A foldable sandwich bag includes a wall of laminated structure having an inner layer of waterproof, thin, easily tearable material, such as aluminum foil, and an outer wrap securely attached thereto to form a laminate. The outer layer is made of thicker, stronger, tear-resistant material, such as vinyl tape, and is configured in segments that can be torn away along with the attached inner layer to reveal the contents of the bag. The bag can be laminated in a flat configuration and formed into a bag with overlapping vertical seam and having a vertical separation between segments.
