发明名称 Liners or bags and method of making them
摘要 A method of forming a plurality of interconnected bulk bags or with an interconnecting section of material between adjacent bags on a roll or blank of flexible material to permit the blank of material to be advanced for subsequent processing. The interconnecting section is defined at least in part by a separation line that permits scrap or waste material to be removed from the blank without removing the interconnecting section. This permits the bags to remain interconnected after they are formed so that they may be disposed on a roll or folded in a box for convenient shipping and handling of a plurality of bags. Desirably, perforations maybe provided between adjacent bags to facilitate removal of an individual bag from the remainder.
