The inner layer of paper-plastic valve bags typically uses yellow kraft paper, with a plastic film interlayer providing moisture resistance. Additionally, a thin film can be applied to the kraft paper layer, with the film covering the kraft paper, which also serves as a moisture barrier.

The paper-plastic valve bag has two orientations: inward and outward. Generally, outward-facing valves are more common, as they offer better sealing. The printing method for paper-plastic valve bags is primarily offset printing. For simpler design layouts, full-color roll-to-roll embossing printing can be used.
