An intelligent oxygen scavenger with oxygen level indication is provided, comprising an oxygen scavenger ( 1 ) and a packing bag ( 2 ). The oxygen scavenger ( 1 ) is contained in the packing bag ( 2 ), wherein the packing bag ( 2 ) is provided with a marker for color changing substance oxygen level indicator and an observation window ( 4 ) is provided in a position corresponding to the oxygen level indicator. The marker for the oxygen level indicator can be an oxygen level indicating layer or an oxygen level indicating line, etc. The packing bag ( 2 ) comprising inner packing film ( 6 ) and outer packing film ( 7 ) on both of which vent pores ( 61, 71 ) arranged in staggered manner are provided. Observation window ( 4 ) is transparent in a shape of continuous lines, dotted lines, round shape or strip like. Inner packing film ( 6 ) and outer packing film ( 7 ) are made of CPP of PE provided with vent pores, complex films of PET/CPP or PET/PE provided with vent pores. The object of the present invention is to provide an oxygen scavenger with oxygen level indication that will make a manufacture or a user to rapidly see the effects of the freshness keeping and oxygen removal of the oxygen scavenger directly. Further, the user is able to rapidly see the oxygen level directly after the oxygen scavenger is used at the same time such intelligent oxygen scavenger with oxygen level indication is easy to produce with low production cost. Further, the intelligent oxygen scavenger with oxygen level indication according to the present invention can prevent the oxygen scavenger from escaping the packing bag with excellent oxygen removal effect and simple manufacturing process.
