The Stand-up pouch Production Process

Posted by Kuajing Plus on January 28th, 2021

Today's producers are raving about the benefits of the stand-up pouch, as they have really changed how products can be shown and merchandised at retail. They use much less material than other traditional packaging techniques like containers or boxes and can be completely customized to fit any requirement. However understanding why flexible packaging can be so beneficial to your company in fact requires 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 bear in mind about the stand-up pouch is that they are a laminated film bag, generally made from plastics or a mix of plastic movie and aluminum foil. They can be printed with any color, logo design, or style, so the prospective to truly make an impact on retail racks is incredibly high.

Made from a constant web of product, the initial step in the stand-up pouch manufacturing procedure takes place when the product is traveled 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 referred to as zip locks, are the most accessible to the technique, however, spouts, perforations, and other recloseable openings are also used.

When the gusset is formed, vertical seals are then made along the pouch's sides, and the zipper is pressed into the exact 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 end product or packaged in cartons for delivery to the end-user.

After the item is dispensed into the pouch, it takes a trip to another manufacturing station where the zipper is closed and the pouch is sealed once again, above the zipper. A notch is typically cut into the sides of the pouch in between the top seal and the zipper, so it is easy for end-users to open.

Stand pouches are extraordinary options for both dry food packaging and liquid products, such as pet food, liquid house cleaners, personal care items, chemical products, and granular products like salt or sugar. When overall, the stand-up pouch is very resilient and user-friendly-- both for customers and for your earnings!
