摘要： A web of preformed bags includes an exterior sheet material and an expandable slit sheet material. The exterior sheet material and an expandable slit sheet material are coupled along longitudinal seams. The expandable slit sheet material has slits arranged substantially parallel to the longitudinal seams. The web has a longitudinal fold such that the expandable slit sheet material is on the inner side of the exterior sheet material. The longitudinal fold is substantially parallel to the longitudinal seams. When the expandable slit sheet material is in an unexpanded form, the exterior sheet material extends farther away from the longitudinal seams than the expandable slit sheet material extends from the longitudinal seams. The expandable slit sheet material in each of the bags is expandable from the unexpanded form to an expanded form.

摘要： A web of preformed bags includes a sheet material and a cushioning material. The sheet material includes two sheets that are arranged to form a series of bags. The sheets are connected together to form sides of each of the bags. Each of the bags is bounded by an opening and the sides where sheets are connected together. The cushioning material is coupled to inner surfaces of the sheets in each of the bags. The web further includes a line of weakness in at least one of the sheets between each of the bags. After an object is loaded in one of the bags, the opening of the one of the bags is configured to be sealed closed with the object therein such that the cushioning material in the one of the bags is arranged to cushion the object when the one of the bags is sealed closed.
