ABSTRACT:
There is disclosed herein a window-style bag which includes a removable coupon overlying and a transparent window-forming area where the consumer may view the contents of the bag. The coupon section overlies the transparent window-forming film and the bag aperture which forms the window. The coupon is intended for removal, and when so removed, the window viewing area is opened or enlarged, and the bag's structural integrity is substantially unaffected. In practice, the viewing section may be polygonal but is usually rectangular, but the coupon may be secured along two, three or four sides to the bag.
