Are aluminum foil bags prone to oxidation when exposed to air for prolonged periods?

Oxidation of aluminum foil bags will not only reduce their quality, but also generate heat during the oxidation process, spontaneous combustion occurs, and some even exploded.

The chemical oxidation of aluminum foil bags means that aluminum foil bags come in contact with oxygen released by oxygen or other substances in the air, and chemical changes that combine with oxygen occur. The long-term exposure of these products to sunlight can cause discoloration or hardening, which is the result of oxidation of aluminum foil bags. There are many products that are easy to oxidize, such as some chemical raw materials, fiber products, rubber products, oil and fat products, and cotton, linen, silk and other fabrics.

Normally, when exposed to air, fat and oil-based aluminum foil stand up pouch spontaneously oxidize, changing their properties and flavor. This oxidation is generally performed in an auto-oxidative manner, ie in a manner that initiates, propagates, and terminates a three-phase chain reaction. Even the addition of antioxidants does not prevent oxidation, only delaying the induction period and reducing the reaction rate. Or free radicals combine with free radicals to create a chaotic compound. Once the reaction begins.
