ABSTRACT
Perhaps the oldest form of packaging and one that is still growing in use with renewed popularity, is the bag. It performs all the basic functions of packaging-containment, protection, and communication-generally at the lowest possible cost. It is created in a wider range of sizes and materials than any other packaging form. It is used for virtually every type of product from liquids and powders to solids and, therefore, offers a versatility unmatched by any other type of product container.
