Technical Field
The utility model relates to the technical field of packaging materials, in particular to a packaging film for an oxygen-indicating deoxidizer.
Background
The deoxidizer is also called an oxygen scavenger and an oxygen absorbent, is an additive capable of absorbing oxygen and slowing down the oxidation of food, and is a new product adopted in the food preservation at present. It is a chemical mixture which can easily react with free oxygen or dissolved oxygen, and is placed in a sealed paper bag with a certain air permeability and strength, and is sealed and packaged together with food in the food bag like desiccant bag, so that it can remove the oxygen remained in the air in the food bag, can prevent the food from changing colour, deteriorating quality and rancidity of oil and fat, and also has the action of inhibiting growth of mould, aerobic bacteria and grain pests.
At present, the deoxidizer is not only used for keeping food quality, but also used for preserving and preventing rust of grains, feed, medicines, clothes, fur, precision instruments and other articles.
