In addition to tin plating, tinplate sheet manufacturers can also use other surface treatment methods to enhance the durability of the product. For example, some tinplate sheet manufacturers use anti-corrosion coatings (such as epoxy resin coatings, polyester coatings, etc.) to provide additional protection for tinplate sheet.

1. Why is the top of tin plate cans called "can lid"? The top of tin plate cans is usually called "can lid" or "lid", which is used to close the can body and isolate the internal contents from the outside world. Depending on the purpose, the tin plate cans lid will adopt different designs.

Tinplate containers and plastic containers have their own advantages and disadvantages and are suitable for different packaging needs. Tinplate containers are suitable for food or daily necessities that require long-term storage and high corrosion resistance, while plastic containers are suitable for the packaging needs of daily consumer goods with their lightness and economy.

The anti-corrosion performance of electrolytic tinplate mainly comes from the tin layer. Tin is a metal that has strong antioxidant properties and is not easy to react with oxygen in the air, so it can effectively prevent the oxidation process on the iron surface.

Due to the moisture-proof, light-proof and anti-oxidation properties of tinplate food packaging cans, it can provide a relatively stable and closed environment for tea, thereby delaying the loss of tea flavor. Therefore, the use of tinplate food packaging cans can significantly extend the shelf life of tea.

Common printing processes for metal packaging tins are: 1. Flexographic printing: suitable for mass production 2. Letterpress printing: suitable for large-area design 3. Offset printing: suitable for high-quality images 4. Screen printing: suitable for special effects and small-volume customization

Aerosol cans are a closed metal can that uses internal gas pressure to spray liquid or semi-solid substances in the form of mist. Its basic working principle is to quickly atomize the liquid through internal pressure, produce fine particles during the spraying process, and thus achieve a uniform dispersion effect.

Generally speaking, tinplate cans have a long shelf life, usually more than two years or even longer, but the specific period still depends on the use environment of the can. If tin plate cans are placed in a humid, highly acidic or alkaline environment, the tin coating may be affected, thus shortening the overall shelf life of the can.

The advantages of offset printing are reflected in the following aspects: 1. High-quality printing effect 2. Suitable for large-scale printing 3. High color reproduction 4. Strong ink adhesion 5. Support for a variety of special effects 6. Environmental protection and safety

As the main material of tinplate plate, low carbon steel itself has the natural color of metal, usually showing a silver-gray or iron-gray metallic luster. This color of the steel surface comes from the essential properties of its iron element, and usually has a strong reflective effect.
