What is the best kind of packaging to help prevent freezer burn, and what is the worst kind? - freezer packaging
Me and my friend did a science project for FFA, and we asked ourselves, what good is the best type of packaging, prevent freezer burn, and what is the worst kind of packaging?

Freezer Packaging What Is The Best Kind Of Packaging To Help Prevent Freezer Burn, And What Is The Worst Kind?

Model best vacuum sealed heavy plastic containers. Even worse is the waxed paper or foil on a roll.
Frostbite includes up to the moisture in the food after they escape frozen by a process of sublimation (direct conversion from solid to gas) to. The closer gas and water vapor permeability of tight package, the better. Worse would be very porous, such as paper towels or brown paper wrapped around the food after it is frozen. Can a reference to wax paper (enough water vapor in the middle, but no seams closed). Next sheet can be completely vapor-proof in the middle, but only a little tighter seams, and only if it actually works on the crimping of closed joints. This could be thinner, the next zip-lock bag with a strong eight each, with excess air sucked in, and better than the volume of air inside. The best is probably vacuum sealed bags (or almost no air trapped inside and seals very well).
But it should really be seen. I suggest you start with the samples that were frozen without packaging (eg, preparing similar pieces of meat in a baking dish quick freezing), which are covered with various materials. Note that forTransport to go to the envelope to the results that can be a rack with a separator for all the samples in air traffic have similar type. After some time of storage, thaw all samples and compare the situations. This comparison is another issue worthy of much thought.
