Sealing advantages of tinplate easy open ends
The tinplate easy open lid itself has several difficulties: after the engraving and riveting of the pull ring, it must be easy to open and withstand high-pressure sterilization; the coating film on the inner surface of the tank must be resistant to corrosion by the contents; The engraved line cannot rust after being sterilized by high temperature. So how to solve these difficulties?
tinplate can be divided into primary cold rolling and secondary cold rolling according to the cold rolling production method. Cold-rolled, among which the double cold-reduced (Double cold-reduced, "DR material") product is a second cold-rolled after the first cold-rolled annealing, so compared with the first-time cold-rolled product, it has a thinner thickness , Higher hardness and strength (see
