It did! Heyyyy.... !
Okay, heat transfer is your answer. If the heat is transferred from the bag and absorbed by the water before it can melt the plastic, then the plastic won't melt. Same reason why it takes less time to heat an empty saucepan than it would to heat one full of water.

The heat conducts throug the plastic into the water or think of it as the water cools the bag.

Because the fire is on top of the bag? Okay I'm nitpicking here.
