Why is tinplate bottle caps indispensable?

Tinplate bottle caps are a common type of bottle caps. They are basically used on beer bottles and canned bottles. Bottled Coca-Cola, Sprite and other soda bottle caps are also made of tinplate. Tinplate is an iron sheet with a layer of tin on the surface. It is not easy to rust. It is also called tin-plated iron and is an important metal bottle cap material.

Compared with plastic bottle caps, tinplate bottle caps are more difficult to open, especially for those with less strength. It sometimes takes a lot of effort to open cans and soda bottle caps. The various bottle cap opening skills and assistants on the Internet are a good proof of this. In addition, beer bottle caps need to be opened with the help of an opener. So, why do manufacturers continue to use tinplate bottle caps regardless of consumer experience? Of course, there is a reason.

First, the characteristics of steel: the substrate material of the tinplate bottle cap is cold-rolled thin steel plate or steel strip. Basically, it is actually a steel material. In this case, it must have the high strength and excellent formability of these steel materials, and can easily process various styles of bottle caps, and ensure that the bottle cap has a stable and non-deformable structure when in use, and can be used for a long time while ensuring that the bottle body has a reliable seal.

Second, the characteristics of tin: The reason why the tinplate bottle cap has the characteristics of tin is that the tinplate material used is plated with commercial pure tin on the surface, and it is tin-plated on both sides. In this case, the bottle cap must have a tin appearance, thus presenting a beautiful appearance, and it can also have the solderability and corrosion resistance of tin, and can be sealed by welding, and achieve durable and reliable use.

Advantage 1: Corrosion resistance. Because the tinplate bottle cap is plated with tin on the surface, which can play a good role in preventing corrosion and rust, the bottle cap has very good corrosion resistance and will not easily rust during use.

Advantage 2: Non-toxic. From the perspective of basic materials and raw material costs, the tinplate bottle cap does not contain any substances harmful to human health, so it has non-toxic characteristics and can be used in food packaging.

Advantage 3: Good ductility. Tinplate is a material with good ductility, so it can be easily made into a relatively thin bottle cap with a larger plane area.

Advantage 4: High strength. The tinplate bottle cap has a very high strength and will not easily deform its structure, so it can maintain a stable sealed package during use.

Advantage 5: Provide an effective source of iron. In addition to the above-mentioned aspects, the tinplate bottle cap can also provide an effective source of iron elements during use, that is, it can provide the required trace iron elements, so compared with other ordinary types of bottle caps, it attracts more users.

Finally, in addition to the above-mentioned aspects, tinplate bottle caps also have the advantage of being opaque, which can better guarantee the quality and will not cause quality problems due to exposure to light.

In the actual application process, the tinplate bottle cap has good sealing performance, which can better ensure that the product in the bottle will not have quality problems due to chemical reaction with air. Secondly, the tinplate bottle cap also has the reducing effect of tin during use. It can react with the residual oxygen in the bottle during the application process, which can achieve a better preservation effect.
