You are correct; most everything is permeable to some extent. Permeability is the result of many factors, including lattice structure, dipole interactions, hydrogen bonding, electronegativity, pressure differential, and London forces (I'm sure I forgot something). Polymers vary in permeability depending on their macromolecular arrangements.

Well, polymer chemistry is a field unto itself.

OK, molecular motion stops at 0 Kelvin (-273.15C ). Freezing point of pure water @ atmosphere is 0C, 273K, 32F.

Jesus. Every now and then, I forget what a friggin' brilliant mind you have, Schluss. But it never takes more than one post to remind me. You are one smart dude, buddy. Kudos!

Thanks, amigo. Are you biking in this cold weather or hanging indoors? It's too cold for me and it's only gotten down to below freezing a couple times so far.

The goofy alien is on the "more smileys" page. Wish we had some of these over there at the other place. There's a few I'd like to use for Marky-mark and Gnashie posts.

Ok what ever,

I'm just going by state regs for storing food for public use. If you take a cooking course the first thing you learn is that freezer burn is caused by temp varation not storage container.

I have a deep freeze in my basement, not frost free and I store meats for over a year with no problem of freezer burn. Hell I just took out deer steaks from last season and they look great. No special packaging just plastic bags.

To each his own

I like to point out that doing a bit of research, this is what I found to cause freezer burn to food:

Most likely, your food was not tightly wrapped enabling water molecules to escape and seek a better location.
Also, freezer burn is likely to occur for items stored in the freezer too long. There is a limit to how long items should be stored in the freezer. Sooner or later the water molecules will find their way out of the frozen food to a colder place in your freezer.
The temperature of your freezer may have been above 0 degrees F. Freezer burn will set in from fluctuating temperatures above 0 degrees F.

So I have to say that Lat was correct in her explanation.
