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 twist

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.

A plastic bag dispensing assembly from which large attached plastic bags are tensionally dispensed with minimized twisting, comprising: A. A coreless would roll of said attached plastic bags which are attached but separated by transverse lines of perforations, said roll having an outer diameter, an inner diameter, Di, and an inner circumference, pi, the length of said bags between said lines of perforations being at least equal to said circumference, whereby said minimizing of untwisting is imparted, said attached plastic bags beginning with an innermost bag and ending with an outermost bag, and said roll being flattened, whereby said inner diameter forms a line having a length calculated as pi/2, and horseshoe-folded along at least one fold line in parallel to said lines of perforations, whereby said minimizing of untwisting is preserved; and B. a dispensing carton within which said horseshoe-folded roll is stored, said carton having a dispensing opening through which said innermost bag is initially pulled by a user for dispensing thereof.
