Custom Aluminium Foil Gusset Bag

Custom aluminum foil gusset bags use a metalized or pure foil middle layer to deliver the highest level of barrier protection available in a gusset bag format — blocking light, oxygen, and moisture almost completely. Where a standard laminated gusset bag offers good protection, foil gusset bags are the choice when shelf life and product stability matter more than transparency, and where the fill item is light-sensitive, aroma-sensitive, or needs long-term storage stability. Available in side gusset/ bottom gusset/ block bottom gusset construction, with full-color custom printing across all panels — the opaque foil surface takes matte, gloss, and metallic finishes particularly well. Commonly used for freeze-dried food, specialty coffee, supplements, and any product where oxidation or light exposure directly shortens shelf life. Custom sizes available alongside our standard range, with zipper, tear notch, and heat seal closure options. Lead time 7–15 business days.
