An ovenable bag for packaging heated, greasy food items for display is formed of a laminate having a thin, transparent, polyester inner layer and a relatively thicker and stiffer opaque outer layer formed of a foldable and printable material. The wall structure is generally tubular and is folded to define front and rear panels and gusseted side panels, one end of the structure being folded, heat sealed and then folded again and adhesively secured. The window portion extends the length of the front panel of the bag centrally thereof. The outer layer is bonded to the inner layer along the entire area of the outer layer except for an optional tear strip which may be disposed along one edge of the window. The bag may also be heat sealed along the fold lines joining the side panels to the front and rear panels for added stiffness.

[ We claim:] [1.] An ovenable bag for packaging heated, moist food items for display, said bag comprising:a laminate defining a elongated, generally tubular wall structure having opposed ends,said laminate including a thin transparent inner layer formed of a heat-sealable, moisture-proof and anti-fogging material, anda relatively thicker and stiffer opaque outer layer formed of a foldable and printable material fixedly secured to said inner layer and covering said inner layer except along a window portion of said inner layer extending end-to-end of said wall structure, said window portion having uncovered and breathable surfaces sized to permit the migration of heated moisture from the interior of bag to the exterior of the bag in amounts which prevent substantial fogging of the window portion,said wall structure being flattened, folded and heat-sealed at one end thereof for closing said one end.
