Center-seal pouches, also known as center-sealed pouches, are a type of flexible packaging commonly used for packaging various products like snacks, grains, powders, and liquids. The pouch is created by folding a single sheet of material in half and sealing the edges on both sides, leaving the center portion open for filling the product. This center seal provides a clean, symmetrical appearance to the pouch and ensures that the contents are securely enclosed.
