Hmm ... here's what I'm envisioning; not sure if this matches what Kern has in mind, but I think it is a bit different than what you are showing in your pictures:
Cut two lengths from an 11" roll, each length 22" long. Slit one side of each piece and unfold to make a 22" square. Lay one square on top of the other, making sure that a smooth section is laid on top of a crinkled section, and vice versa. (Otherwise, the vacuum will not be able to draw all the air out of the bag.) Measure in approximately 6" from each corner and mark; cut off the corners. See the picture below -- the dotted lines represent the cuts that are made. Now you have two octagons, one on top of the other; each side of the octagons is approximately 10" in length -- this should fit into the sealer. (If it doesn't, cut the original squares down to, say, 20"). Seal up enough seams to give you a bag; bag the cheese, and seal up the rest.
Disclaimer: I haven't tried this, so I am just theorizing that it will work!!
