The utility model discloses a linear oxygen indicator, which comprises packaging film and an oxygen concentration indicative curve provided inside the vertical seal of the packaging film. An oxygen concentration viewing window is provided on the packaging film correspondent to the oxygen concentration indicative curve. The packaging film is also provided with ventilation micropores to ensure every part of the oxygen concentration indicative curve is absolute open for ventilation. In case of any presence of oxygen or the oxygen concentration being lower than 0.1%, the oxygen concentration indicative curve can change colors timely and accurately. The concentration indicative curve can change colors according to the actual effect of deoxidization in the food or product packages, with red for oxygen-free and blue for oxygen-presence, thus effectively overcoming the shortcomings of the current deoxidants of being unable to inspect the effect of deaeration, enabling consumers to learn at first stare the deoxidization and preservation effect of the food. The indicator is simple in process, enabling rapid and mass production on packaging machines, low in cost, the price of the linear oxygen indicator is only one fifth of the price of the current oxygen indicators, which makes the complement use of the oxygen indicator and the deoxidant possible. Moreover, the indicator is convenient for use.
