The present invention relates to bottle cap technical fields, and in particular to the method for a kind of optical-fiber laser mark bottle cap and using bottle cap made of this method.A kind of method of optical-fiber laser mark bottle cap of the invention, is identified bottle cap using infrared optical fiber laser.Bottle cap is identified using ultraviolet laser in compared with the existing technology and is compared, the output wavelength for the infrared optical fiber laser that the present invention uses is located at infrared band, avoids existing bottle cap material and is easy to absorb the ultraviolet band light of ultraviolet laser sending and lead to the problem of because absorbing ultraviolet band light with penetrating odor.The present invention is using bottle cap made of this method, the content significant decrease of the normal octane, positive flow silane, n-dodecane, n-tetradecane and aldehyde substance of release, to significantly reduce penetrating odor. |
