Abstract

The invention provides an oxygen indication type deoxidizer and a manufacturing method thereof. The oxygen indication type deoxidizer comprises a breathable inner film containing a deoxidizer piece and a punching outer film which is provided with an oxygen indication piece, the punching outer film comprises a body part wrapping the breathable inner film and an indication piece leading-in part which is formed in a mode of extending outwards from the body part and contains the oxygen indication piece; the indication piece leading-in portion includes a longitudinal edge sealing region and a transparent region which is arranged between the longitudinal edge sealing area and the body part and covers the oxygen indication piece. The deoxidizing agent piece and the oxygen indication piece are separately arranged, due to the fact that the outer film is punched, the oxygen indication piece arranged in the indication piece leading-in part is large in air permeability and stable in air permeability, the oxygen indication piece is quick in color change and can accurately and directly react to the deoxidizing condition of the deoxidizing agent, the deoxidizing agent piece is wrapped by the breathable inner film, the hole diameter of the the deoxidizing agent piece is small, and the powder leakage phenomenon is avoided; and meanwhile, the area, covering the oxygen indication piece, of the indication piece leading-in part is a transparent area, and therefore the color changing condition of the oxygen indication piece can be observed from the two faces through the transparent areas on the two sides of the oxygen indication type deoxidizing agent.

Description

technical field [0001] The invention relates to the technical field of deoxidizers, in particular to an oxygen-indicating deoxidizer and a manufacturing method thereof. Background technique [0002] Oxygen-indicating deoxidizers generally include deoxidizers and oxygen indicators. Deoxidizers are placed in food packaging bags, which can effectively inhibit the growth of mold and aerobic bacteria, prolong the shelf life of food, and prevent oil from rancidity and meat. It can also play a very good role in preventing oxidative browning and preventing the loss of vitamins in food. In order to know whether the deoxidizer is effective, many deoxidizer products will add oxygen indicator to judge its usability. [0003] Now there are two ways to set the oxygen indicator, one is to fix the oxygen indicator on the deoxidizer bag, but this method can only observe the color change of the oxygen indicator through one side of the deoxidizer bag, which is not conducive to daily use .
