Short Description:

Side gusset bags are named for the gusset, or fold, on either side of the bag. The gussets expand when the package is filled with product, while the weight of the contents holds the bag upright. At Union Packing, we make a full line of side gusset bags to accommodate most coffee roasts, as well as products sensitive to water vapor and oxygen. Union Packing foil side gusseted bags come with or without our one-way degassing valves. Many of our side gusset bag options feature “easy-peel” film for customer convenience.
