Stand up bag refers to a flexible packing bag with a horizontal support structure at the bottom, which does not rely on any support and can stand by itself whether the bag is opened or not.
And there are 3 types of the standing bottom
The round bottom stand-up pouch has a round bottom; the border of the gusset is welded at the sides strengthening the pouch’s overall structure and guarantees an easy and beautiful upright stand. It is ideal for light weight product (under the 600 gram).
The K seal bottom has a sealing at a 30-degree angles from the bag. The angle allows to release some stress off the seals (it prevents falling) and it allows an additional volume.
The normal bottom stand-up (also known as the corner seal) is a stand-up pouch made from just one piece of film so there is no seal at the gusset. It is commonly used as stand-up pouch for granular products like sugar.
Stand up bag is a relatively new packaging form, in upgrading the product grade, enhance the visual effect of shelves, portable, easy to use, fresh and sealing and many other aspects of the advantages.
