Our custom flat bottom coffee packaging bags combine shelf-friendly design & premium freshness protection: the stable flat bottom stands steadily for retail display, while food-grade aluminum foil blocks 99% of oxygen/moisture. Backed by Foshan Ruihong’s 8-year factory (80-100M RMB annual sales) & 8-side seal machine, we deliver high-quality, brand-aligned flat bottom pouches tailored to your coffee line.
