the more i mull this over the less likely an issue it appears to be... as long as they contain no actual plastic you should be fine, (esp if it's polyethylene which only starts losing stability at much higher temps than those being touted...)
sure, i wouldn't use any old plastic bag but most of what you'd be able to purchase in a supermarket these days would have been spec'd safe for use in microwave ovens, which would require them to be stable to temperatures far in excess of those required to cook the food...
to be fair, i love a slow-cooked meal, but this just smacks of foody elitist twaddle... until i've tasted the apparent difference... (and i don't get how fillet could taste the same without a little searing :/ ...)
