch with the final product or packaged in cartons for shipment to the end-user.
After the item is dispensed into the pouch, it travels to another manufacturing station where the zipper is closed and the pouch is sealed once again, above the zipper. A notch is normally cut into the sides of the pouch between the top seal and the zipper, so it is easy for end-users to open.
Stand up pouches are exceptional choices for both dry food packaging and liquid items, such as pet food, liquid home cleaners, personal care items, chemical items, and granular products like salt or sugar. When total, the stand-up pouch is very durable and user-friendly – both for consumers and for your profits!
