Corrosion Resistant TFS / Tinplate Coil for Durable and Long-Lasting Packaging Solutions
Definition and composition:
TFS: Tin-free steel sheet, is a thin layer of chromium or chromium oxide film formed on the surface of cold-rolled thin steel sheet through electroplating or chemical conversion to provide corrosion resistance.
Tinplate: Also known as tinplate, it is a sheet with a thin layer of metal tin on both sides of cold-rolled thin steel sheet.
Performance characteristics
1. Excellent corrosion resistance:
TFS: Chromium and chromium oxide do not react with sulfur and alkali, so they have good resistance to sulfur and alkali, and also have good corrosion resistance to the atmosphere, organic solvents, oils, etc.
Tinplate: The tin layer can effectively isolate the contact between air and moisture and the steel substrate to prevent rust.
2. Paintability and printability:
TFS has strong adsorption and wettability to paint, which is more than 2-5 times the adhesion of the same paint on tinplate, which is conducive to surface treatment such as painting and printing, and can achieve exquisite packaging design and enhance the appearance of the product.
3. Hygiene and safety:
Non-toxic: TFS and tinplate are non-toxic in themselves and meet food hygiene standards. They can be directly used for packaging of food, medicine, etc., without causing harm to human health, and can ensure the hygiene and safety of the contents.
Application areas
1. Food packaging: widely used in making various canned foods, such as canned fruits, canned vegetables, canned meat, canned fish, etc., which can effectively maintain the flavor and nutrients of food and extend the shelf life of food.
2. Beverage packaging: It is a common material for beverage cans, such as carbonated beverage cans, beer cans, juice cans, etc. Its good corrosion resistance and pressure resistance can withstand the pressure of beverages and the erosion of acidic substances.
3. Chemical product packaging: It can be used to package chemical products such as paints, coatings, inks, glues, detergents, pesticides, etc., to protect chemical products from the influence of the external environment, and prevent leakage and deterioration.
4. Pharmaceutical packaging: used for the packaging of medicines, such as packaging containers for tablets, capsules, injections, etc., which can provide good sealing and stability to ensure the quality and safety of medicines.
5. Other fields: It can also be used for the packaging of electronic products, daily necessities, toys, stationery, etc., such as electronic product shells, battery boxes, cosmetic boxes, toothpaste tubes, toy packaging boxes, etc.
Market prospects:
As people's performance requirements for packaging materials continue to increase, corrosion-resistant TFS/tinplate coils occupy an important position in the packaging market with their excellent performance and wide application fields. In the future, with the enhancement of environmental awareness and the requirements of sustainable development, TFS/tinplate coils will continue to develop in the direction of green, environmental protection, and high performance, such as developing thinner coatings, more environmentally friendly surface treatment processes, and recyclable composite materials to meet the needs of different industries while reducing the impact on the environment.
| Applications of Tinplate and TFS |
| 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 are most frequently used for can tops, screw and lug caps, snap and press-on closures and shallow-drawn food cans. |
