JIS G3303:2008 ISO9001:2015 T1-T5 Electrolytic Tin Plate Coil for
packaging box
Tin-plated coil, commonly known as tinplate (SPTE), is a cold
rolled sheet steel with a thin layer of metal tin plated on the
surface.
There is a certain degree of strength and hardness, good molding
and easy to weld, tin layer is non-toxic and tasteless, and the
surface is bright, tin is mainly to prevent corrosion and rust.
According to the production process is divided into hot tin-plated
steel plate and electroplated tin steel plate. Commonly used
canning jars or beverage cans, etc. is made of tin-plated sheet.
Tin-plated coil (commonly known as tinplate) is a stampable thin
steel plate as a substrate, tin-plated on its surface, with a
multi-layer protective film (layer) of steel products.
It is corrosion-resistant, non-toxic, tasteless, glossy surface,
light weight, high strength (relative to paper, wood, composite
materials), easy to paint prints, easy to weld and process molding,
as well as adaptability to ambient temperature.
Therefore, more than 70% of the total output of tin-plated steel
plate is used for packaging of food and beverage. In addition, it
is also the packaging and raw material shaking of chemical and
pharmaceutical, electromechanical, hardware, telecommunication and
instrumentation industries.
The main feature of tin-plated coil is that the tin-plated layer
has electrochemical cathodic and anodic protection of the dual
performance, that is, in the presence of complex mixtures (or weak
acidic solutes) and a certain degree of vacuum within the walls of
the food cans, the potential is lower than that of the base
material iron, tin for the anode, which is dissolved so that the
protection of iron, in the validity period of the cans of food, the
amount of dissolution of tin is basically harmless to the human
body; and the outer wall of the atmospheric solutes in, the
tin-plated layer and was Cathodic protection state, there is enough
chemical stability, which is incomparable to other can-making
materials.
