FAQ

Tinplate is often preferred over glass for packaging applications due to its durability, lightweight nature, and cost-effectiveness. Unlike glass, tinplate is not prone to breakage, making it safer for shipping and handling. It also offers excellent barrier properties, protecting the contents from air, moisture, and light. Additionally, tinplate is recyclable and has a lower carbon footprint compared to glass, making it a more sustainable choice for packaging.
Some of the different coating options for tinplate include electrolytic tin coating, chrome oxide coating, lacquer coating, and organic coatings such as epoxy or polyester.
Tinplate is typically coated with organic materials through a process called lacquering or varnishing. The organic coating, usually a resin-based material, is applied to the tinplate surface in a controlled manner, forming a protective layer that prevents corrosion, enhances durability, and provides a decorative finish.
The typical transportation requirements for tinplate include ensuring proper packaging and protection to prevent damage during handling and shipment. Tinplate is commonly transported in rolled or flat sheets, coils, or fabricated containers, depending on the specific product and its intended use. It is crucial to handle tinplate with care to avoid scratches, dents, or corrosion that could impact its quality. Additionally, proper labeling and documentation are necessary to comply with regulatory and customs requirements during transportation.
The different thickness options for tinplate typically range from 0.13mm to 0.49mm, with various options in between.
Tinplate is not significantly affected by exposure to light, as it is a durable material that does not undergo any noticeable changes or degradation when exposed to light.
There are primarily three types of tin coatings used on tinplate: electrolytic tinplate (ETP), black plate, and tin-free steel (TFS). ETP is the most common type and provides excellent corrosion resistance and solderability. Black plate is uncoated tinplate, often used for industrial applications or as a base for other coatings. TFS, on the other hand, replaces the tin coating with a thin layer of chromium or chromium oxide, offering similar corrosion resistance but without the use of tin.
Tinplate is coated on both sides by immersing the steel sheet in a bath of molten tin. This process, known as hot-dipping, ensures that both sides of the steel sheet are evenly coated with a layer of tin, providing protection against corrosion and enhancing its appearance.
