An inflatable packaging material includes two outer films, a plurality of valve films, and a non-sealable material positioned between the valve films. The films are sealed together by a plurality of seals, including a valve seal extending across the material. The seals define a plurality of air columns and an inflation passage in communication with the columns. The non-sealable material is arranged to form valve portions positioned along the valve seal and spaced passage portions positioned along the inflation passage. The valve portions provide valve passages through the valve seal, to allow airflow into each air column. The passage portions are arranged such that one side seal passes through a space between the passage portions to seal one end of the inflation passage, and the other side seal passes through one of the passage portions to create an open inflation port. The valve films allow air to pass through from the inflation passage to the columns, and prevent reverse flow of air from the columns into the inflation passage.
