I think it's a worthwhile discussion in the context of this thread... not a fight at all...
The melting point quoted above is for raw LDPE. The stuff a factory would use for making plastic parts and shapes via injection molding.
The flimsy bag-quality LDPE has a lower MP, which will depend on the quality of the plastic used by the manufacturer. Same for other types of plastics.

Emphasis mine...
Reality..... We eat plastic all the time.The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F). These temperatures vary strongly with the type of polyethylene.
Do you use plastic bowls/containers to reheat your food in the microwave? I try not to, but I don't get too worried about it.
My lunch curry was boiling around the edges of my ceramic bowl yesterday. Surely hot enough to soften (and thereby allow leaching from) tupperware.
It's not considered toxic, but, I try to avoid it, especially when an easy alternative is available.
