reflective material for frame/tail bag?

[chrisx]

Some colors reflect light better than others.  Somewhere exist a fabric that could be incorporated into a bike bag.  Everything has a second use.  Why not use your bag as a reflector?  For example, The lower rear section of a tail bag could be made of reflective material.  When rolled closed the reflective material would face the rear no matter the volume in the bag.

Who makes better reflective material?
Better is defined as noticed from a greater distance.
Also, rip proof, light weight, sewing machine friendly, etc.

What about reflective powder coat?
It does exist, but does it work?
