Packaging Materials in Comparison – Focus on Tinplate

In this two-part series, we highlight the characteristic features of both materials and their respective areas of application. In this article, we introduce the key material properties; the next Report will focus on recyclability and the recycling process.

Aluminum – Lightweight and Corrosion-Resistant

Aluminum is known for specific material characteristics. Above all, its low weight—it weighs only about one-third of steel—makes it especially attractive for applications where transport weight plays a major role. Additionally, aluminum exhibits high corrosion resistance due to the formation of a protective oxide layer. These properties make it a suitable solution for certain storage conditions and products requiring strong protection against moisture. Aluminum also provides effective barriers against light and oxygen, along with high thermal conductivity, which is useful in specialized applications.

 

Tinplate – Strength, Protection, and a Closed Material Loop

Tinplate, a fine layer of tin-coated steel, offers an impressive combination of mechanical strength, excellent barrier properties, and industrial versatility. Its high resistance to physical stress—such as impact or pressure—makes it the material of choice for packaging subjected to demanding conditions, such as construction, manufacturing, or harsh environments. Whether during storage, transport, or industrial use: tinplate delivers reliable protection.

Another key advantage lies in its magnetic properties, which not only facilitate automated processing but also ensure efficient reintroduction into the material cycle. Unlike many other packaging materials, tinplate can be sorted and recycled at high speed and with minimal loss. In Europe, the recycling rate for tinplate exceeds 90%—a top value achieved through an established closed-loop recycling system. The recycled material is reused in equivalent applications without any loss of quality—making a significant contribution to the circular economy and resource conservation. In addition to its functionality, tinplate also excels in terms of design: it is highly printable and thus particularly attractive for high-quality product packaging. At the same time, it reliably protects the contents from light, oxygen, and moisture—an essential factor for the durability and effectiveness of sensitive products.

Conclusion – A Future-Oriented Choice of Material

Whether for technical products, decorative packaging, or highly sensitive contents, the choice of packaging material should take both functional and ecological aspects into account. Tinplate combines mechanical strength, excellent product protection, and outstanding recyclability in a single material. In applications where performance, sustainability, and circularity are all critical, tinplate offers a particularly forward-looking solution.

 

In many industries, from the chemical-technical sector to the food and cosmetics industries, choosing the right packaging material is crucial. Products such as paints, varnishes, adhesives, or sensitive ingredients each place very specific demands on protection, handling, and sustainability. Two metals are particularly in focus: aluminum and tinplate. Both materials offer functional benefits, but tinplate stands out for its combination of strength, versatility, and closed-loop recyclability.
