A packaging tray to be folded from a blank of paper-like material, comprising end wall panels and side wall panels; the side wall panels are twice as high as the end wall panels so that the side wall panels may be double folded, with the outer side wall panel half laying on the outer side in contact with the exterior surface of the inner side wall panel half. The tray is maintained in shape by an enclosing envelope of transparent film material. Its assembling, filing and wrapping may be executed in one integrated process.
