Abstract: 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.

Abstract: A plurality of collapsible bags are integrally formed in a tubular blank of a flexible material with a perforated portion disposed between adjacent bags to facilitate separating them. When formed, adjacent bags are connected in end-to-end relationship and lie generally flat such that the elongate blank may be wrapped around itself forming a roll of the bags or the bags may be pleated or accordion folded flat within a container whereby they may be individually removed from the container for use. Handles are preferably integrally formed with each bag extending from adjacent the top wall of the bag. A spout is preferably also integrally formed with the bag to facilitate filling and emptying of the bag. The bags are particularly suited to contain liquids or frozen liquids and are preferably made of a food-grade plastic film material suitable to contain various foods or beverage products. The bags may each be received in a separate container to support a filled bag.
