I number of years ago I was lucky enough to get 30 meters remaining on 
a 440mm width roll. The guy at a place called Printed Electronics in 
Melbourne (I assume your located in Australia) used to run a small PCB 
shop. I asked the owner for some film. He said come back in a week when 
he will changeover the roll in his laminator machine, and leave some on 
the roll. I'm not sure if he is still in business.

Of course , you'll have no problem buying a pair of 500ft length rolls 
for ~AUD$600 IIRC :)

If you can provide the tooling and instructions for applying the film 
then I'm sure there would be a market for it, and you could make small 
profit.

The problem is once its loaded into the laminator machines they can't 
just roll x meters on a plastic tube for you. The protective backing 
film is removed in the machine. You have to ask them to leave a bit 
remaining on the roll.
