I just got home from a backpacking trip the day before Thanksgiving with a large group. Several people where using the freezerbag cooking method which Ive seen before, apparently it was my friends wife's first time. She is a well paid chem eng so I can only assume that she knows what she is talking about, but when she saw these folks pouring boiling water into freezerbags her jaw dropped. She is a very quiet lady and never gets into other's affairs, so to see her speak up on this matter surprised the group. Im not sure what these FB cookers have been reading but they basically told a chem eng that she was being a "worry wart" (?) and that its perfectly safe.
I just wanted to know if anyone is still using this method?
I did find enough data to keep me from never doing this. Specifically the fact that the softening point of Polyethylene is 157 to 265°F; 262 reaching melt.
Is this something thruhikers would even do?
