Tinplate Steel Coils For Food Cans
Tinplate steel coils are a good choice for food and beverage cans, aerosol bottles, and chemical containers. Its high barrier properties keep the contents protected from corrosion, preserving freshness and flavor. It also resists extreme temperatures.
The tinplate first undergoes side trimming and then electrolytically cleaned and pickled. The clean substrate then goes through temper rolling. This is done either continuously or in batch-type furnaces.
Durability
Tinplate steel is nontoxic and odorless, making it safe for food contact. The tin coating on the metal is durable and has excellent paintability, making it easy to brand with logos or trademarks. The coating is also resistant to scratching.
The tinplate steel coil is made from cold-reduced, low-carbon steel sheet that has been coated on both sides with commercially pure tin. The tin is deposited using an electrolytic process. This process produces a coating that is hard and shiny. It is also corrosion-resistant and rust-proof. It is also ductile and easily drawn to make the can body.
The tin plate coil is used for food cans, container tanks, water pipes, and vehicle panels. Its surface quality is determined by the tin plating and substrate steel properties. The tin plate is available in different grades, including standard grade and second grade. The tinplate is also produced in a bright finish, which is ideal for decorative applications. This type of tinplate is also rust-resistant and can be used for applications that require high corrosion resistance.
Corrosion Resistance
Tinplate steel has a high corrosion resistance, so its use in food containers ensures that the contents stay fresh and safe tinplate steel coils for food cans to consume. It can also resist temperature change, making it ideal for storing food and beverage products. Its insulation properties also make it a good choice for chemical containers.
Tin plate coil is made from a cold-rolled or hot-rolled steel substrate and coated with tin. Its coating is either silk-screened or printed. The tinplate can be sold in a coil or flat sheets. Coils are easier to handle and can be cut or welded easily. However, it’s important to choose the right tinplate for your needs.
You can choose MR type or L type tinplate, which have a low content of residual elements and offer excellent corrosion resistance. It’s also important to know that the level of migrants from metal packaging into food requires strict regulations and screening. Modern and quick methods like FT-IR, gas chromatography and liquid chromatography mass spectrometry help screen for contaminants and measure their levels in foods. This way, you can avoid consuming unhealthy toxins.
High Barrier Properties
Tinplate is used to make food cans, and it has good barrier properties that protect the contents from contaminants. It also prevents water, oxygen, and light from reaching the content. It is light, airtight and strong, which makes it a safe material for shipping and storage. It is a recyclable material and has good corrosion resistance.
During production, tinplate is rolled into a strip and then coated with molten tin. This is done either continuously or batch-wise. The tin is then passivated to prevent it from reacting with foods or drinks. This step is important because it allows for a quick screen of the coating to identify any potential migrants.
The tin plate can be either equally or differentially coated, with the thicker layer being on what will become the outside of the can. The steel is then passed through Annealed Steel Strip a chromate treatment, followed by an oil treatment to help reduce friction during handling. In addition, a variety of quick screening methods can be used to test for the presence of emerging metal migrants and their toxic effects on health.
Rust Resistance
Tinplate is very resistant to rust, which makes it suitable for food storage containers. Unlike traditional metals, tinplate does not react with oxygen to produce oxidation and discoloration of foods inside the container. This feature also helps prevent tin cans from getting too cold or hot, which could spoil the contents.
The steel substrate used for tinplate coils is composed of carbon, manganese, silicon, phosphorus, and sulfur. The steel is rolled to reduce its thickness and improve its mechanical properties. It can also be passivated to enhance its corrosion resistance.
Depending on the end-use, tinplate can be produced in either a bright or dark finish. A bright finish is the most common and preferred for making tin packaging cans and can ends. It is also used to make industrial equipment and vehicle parts. Other uses include borehole pipes, wheel rims, gas cylinders, water tanks, and truck trailers. The material can be decorated with digital printing or silk-screening to add a personalized touch. It is also available in different tin coating thicknesses to suit specific requirements.
Insulation
Tinplate is a combination of steel and tin that is used for food cans. It is a cold-rolled low-carbon steel strip coated with commercial pure tin on both sides. The coating is applied by electrolytic deposition. It has the characteristics of corrosion resistance, solderability, and high strength. It is also non-toxic and odorless, making it suitable for food contact.
Its high resistance to changes in temperature, rust, and corrosion make it an excellent choice for packaging. It is also highly ductile. The tinplate surface can be painted or stamped, which allows manufacturers to add logos and branding for identification and decoration.
ETP is available in either a coil or a sheet form. Coil is easier to handle for shipping and storage. However, if you require a more precise fabrication process or you are dealing with curved surfaces, you might want to consider choosing a sheet. It is a better option for intricate designs or applications that cannot be done with a coil. Sheets can also be embossed and printed. This enhances its aesthetic appeal and makes it more durable.
