Packaging made from graphene, developed by Gerdau and a nanotechnology giant, promises to revolutionize the plastic film industry

The partnership between Gerdau and Packseven could revolutionize the plastic film market with a new technology, since graphene is an extremely versatile material

The partnership between Packseven and Gerdau Graphene resulted in an unprecedented feat in the technology industry: the launch of the world's first Graphene Stretch Film! This collaboration between one of the main Brazilian flexible film companies and the pioneering high performance nanotechnology from Gerdau Graphene promises to transform the packaging market, according to the Plástico Sul website.

Gerdau's new Graphene Stretch Film is a thinner and incredibly resistant version compared to the original Graphene-free material. This technology innovation was developed together with Gerdau with the objective of offering a more robust and resistant film to the market. Kléber Ávila, CEO of Packseven, highlights the advantages of the product: greater resistance to offensive materials, such as points that could pierce it, greater performance, reduced consumption in stretching and, consequently, a significant improvement in cargo safety.

Flavia Zangrandi, Head of Products at Gerdau Graphene, underscores the importance of graphene technology as a highly studied material that is relatively new to the market. Gerdau Graphene is one of the few companies in the world that develop additives and products with nanomaterials and carbon-based technologies, known as graphene, on a commercial scale. Through the partnership with Packseven, Gerdau is delivering to the market a high-performance, low-weight film, expanding the industrial use of graphene.

Graphene: The strongest material on the planet!

Graphene, considered the strongest material on Earth, is composed of densely packed sheets of carbon, one to ten atoms thick. Its extraordinary chemical, physical, electrical, thermal and mechanical properties have captivated the world since it was isolated in 2004, leading its inventors to receive the Nobel Prize in Physics. 

When mixed with plastics, the graphene technology created by Gerdau provides incredible resistance to polymer matrix, making the plastic material combined much stronger. In addition, graphene improves barrier properties against liquids and gases, provides protection against weathering, oxidation and UV light, and increases electrical and thermal conductivity.

In the case of PE-based plastic films, the addition of graphene technology has shown significant gains in material resistance, allowing for a reduction in film thickness. This addition makes it possible to increase the performance of the technology combined with a more sustainable material, reducing the consumption of virgin plastic or increasing the incorporation of recycled plastic in the final product.

The world's first Graphene Stretch Film has already shown impressive results in initial technology tests, withstanding a 120% greater stretch than common film, and it is expected that the final version, scheduled to hit the market in two months, will show even better results.
