The invention discloses a roll applied to a zip-top can and a production process of the roll, and relates to the technical field of zip-top can processing. Diamond-like carbon is sprayed on the surface of the roll, a thickness of the diamond-like carbon is 2 micrometers to 3 micrometers, and the production process of the roll comprises the steps of heat treatment and spraying, wherein spraying time in the spraying process is not shorter than 6 h, and a surface hardness after spraying is not lower than HRC90. According to the roll, the diamond-like carbon is sprayed, so that the roll has high hardness and corrosion resistance, the price of the roll is reduced by 15% on the basis of the price of domestic rolls, the service life of the roll reaches 100 million times, the roll is superior to domestic and overseas rolls in price and service life, the low cost, the long service life and the easiness in quality control are realized, and materials and processing equipment are completely domestic. 本发明公开了一种应用于易拉罐的卷封轮及其
