Product Description
According to the difference of the tin plating thickness on the front and back of the thin steel plate, tinplate can be divided into two types: equal thickness tinplate and differential thickness tinplate. Among them, equal thickness tinplate refers to the same tin plating on the front and back of tinplate. Tinplate, also known as tin-plated steel, is a thin steel plate plated with a layer of tin on both sides. The purpose of this coating is to provide corrosion protection and enhance the appearance of the steel. Equal-tinned tinplate refers to the same tin plating on the front and back of tinplate. Equal thickness tinplate acts as a reliable barrier against moisture and oxygen, making it ideal for packaging perishable goods such as canned goods or aerosol containers. Besides, it has excellent printability, allowing companies to create eye-catching designs for their product packaging.
