wherein the perimeter seal has a first end, a second end opposite the first end, a first side that extends between the first end and the second end, and a second side opposite the first side that extends between the first end and the second end;

wherein the first sealing station forms the first end, a first portion of the first side, and a first portion of the second side of the perimeter seal to thereby partially enclose the food product in the food product package; and

wherein the second sealing station forms the second end, a second portion of the first side that abuts the first portion of the first side, and a second portion of the second side that abuts the first portion of the second side of the perimeter seal to thereby fully enclose the food product in the food product package.

2. The web packaging machine according to claim 1 , wherein the first sealing station and the second sealing station are spaced apart from each other along the lower web transport conveyor.

3. The web packaging machine according to claim 1 , wherein the first end of the perimeter seal extends parallel to the second end of the perimeter seal.

4. The web packaging machine according to claim 1 , wherein the first portion of the first side and the first portion of the second side of the perimeter seal extend parallel to each other and transverse from the first end of the perimeter seal; and wherein the second portion of the first side and the second portion of the second side of the perimeter seal extend parallel to each other and transverse to the second end of the perimeter seal.

5. The web packaging machine according to claim 1 , wherein the first sealing station has a first seal surface configured to seal the upper web of packaging material to the lower web of packaging material, wherein the first seal surface corresponds to the first section; and

wherein the second sealing station comprises a different, second seal surface configured to seal the upper web of packaging material to the lower web of packaging material, wherein the second seal surface corresponds to the second resection.

6. The web packaging machine according to claim 1 , wherein an area of the first section sealed by the first sealing station is also sealed by the second sealing station.

7. The web packaging machine according to claim 6 , wherein the second seal surface is larger than the first seal surface.

8. The web packaging machine according to claim 6 , wherein the area is a permanent seal that prevents the upper web of packaging material from separating from the lower web of packaging material.

9. The web packaging machine according to claim 1 , wherein the first end, the first portion of the first side, and the first portion of the second side of the perimeter seal mirror the second end, the second portion of the first side, and the second portion of the second side of the perimeter seal.

10. A web packaging machine that encloses a food product within a food product package formed by a lower web of packaging material and an upper web of packaging material, the web packaging machine comprising:

a first sealing station configured to seal the lower web of packaging material to the upper web of packaging material and a second sealing station configured to seal the lower web of packaging material to the upper web of packaging material to thereby fully enclose the food product in the food product package and form a perimeter seal that encircles the food product;

wherein the perimeter seal has a first end, a second end opposite the first end, a first side that extends between the first end and the second end, and a second side opposite the first side that extends between the first end and the second end;

wherein the first sealing station forms the first end and the second end to thereby partially enclose the food product in the food product package, wherein the first end is spaced apart and disconnected from the second end and a space is defined between the first end and the second end; and

wherein the second sealing station forms the first side and the second side in the space between the first end and the second end to thereby fully enclose the food product in the food product package, wherein the first side and the second side each abut the first end and the second end; and

a lower web transport conveyor configured to convey the lower web of packaging material from upstream to downstream first through the first sealing station and then through the second sealing station.

11. A web packaging machine that encloses a plurality of food products within a plurality of food product packages formed by a lower web of packaging material and an upper web of packaging material, the web packaging machine comprising:

a first sealing station configured to seal the lower web of packaging material to the upper web of packaging material to form a first section of each food product package of the plurality of food product packages such that each food product of the plurality of food products is partially enclosed in one of the food product packages of the plurality of food product packages, wherein the first sections abut each other and collectively encircle the plurality of food products;

a second sealing station configured to seal the lower web of packaging material to the upper web of packaging material to form second sections of each food product package of the plurality of food product packages such that each food product in the plurality of food products is individually fully enclosed in one of the food product packages of the plurality food product packages, wherein each food product package is formed by at least one of the first sections and at least one of the second sections; and

a lower web transport conveyor configured to convey the lower web of packaging material from upstream to downstream first through the first sealing station and then through the second sealing station.

12. The web packaging machine according to claim 11 , wherein the first sections define an exterior seal that encircles the plurality of food products, and wherein the second sections define a plurality of interior seals that separate the food products from each other.

13. The web packaging machine according to claim 12 , wherein the exterior seal is rectangularly shaped and wherein each food product package is rectangularly shaped.

14. The web packaging machine according to claim 12 , wherein the food product packages of the plurality of food product packages are separated from each other downstream from the first sealing station and the second sealing station.
