Will Aluminum Foil Pouches Be Oxidized When Used?

Chemical oxidation of aluminum foil bags refers to the chemical changes that combine with oxygen after the bag is in contact with oxygen or other substances in the air, and these products will change color or harden after long-term contact with sunlight, which is the result of being oxidized. The oxidation of aluminum foil packaging bags will not only reduce its quality, but sometimes generate heat and spontaneous combustion in the oxidation process, so the product must pay attention to the shelf life when using.

Mask packaging: When the product is used to package the mask, the fatty acids in the mask can form hydroperoxides during automatic oxidation, so you must pay attention to protect from light during storage.

Grease-based packaging: When the product is exposed to air, the oil-based aluminum foil bag will spontaneously oxidize, changing its properties and odor. This oxidation usually takes place in the form of automatic oxidation, i.e. initiation, communication and termination of the tertiary chain reaction. Once the reaction begins, it is always depleted by oxygen or free radicals that bind to free radicals. To alleviate oxidation, antioxidants can be added, although oxidation cannot be avoided, but can delay the induction period of the reaction and reduce the rate of oxidation reaction.

Food packaging: food contains a large amount of unsaturated fatty acids, which will make the food taste and deteriorate after oxidation. In addition, oxidation also depletes vitamin A and vitamin C, and the unstable substances in food colors are affected by the action of oxygen, and the color is darkened.
