Side-gusseted bags are named for the gusset, or fold, on either side of the bag. The gussets expand when the package is filled with product, and the weight of the product usually holds the bag upright. This package format has two long faces, or panels, on the front and the back for product branding as well as the option to include a degassing valve. Side-gusset coffee bags are a popular and reliable way to package coffee beans while keeping the product fresh until opened by a customer. They are also widely used in other markets such as pet food, powdered goods, teas, and other specialty food products.
