The soft drink bottles have multiple layers -- the outer 
layer might not be food grade.

Yes, at the time of manufacture.  ... and after that?

No. -- It is to avoid any transfer of taste/flavor from 
the bottle to the cordial.  The lid/cap offers the same 
risk.  

Case in point proved the one time I used empty Grolsch 
flip top bottles to transport cordials.  Even though the 
bottles had been thoroughly cleaned, the cordials were 
ruined by the yeast taste hiding under the rubber washer 
in the cap.

Yes

You can reuse the bands -- you should use new lids each 
time.  

Next time you have the lid from a jar of spaghetti sauce, 
note how the inside of the lid has changed color from 
white to red -- just try getting it back to white.
