Also known as a corner seal or W fold, this style of stand up pouch is made from just one piece of film so there is no seal at the gusset, making it especially popular with manufacturers of granular products like sugar or salt. In this style of stand up pouch, the product housed in the package sits directly on the shelf. It is ideal for products weighing 5 pounds on up…however not all manufacturers can make this style of bottom gusset.
