BAG WITH EXTENSIBLE HANDLES

摘要

A bag (10) made of flexible sheet material having an opening (12) defined by a periphery (14). Juxtaposed with the periphery is a closure zone (26). The closure zone has induced extensibility in a direction (80) 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 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.
