摘要: A bag (10) made of flexible sheet material having an opening (12) defined by a periphery (14). Juxtaposed with the is closure zone (26). The has induced extensibility in direction (80) perpendicular to so that handle ties may be conveniently formed upon extension material. are bound together form integral for bag. provided network dual regions different modes extensibility. region also provides advantage increased gripping surface forming ties.
