tinplate printing ink has properties such as impact resistance, strong adhesion, heat resistance, light resistance, and good drying properties

In addition to the printing ability of normal printing inks, tinplate printing inks also have properties such as impact resistance, strong adhesion, and high temperature resistance

The composition of tinplate printing ink is similar to ordinary ink. It is mainly composed of pigments, binders, fillers and auxiliary agents. However, because the surface of tinplate is smooth and its absorption is poor, it must be different from ordinary offset printing inks. In addition to the printing ability of general offset printing inks, tinplate printing inks also have properties such as impact resistance, strong adhesion, heat resistance, light resistance, and cooking resistance.

Tinplate coil need to be coated with a certain gold lacquer coating on the inner surface, in order to prevent the chemical interaction between the filling in the tank and the tank wall and the contamination of the filler by trace elements, It's time to protect the quality of the filler. The packaged product can be stored, transported and sold for a long time without affecting the use value of the product.

The metal material of the three-piece tin body is tinplate. The metal packaging material for the top and bottom covers can be tinplate, chrome-plated iron, and aluminum. In addition to aluminum, it will not rust. Tinplate and chrome will rust when exposed to wet environments. The use can isolate the contact between metal materials and the outside world, avoid abrasion of the metal substrate, and prevent the corrosion of the substrate by the corrosion factors in the food.

In tinplate printing, in order to improve the adaptability of post-printing and improve the gloss of the appearance and text of tinplate products, the printing ink should be glazed before the printing ink is completely dried to form a uniform and smooth coating film to avoid bleeding. . Coating varnish can not only improve the gloss, but also enhance the flexibility, impact strength, abrasion resistance and adhesion of the surface of the ink layer. In addition, the coating film formed after the varnish is cured at high temperature isolates the ink coating from the outside world and protects tinplate products from physical and chemical substances.

whether the viscosity of the coating is too high or too low will affect the quality of the coating, and the control of the viscosity of the coating is mainly achieved by adding a diluent. At the same time, changes in the ambient temperature will also cause the viscosity of the coating to change, and the viscosity will decrease as the temperature increases.

Coatings are mainly composed of film-forming substances, pigments, driers, auxiliaries, solvents, etc., and can be divided into three types of coatings: inner coating, outer coating and varnish from the coating method and function. It protects the ink layer and increases the brightness of the image to make the product have a good metallic color. At the same time, coatings such as food cans can effectively prevent the contents from being chemically and biologically contaminated, reduce the possibility of leaking the cans, protect the original flavor and color of food, extend the storage time, and make the contents easy to pour out of the containers.

In our lives, we have a lot of gifts, all of which are packaged in tinplate tin boxes. There are many people who don’t know much about it. Why are all these gift boxes used?

Tinplate not only has excellent performance as a packaging material, but also can be made into different shapes, which makes the packaging container more changeable and promotes the growth of product sales. It can be said that tinplate packaging is a creative work product that combines art and technology.
