Printed Coated Tin Free Steel TFS Tinplate Sheet For Chemical Can
Packaging ETP TFS
ETP TFS is a tin-free steel coil used for chemical tank packaging.
Its full name is Electrolytic Tin Free Steel. It is based on
cold-rolled low-carbon steel plate. Through the electrolytic
process, a very thin layer of chromium or chromium oxide coating is
formed on the surface, replacing the traditional tin plating layer.
It is often used in the field of chemical tank packaging that has
certain requirements for corrosion resistance and printability.
Features
1. Good corrosion resistance: The chromium or chromium oxide
coating on the surface can effectively block the contact between
chemical substances and the steel substrate, resist the erosion of
various chemical substances, and ensure that chemical tanks will
not be damaged or leaked due to corrosion during storage and
transportation.
2. Excellent printability: The coating surface is flat and smooth,
which can provide a good foundation for printing. The ink has
strong adhesion on its surface, and the printed pattern is clear,
firm, and colorful, which can meet the needs of chemical product
packaging in appearance design and identification.
3. High strength and toughness: With low-carbon steel as the
substrate, it inherits the high strength and good toughness of
steel, can withstand a certain degree of collision, extrusion and
other external forces, is not easy to deform or break, and ensures
the stability of chemical tanks in various environments.
4. Environmental protection: Compared with tin-plated steel sheets,
Wuxi steel coils do not require the use of tin resources during
production, reducing dependence on limited metal resources. The
chromium coating is more in line with environmental protection
requirements to a certain extent, reducing potential harm to the
environment.
5. Cost advantage: Since relatively expensive tin is not used,
production costs are reduced. While ensuring packaging performance,
it can save packaging costs for chemical product manufacturers and
improve the market competitiveness of products.
Different Features between TFS and ETP
Appearance
Even when the same surface finish as ETP is applied to the
substrate steel sheet, it provides the unique surface
luster characteristic of metallic chromium.
Corrosion resistance
As it has excellent corrosion resistance after painting, it is
generally used with both surfaces painted. It can also be
used with the internal surface unpainted, depending on the
contents.
Solderability
TFS is not compatible with soldering.
Weldability
Although TFS can be welded when the metallic coating layers are
removed, its weldability is inferior to ETP.
Coating weights
Unlike the multiplicity of coating weights with tin, only one
standardized chromium-coated product is manufactured.
