I don't know what's going on. I recently got a 50 pack of Graphix shrink film. Not the kind you can put in your printer. This: http://www.amazon.com/Grafix-KSF50-C-2-Inch-11-Inch-50-Pack/dp/B002H9RS66/ref=sr_1_fkmr0_1?ie=UTF8&qid=1337413919&sr=8-1-fkmr0&tag=27411-20
It's not going right at all. The very first thing I tried to make was a ruler. It curled up on it's self and stuck together and there was no uniformity in it's shape at all. This was at 325 for 2 minutes. I put the plastic on a sheet of newspaper with nothing on top.
So then I set the oven to 350 and I put a new copy of a ruler on a sheet of newspaper with more newspaper on top of it so it wouldn't curl up and stick to it's self again. I set it for 3 minutes, but it wasn't enough. So then I set it for 2 more minutes. So finally it shrank but again there were problems. It was skinny at one end and wide at another end, the edges weren't straight and it shrank wayyy more than 50%. I copied a 12" ruler and it shrank down to 4 5/8" long.
What gives? I don't know what I'm doing wrong.
