David, I agree with others who have concerns about the folded-over seam you plan to use. All adhesives are stronger in shear (given a reasonable surface area) than in peel. The seam you propose, which is in peel, may be strong enough for your application, but why choose it over seams that are stronger, simpler, and lighter?
In the crude MS Paint image below, seam D is the strongest. Two linear inches of glued seam must be pulled apart to break it. But it's unnecessary because the simpler seam B is probably stronger than the fabric. Seam C, suggested by Jim, is no stronger than seam B. They both can be broken by pulling apart only one linear inch of bonded fabric. And again, seam B is simpler. Seam A (the folded-over seam) will probably pop open to become seam B at tensile forces below the breaking strength of the fabric.
Seam D uses 2/3 the glue of your seam (A), seam C uses half, and seam B uses 1/3 of the glue that the folded over seam (A) requires. Seam A has hidden edges (before it pops open), but the edges on the others won't fray or unravel. They're bonded down.
I apologize for the long, opinionated post. Just still curious about your rationale for using the folded-over design.
