If it's of any help, in my limited experience, when I have small bubbles 
I use a sharp point to poke a *tiny* hole through the cover sheet and 
resist, then run it through the laminator again. Preferably at the 
trailing edge - the last part that will go through the laminator. The 
hole should allow the trapped air to escape, and since the resist is 
gooey when hot it usually clears the bubble and seals up nicely. Not 
always 100% effective, but it works often enough for me to bring up.
