Many people don't know what tinplate is. In fact, tinplate is a metal material. The reason why it is called tinplate is because the outer layer of the iron sheet is plated with a layer of tin, so it is also called tinned iron.

Why are aerosol cans almost all made of tinplate?

The liquid in the aerosol can is formed by pressurizing a certain gas with a gas compressor. The pressure inside the can is much higher than that of the air outside, so the aerosol can sprays a white aerosol, all of which are nano-scale.

If you want to withstand high pressure items, the rigidity of the jar must be very strong, otherwise it is easy to deform or even explode. Therefore, when choosing packaging, metal materials are the most suitable, such as stainless steel or tinplate.

Let's compare stainless steel cans and tinplate cans to see why aerosol cans almost choose tinplate cans. I believe everyone is very familiar with stainless steel, it is not only rigid, but also will not rust! The lifespan is particularly strong, and it is a very good choice in the packaging, but it also has its shortcomings, that is, it is too expensive! And what about tin cans? The same is true for tinplate cans, which are not only rigid, but also won't rust. It has strong extensibility and can be used to make aerosol cans of different shapes through molds, such as round cans, square cans, spherical cans, special-shaped cans, etc. In short, it can meet all your requirements. Another important point is that in the metal packaging industry, the price of tinplate cans is the cheapest. In the market, the price of iron itself is also cheaper than that of aluminum and stainless steel. You can compare the prices of aluminum tea cans, stainless steel tea cans and tinplate tea cans.

In general, the advantages of tinplate cans are: strong rigidity, opaque, good sealing, no rust, green and environmentally friendly, and recyclable.Shandong Shuhao Packaging, the most professional tinplate production and printing manufacturer, can customize on demand. Welcome to consult.
