Often there are many different combinations of materials or film constructions that will meet the minimum performance requirements of an application. In these cases selection of the final packaging structure may be based on considerations such as availability from multiple suppliers and ability to provide differentiation over competitive packaging. For example a combination of a box and an inner liner may be used or a stand-up pouch may be used, each combination providing the minimum requirements for product protection and safety. One manufacturer may select to use a box and inner liner and other manufacturers may elect to package their product in a stand-up pouch for the same product. Or one manufacturer may choose to use a stand-up pouch and another manufacturer may choose to use a pillow pouch for the same product.
