Silicon, ethylene glycol, graphite, paraffin, etc. can be used. Next, an uncured synthetic resin material is brushed or sprayed onto the surface of the obtained molded body.
Coating is performed by dipping or the like, and then the synthetic resin is cured. In this case, the synthetic resin coating film should not completely cover the entire surface of the oxygen scavenger molded body in a watertight manner. That is, the coating film is at least partially formed with pinholes or thin film portions that allow the oxygen scavenger to diffuse, so that the oxygen scavenger gradually dissolves. For example, by forming a thin coating film with a thickness of about 10 to 2000 μm, vinyl poles are formed in the coating film, thereby allowing sustained release of the oxygen scavenger. Alternatively, a coating film having small pores may be formed by coating with a mask material. Furthermore, water-soluble particles or powder may be mixed with the synthetic resin to be coated. In this way, the oxygen scavenger inside can be eluted through the pores formed when the particles or powder are eluted.
