If you wanted to use the bag I would cover the pie with parchment paper so the bag doesn't touch the pie - come to think of it - I wonder if doubling up some parchment and making a bag out of it would work. I really don't trust these bags today - God only knows what land fill they came from. Think about it - trees that were in floods, or exposed to harsh chemical fires, etc. Plus what is in them that is making these bags so brittle - not like the good old days!
