Custom Block Bottom Gusset Bag

Custom block bottom gusset bags — also called flat bottom gusset bags — combine a rigid rectangular base with side gusset panels, giving the bag a box-like structure that holds its shape under heavier fill weights. This is a step beyond a standard bottom gusset bag: the block-formed base distributes weight more evenly, making it the preferred format for bulkier or denser fill items where a simple flat base isn't rigid enough. Available in high-barrier laminated structures, compostable, and recyclable materials, with full-color custom printing across all panels. Commonly used for pet food, bulk snacks, industrial powders, and other higher-weight fill applications where structural stability during handling and stacking matters. Custom sizes available alongside our standard range, with zipper, tear notch, and heat seal closure options. Lead time 7–15 business days.
