This 5 1/8" x 8 1/8" + 3 1/8" white paper stand up pouch is engineered to showcase and protect 4 oz of coffee, tea, snacks, or dry food products in a professional, retail-ready format. Constructed with a durable 5.4 Mil laminated structure, it combines a premium white paper exterior with a high-barrier interior film to help protect against moisture, oxygen, and odor transfer. The clean white paper finish supports high-end branding and labeling, making it ideal for specialty roasters, gourmet food producers, and private label programs that require a consistent, upscale appearance on the shelf. This 4 oz stand up pouch features a convenient 1-way degassing valve that allows trapped gases—particularly from freshly roasted coffee—to escape without allowing outside air back into the package. That degassing performance helps maintain flavor, aroma, and product integrity while preventing pouch swelling or rupture in distribution and retail environments.
