In short, stand up bag is a pouch that can stand by itself without other support. Until the 1980s and 1990s, with the development of materials, design, and equipment, the application of bags increased. Today, standing bags have become the first choice for many well-known brands. The company uses these sealed bags for weed, coffee, tea, pet food, beauty product packaging, etc.
Basic Material Structures
The standing bag is made of multiple layers of barrier materials laminated together. The performance of packaging is related to the quality of barrier material and the structure of the bag. Therefore, choosing a higher-quality bag ultimately means fewer problems. There are usually 2-3 layers in the construction of a stand-up pouch, including the outer layer, middle layer, and inner layer. Each layer has different structures and provides a protective barrier to protect the contents from factors including oxidation, moisture, light, odor, or a combination of these.
