Pouch bags have become the standard packaging medium for many products during the past few years. They have taken the world of packaging by storm. They come with accessories that include zip seals, tear notches, spouts, and transparent windows. They can be made from plastic or a mix of metal (aluminum) and plastic. These bags offer a huge opportunity to brand and merchandise your product.
Stand up pouch bags come in many shapes and sizes. There are basically three factors that determine their size - height, width, and the bottom gusset. The third factor (bottom gusset) is an extra piece of material added at the bottom of a bag. It is expandable. Consequently it allows a plastic bag to carry more of a product. The bottom gusset can be made as large or as small (within a certain range) as the product requirements demand. Depending on the needs of a product, a manufacturer can choose between three popular bottom gussets:
(a) Round bottom gusset
(b) K-seal bottom gusset
(c) Plow bottom gusset
The exact size and type of gusset that is right for your business depends on the product characteristics. As a seller, we assume that you are already familiar with your product. This post will acquaint you with the three popular types of bottom gussets and what each of them can do. This information will help you take an educated decision. You can check the resources on our website for more information.
Round bottom gusset for lightweight and fluffy products
The round bottom gusset is ideal for products that weigh less than a pound. This gusset is the most common in the industry. It is made by welding the edges of the gusset to the supporting walls of the bag. This structure provides the pouch the strength it needs to stay in a vertical position.
K-seal bottom gusset for mid-weight products
K-seal bottom gussets are commonly used for products whose weight exceeds a certain limit. This kind of gusset allows extra volume in a pouch. Another feature of the K-seal bottom gusset is that it is designed to take the stress off the walls of a stand up bag. The gusset is sealed at a 30-degree angle from the bag.
Plow bottom gusset for heavier and granular products
This one is a seal-less gusset. It is especially popular among sellers of granular products - salt, sugar, tea, and coffee. The plow bottom gusset is usually employed to package products that weigh more than a pound.
