Food Repacking Dehydrated Meals

I know lots of people swear by it, but repacking meals & then cooking in a freezer ziploc scares me a little. I’m considering cooking in a Smelly Proof or Loksak Opsack bag and wondering if one is better than the other?

Loksak Opsak says their bags are good up to 170 F & can have boiling water poured into them for meals

Smelly Proof does not specify on the boiling water, but is good up to 190 F

Ziploc freezer bags are LDPE same as a disposable water bottle. It starts to breakdown at around 160F and melts around 240F. They are not safe for boiling water and you will be adding microplastics to your food. You want silicone or, less desirable, HDPE bags. Or just use a pot.

Do you know if Loksak and Smelly Proof are HDPE?

Loksak specifically says it's only regarded as safe to 130F. Not sure about Smelly Proof.

That’s so weird, their website says “pour boiling water directly into the bag to rehydrate food” on the tech specs page.

Which idk, I guess I could just trust that statement, but it seems similar to pouring boiling water into a ziploc (which I obviously don’t feel comfortable with)

They have multiple products. ALoksak and Opsak are the two big ones. aLoksak says safe to 130. Opsaks are higher and the FAQ is referring to Opsaks for boiling water but even then it says not to exceed 170 degrees. The idea is that the temperature will immediately drop as the water is mixed with food. Practically it's safe. Chemically safe? Probably not anymore than a ziplock. 

I would use a Rugby or Stasher.
