When you ask the manufacturers about "cooking" in freezer bags, they assume you mean boiling in a bag or using it in a microwave, which is how most people cook in plastic . Freezer bags certainly were not made for that. We need to specify that we are not cooking but rehydrating dried food by pouring hot (no longer boiling) water into the bag and letting it sit, inside an insulating cozy. This is quite different than boiling or microwaving the freezer bag!


Polyethylene is also the lining of the bags that freeze dried food comes in. The ones that tell you to pour boiling water in them.

Microwaving in any plastic can be a lot of fun particularly if the food has a high fat content. You can get the plastic much hotter than melting temperature. Beef with polypropylene sauce, num-num.

BTW polyvinyl-chloride is a rather nasty plastic and if you're on city water the water in your kitchen sink has probably been running thru miles of it.
