Single Reduce Electrolytic Tinplate SR-1.5CA ETP 0.17mm Thickness Tin Coated Steel Used For Food And Beverages Cans
Product Introduction:
Tin mill products include electrolytic tinplate,electrolytic chromium coated steel (also referred to as tin free steel or TFS),and black plate,the uncoated steel.
Tinplate is thin steel sheet coated by tin,while TFS is an electrolytic chrome plated steel consisting of a thin layer of chromium and a layer of chromium oxide deposited on the steel base.
Both of them have a beautiful,metallic luster as well as excellent properties in corrosion resistance and paintabillity.

Note: The tin coating weight is determined in accordance with specific end use applications. Tinplate with a heavy coating weight is used for making cans that require a high corrosion resistance or those used bare. Tinplate with a light coating weight is used for making cans that do not require so high a corrosion resistance or those used after painting or printing

Manufacturing Process:
Dingang is the manufacturer of tin mill products in China with advanced technical enquipments,first class inspection devices,skilled operators,excellent sevices and outstanding product development personnel.
It possesses integrated process lines including ironmaking, steelmaking, hot rolling, cold rolling and coating. The product catalogue covers ETP and TFS with an annual output of 100 thousands tons.Our tin mill products are widely sold and used throughout the world in application of packaging of food,beverage and industrial goods an enjoy high reputation in the global market.
Tinplate and TFS products are manufactured under strict quality control all through the manufacturing process to provide the excellent corrosion resistance and uniform material properties required of can-making materials.
Tinplate Products' Features:
| Corrosion Resistance | Selecting a proper coating weight,appropriate corrosion resistance is obtained against container contents |
| Printability | Printing is beautifully finished using various lacquers and inks |
| Weldability | Tinplate is widely used for many types of cans making by soldering |
| Formability & Strength | With a proper temper grade,appropriate formability is obtained for applications as well as the required strength after forming |
| Pretty Appearance | Electrolytic ETP is characterized by its beautiful metallic luster.Kinds of surface roughness are produced by choosing the surface finish of the substrate steel sheet |
TFS Products' Features:
| Paint Adhesion | With excellent paint adhesion properties that far surpass those of ETP,allowing its use for DRD cans and adhesive bonded cans making |
| Heat Resistance | High-temperature baking causes neither discoloration nor deterioration in material properties |
| Resistance To Sulphur Blackening | Metallic chromium has excellent sulphide resistance property when canning protein-rich foodstuff such as fish.TFS compensates for the expensive sulphur resistant lacquer |
| Filiform Rust Resistance | TFS has a great under film corrosion resistance |
| Alkali Resistance | The coating of TFS is not amphoteric.Alkaline products such as detergents and dispersion colours can be packed in TFS with advantage |
Different Features Between TFS & 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 also can be used with 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 produced |
Advantages of Tinplate Cans In Food Packaging:
1)Hygienic: Providing excellent and non-toxic barrier properties to protect food products from impurities,bacteria,moisture,light and odours
2)Safe: Low weight and high strength can make food cans easy to delivery and store
3)Eco-friendly: 100 percentage recyclable that with significant cost benefits compared with aluminium
Applications of Tinplate and TFS:
Consumer Packaging and Industrial Packaging:
| Tinplate | ETP is primarily used for packaging foodstuffs and beverages, but it is also used in containers for oils, grease, paints, polishes, chemicals and many other products. Aerosol containers and caps and closures are also made from ETP |
| TFS | TFS are most frequently used for can tops, screw and lug caps, snap and press-on closures and shallow-drawn food cans |
Other Use Purpose:
1)Electronics: Electrodes, Cable tape, Magnetic screen covers and etc
2)Engineering: Automotive oil filters, Automotive air filters, Gaskets and etc
3)Construction: Gas meter internal components, Heat exchangers, cookware, shelving and so on
