ABSTRACT:
There is disclosed herein a method for manufacturing a bag-in-a-bag system wherein there is provided a content-carrying sealed and opaque inner bag and a windowed outer bag having a layer in the window-forming graphic content replicating indicia. The graphic layer indicia is of a high quality and is prepared by a high resolution printing technique where the minimum resolution is defined as 160-200 line screen. This type of resolution can be achieved using a rotogravure process. For ease in manufacturing, several indicia are printed on a web, which is then longitudinally slit to separate the indicia and then cut transversely into patches for application to the bag. The bag itself may be printed using a lower resolution technique such as rubber plate printing.
