A container having a window for viewing the product contained therein and an associated method of manufacture is provided. The container is constructed of at least one body ply and a liner ply. The body ply defines at least one aperture therethrough such that when the body ply is wrapped into a tubular shape the aperture forms a window through the body ply into the container. The liner ply extends across the aperture in the body ply and has a sufficiently low opacity that allows the product in the container to be viewed through the window. The liner ply provides a moisture and gas barrier inside the container around the product. The container may include a label ply. The label ply defines at least one aperture therethrough. The cuffing of the at least one aperture in the label ply is registered. The body ply defines at least one aperture therethrough corresponding to the at least one aperture in the label ply. The body ply is wrapped around the previously wrapped liner ply on the mandrel and then the label ply is wrapped around the previously wrapped body ply and liner ply so that the apertures in the label ply are aligned with apertures in the body ply to create a tubular shape having a viewing window through both body plies.
