The principle of the oxygen absorption gasket is that redox substances, namely oxygen absorbers, are added in the gasket material and can react with oxygen in bottleneck, but the introduction of the oxygen absorbers inevitably causes the change of the crystallinity of high polymers, so that the oxygen absorbers are whitened after oxygen absorption, and in order to prevent whitening after placing the oxygen absorption, the oxygen absorbers need to be pretreated, so that the phenomenon of recrystallization of the oxygen absorbers induced in high-temperature water environment (such as the condition of pasteurization method, about 68 ℃) is inhibited, and the dispersion degree of the oxygen absorbers in high polymers is improved, so that the texture of precipitated particles is reduced. In conclusion, the gasket with the formula provided by the invention has the advantages that the gasket has oxygen absorption activity, does not turn white, has few particles, and can clean the two-dimensional code.
