Custom Printed Side Gusset Pouch with Valve 2lb 1kg Coffee Packaging Kraft Paper Quad Seal Bag

ZL-Pack Back-Seal Bags
Features a central back seal combined with side gussets (accordion folds)—also known as a central-seal gusseted coffee bag.
Common Materials: High-barrier laminates such as PET/VMPET/PE or PET/AL/PE.
Standard Optional Add-ons: One-way degassing valves and easy-tear notches; zippers are typically not included in this design.
The overall profile is slender, square, and structurally uniform.
The side gussets allow for expanded capacity, enabling the bag to hold a larger volume than a standard flat pouch of the same height; furthermore, it requires less material than an eight-side-seal bag, offering superior cost-effectiveness.
Featuring a continuous back seal combined with top and bottom seals, the design boasts a large heat-sealing surface area and a robust closure; this ensures durability during transit, preventing ruptures, air leakage, and moisture ingress.
With its slender body and stackable nature, the bag optimizes space utilization during packing, reduces logistics costs, and allows for neat, organized storage in warehouses.
Ideal for packaging 125g, 250g, 500g, and 1kg quantities of coffee beans, ground coffee, and roasted coffee products.
Characterized by its back seal and side gussets, this design offers a blend of simplicity, premium aesthetics, and high cost-efficiency, making it a widely adopted choice for factory mass production, retail store stocking, and international export trade.ZL-Pack Back-Seal Bags
