This 5 1/8" x 8 1/8" black foil stand up pouch with a 3 1/8" bottom gusset is engineered to protect and showcase up to 4 oz of product in a sleek, retail-ready format. Constructed with a robust 5.4 Mil structure, it offers superior barrier protection against moisture, oxygen, and light—critical for preserving freshness, flavor, and aroma in food, nutraceutical, and specialty products. The stand-up design maximizes shelf presence while minimizing space, making it ideal for point-of-sale displays and efficient back-of-house storage. Designed with both product performance and operational efficiency in mind, this black foil stand up pouch runs smoothly on most manual and automated filling and sealing lines, helping maintain consistent packaging speeds. Its durable construction resists punctures and tears during handling and shipment, reducing waste and damage claims. The bold black foil exterior delivers a premium, high-contrast backdrop that helps labels, lot codes, and branding elements stand out for easy identification and compliance.
