Flat bottom coffee bags packaging offering stable, quad-seal and gusset formats for coffee and other food, pharmaceutical, and electronic products. Custom rotogravure printing, premium finishes, and functional add-ons like zippers, degassing valves, and windows deliver strong shelf presence with WVTR/OTR barrier protection.


Pinch bottom bags have a flat seal formed by pinching the film at the base, creating a simpler seam with less standing stability. Block bottom (flat/quad-seal) bags use an additional bottom panel that folds out to create a wide, flat base, allowing the bag to stand upright on shelves for stronger retail presentation.
