Stand up pouch bags have revolutionized product packaging. Unlike traditional packaging mediums – boxes and cartons – stand up pouches consume a lesser amount of resources. Also unlike old packaging methods, stand up pouches can be highly customized. An elementary knowledge of how these pouches are made can help businesses save money. Let’s look at the manufacturing process of stand up pouches.

 

A stand up pouch is essentially a laminated bag which is made from several layers of plastic film, aluminum foil, and other materials. As these pouches can be printed with virtually any logo, color, and design – they offer a huge potential for creative advertising.

 

The life of a stand up pouch begins when a set of plows passes through raw materials – usually plastic – to convert W-shape gussets into bottoms. Without these gussets, a stand up pouch cannot stand by itself. A zipper is sealed near the top edge of a pouch, if the pouch has it. Zippers are a common access method. Other access methods include spouts, re-closable openings, and perforations.

 

After the formation of the gusset, then is the turn of vertical seals. They constitute the side walls of a stand up pouch. These vertical seals are glued to the bottom gusset and the zipper. A vertical cut is made through one of the sides to place the container. Once the container is in place, the bag is shipped from where it is taken to a station that fills the pouch with the product. Then this pouch is grouped together with several other pouches, packaged in a larger carton, and then shipped to another station.

 

At the second manufacturing station, the zipper is closed. The pouch is sealed for the second time at this station. This sealing takes place above the zipper. A notch is cut between the top sealing and zipper – making it easier for users to open the package. Then the pouch is sent to its destination – which can be a small family owned retail shop or a large retail supermarket.

 

Stand up pouches offer an excellent way for food and liquid packaging. They can be used for a variety of food packaging including salt packaging, sugar packaging, cold drink packaging, pet food packaging, medicine packaging, and pre-cooked food packaging. They can also be used to package non-food items such as chemical products, cleaners, and garden materials. Stand up pouches provide a durable and inexpensive packaging option which is highly usable – a win-win situation for customers and manufacturers.
