Stand up pouches do, in fact, stand up because of their design and the materials used to build them. Yes, a stand up pouch isn't made so much as it's built. Multiple layers of scientifically-formulated (and, if necessary, food grade film) are laminated together to create a barrier pouch ideal for virtually all types of retail product packaging.
These pouches protect contents from vapor, odor, moisture, light, air and/or pests, depending on what the specific product requires. For food items and other products with "best by" dates, stand up pouch retail product packaging will help extend your shelf life. For liquids, stand up pouches can be ordered with a pour spout/resealable cap combination that not only preserves freshness but prevents leaks and spills. A zip lock closure system performs the same functions for non-liquid products.
After product quality and price, convenience is perhaps the most important feature to consumers and stand up pouches deliver. Strong, stable and puncture-resistant, stand up pouches are flexible enough to store almost anywhere there's room. By standing up, they store conveniently in the garage, closet, refrigerator/freezer, RV pantry, kitchen cupboard, laundry room, even the trunk of a car. Of course, both the zip lock closures and spout/cap combinations are easy to use.
Another function of retail product packaging is selling your brand. Stand up pouches do that
