non-curling banner material

[petepaz]

have a customer we make banners for approx 48" x 72"
they have from a frame they already have. it's a T frame.
i am printing on a ultra flex 15oz smooth, block out banner material
apparently when it hangs the end curls.
i figured just make a pole pocket and they can put a dowel in to keep it flat but they also want me to see if there is a banner material that will hang flat.
anyone know of such material?

We have used LG Xign with good results. Trim usa has it I believe.

Duratex No curl Poly if they have it available....or Ultraflexx makes a non-curling poly as well. Either of those do not cup on the edges.
