ABSTRACT:
A method for minimizing twist in large plastic bags to be center-dispensed from a wound coreless roll of sequentially attached plastic bags. The roll is flattened or collapsed and folded at least once into a U, C, S, M, W, or accordion shape. The method is particularly effective for minimizing twisting of center-dispensed bags when the bags are at least as long as the inner core circumference. The method is also useful for imparting selected dimensions to the horseshoe folded roll that enable the roll to be inserted into a dispensing carton having dimensions preferred by users of the bags, such as cartons having square ends.
