This 6 3/4" x 11 1/4" 4.8 Mil black foil stand up pouch with a 3 1/2" bottom gusset is engineered for premium retail and wholesale packaging of 16 oz products. The high-barrier metallized construction helps protect contents from oxygen, moisture, light, and external odors, extending shelf life and preserving flavor and aroma. The black foil finish creates a clean, upscale appearance that enhances brand perception on the shelf or online, making it ideal for coffee, tea, specialty foods, nutraceuticals, and dry product refills. Equipped with an integrated one-way degassing valve, this 16 oz metallized stand up pouch is particularly well suited for freshly roasted coffee and other off-gassing products. The valve allows trapped gases to escape while blocking oxygen from entering, preventing package swelling and protecting product quality without manual burping or secondary vents. The reliable 4.8 Mil thickness provides strength and puncture resistance to stand up to handling and shipping, while the 3 1/2" bottom gusset enables the pouch to stand securely on retail shelves and in display fixtures.
