No. Ziploc® brand Bags are not designed to withstand the extreme heat of boiling.
And to think we used to heat tin cans of beef and beans right in the fire, never knowing that BPA existed.
212ºF is extreme heat?
The manufacturer may not recommend boiling, but it works just fine. It might leach crazy plasticizers into the food, I'm not sure, but the bags hold up well in a pot of boiling water. I've done this several times and have experienced only mild side-effects, including ankle bearding, wandering nipple, and brain tooth.
But in any case, vacuum sealer sounds like a much better idea. I'm sure the sous-vide bags are designed to be used at temperature and not plasticize your food.
