Hydrogen Peroxide comes in many concentrations. At 90% it will decompose rapidly on contact with lots of things ( boom,bang). At 32% it will decompose a little more slowly, not explosively but still very vigorous. Aluminum and plastics are known to have oily surfaces and require cleaning. Oil is organic and the H2O2 will clean the surface,decomposing as it does into water and oxygen. The oxygen vaporizes away and the water is dried off leaveing a clean surface for placing the plastic layer on the aluminum. They would clean the plastic surface the same way before folding it into a box for filling. This is industrial strength and must be handled carefully, it will quickly eat the skin off of you or eat any organic thing it can. At 3% its very safe ,mild, and non-toxic. Its so mild you can buy it in any store for 38 cents a bottle.When they say its a mild anti-septic, thats exactly right, won`t hardly hurt a flea. The 3% concentration will decompose in a few seconds on contact will organic materials as a foaming bubbly cleanser. Most people use it to bleach hair because it is so mild. It is used to loosen dried stuck bandages from wounds because it is so mild and will not harm the tissue. Because of this usage people thought it was being used to disinfect the wound,while in reality it was just to get the dried bandage off. Hydrogen Peroxide is thermally unstable because its formation is a highly endo-thermic process. In order to store it ,it must be stabilized with small amounts of a negative catalyst (stabilizer)such as acetanilide. Heavy metals (copper, silver) will hasten the decomposition into water and oxygen. Storage is in special bottles called *barrier* bottles. Go get your Hydrogen Peroxide from your bathroom and look at the bottle. Its a very dark brown strange feeling plastic bottle. In this bottle it will keep about two years (they have dates on them, usually on the cap). It will self decompose by itself anyway over a few years however hard we want it not to. By the way ,if you have an empty barrier bottle its a great way to store your CS. Barrier bottles are not permeable like regular plastic bottles. They aren`t good from a marketing stand point because they are so ugly (the bottles that is). I`m glad a lot of people are looking into uses for this very useful compound.:-) The government says its ok because its so safe,its so mild,even the kids can play with it (at 3%).
