Tinplate, also known as tinplate, is a common name for electroplated tin steel sheets. The English abbreviation is SPTE, which refers to cold-rolled low-carbon steel sheets or strips coated with commercial pure tin on both sides printed tinplate. Tin mainly acts to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of tin in a material with corrosion resistance, non-toxicity, high strength and good ductility.
Tinplate is a tin plate coated with tin on the surface. It is not easy to rust, also called tinplate. This kind of coated steel plate has been called “tinplate” for a long time in China. Some people think that because the tin-plated sheet for canning at that time was imported from Macao (English name Macao can be read as Makou), it is called “tinplate”. There are also other claims. For example, in the past, China used this tin-plated sheet to make the head of a kerosene lamp, which is called a horse mouth, so it is called “tinplate.” The name “Tandil” is not exact. Therefore, in 1973, the Chinese tinplate was called the tinplate, and the official name no longer uses the name “tinplate”.
Due to its good sealing, preservation, light-shielding, sturdiness and unique metal decoration charm, tinplate packaging has a wide range of coverage in the packaging container industry and is a universal packaging variety. With the continuous enrichment of various CC materials, DR materials and chrome-plated iron of tinplate, the development of packaging products and technology has been promoted. The tinplate packaging is full of innovation everywhere.
Because of its strong oxidation resistance, diverse styles and exquisite printing, tinplate packaging containers are well received by customers and are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, and industrial packaging.
The tinplate packaging container has many advantages such as high strength, good formability and strong compatibility with products, which has established a good reputation in the international market. Therefore, all countries generally attach importance to this kind of packaging container, which is the most used metal packaging sheet in the world.
According to the different requirements of the packaging industry, the thickness, tin plating and mechanical properties of tinplate materials have different needs. Since its inception, tinplate has been developing in the direction of thinning. One is to use less tin, not even tin, and the other is to reduce the thickness of the tinplate. The purpose is to adapt to changes in can products and to reduce the cost of can making.
With the continuous improvement and improvement of tinplate printing technology and processing technology, tinplate packaging is becoming more and more widely used.
