Abstract:
A bag has a reinforcement that is configured in a predetermined manner for reinforcing at least a portion of the bag. One or more predetermined areas of the bag may be reinforced. The bag may have one or more layers, and may be reinforced by placing and affixing reinforcing media in selected areas. The nature of the reinforcing media—its dimensions and structural properties—may be selected with respect to targeted uses of the bag. The bag may be subjected to one or more types of potentially failure-causing strain (e.g. bending, twisting, puncture, tensile, compression) during the useful life of the bag. For example, the bag may be stressed during filling the bag with product, top sealing, conveying by hand or machine, loading and stacking, transportation, storage, selling and final use by the consumer.
