I had the same problem with my parents. Even 40 yrs later the public has been warned and shown the hazards of smoking around kids, elderly, or others with health issues, but people still do it. Anyways thats a different subject. I am a non-smoker of everything cept foods.
I was thinking the 170 mark you talked about had to do with seal failure. I almost mentioned it last night. The bag itself won't melt at 170 or even 200-212. Even sandwich bags will stay in tact in boiling water. We make omlets in them all the time!
carefull shoveling snow Steve. We got an inch last night, but the bright sun has already done away with it today, just a few piles left around here, and the 45 degrees and sun on tomorrow will take care of them.
Gotta go rub up a couple briskees and a few butts for tomorrows smoke.
GO WINGS!
