Side gusset bags use expandable side folds to hold more volume in a slim profile, the classic format for coffee and bulk dry goods. Gerun Pack laminates foil and PET/PE for a strong barrier and a tidy brick shape that palletizes well. The gusset opens on filling, increasing capacity without widening the front face, so branding stays large and legible. One-way degassing valves, tin-ties, and zippers are standard options. Applications: roasted and ground coffee, tea, grains, pet food, and industrial powders. Preferred where volume is high but shelf footprint must stay narrow. Customization: 250 g to 5 kg, valve or tin-tie or zipper, matte/gloss, window, and full print. We tune the laminate to your product's oxygen and moisture limits. Why Gerun: established 2009, OEM/ODM, ISO 9001 and BRC, 30,000㎡ plant, low MOQ. Share weight and barrier need for a quote and sample.
