Abstract

A bag made of flexible sheet material having an opening defined by a periphery. Juxtaposed with the periphery is a closure zone. The closure zone has induced extensibility in a direction perpendicular to the opening of the bag so that handle ties may be conveniently formed upon extension of the closure zone material. The handle ties are bound together to form an integral closure for the bag. The closure remains bound in response to forces upon it. The induced extensibility is provided by a network of dual regions having different modes of extensibility. The dual region network also provides the advantage of an increased gripping surface for forming the handle ties.
