The extrusion specialists

The Infinex-Group is the interplay of minds and decades of expertise

Infinex Group

The Infinex Group is made up of companies operating exclusively in the field of plastics processing – from producing semi-finished goods to recycling in the form of granules and compounds that can be put to good use. It operates as an independent group of companies under the direction of its owners, the Hartl family. Haiterbach in the Black Forest is home to this second-generation family of entrepreneurs and has been the headquarters of the Infinex Group’s production and development activities from the outset. Both the group of companies and the regions where the various sites are located have shown themselves to be economically successful and resilient. This is one of the reasons why staff from over 19 different countries choose to stay for so many years. Their expertise, skills and international diversity make them a vital cornerstone of Infinex.

By pooling expertise in plastics technology and plastics recycling from a number of different companies, the group aims to offer even more flexible,
sustainable and customised solutions, so as to meet the growing challenges on national and international markets. An intelligent combination of people and machines optimises workflows and production processes, while also making it possible to act and react faster. Thanks to good instincts, stable continuity and reliable expertise, staff can focus their full attention on what customers need and respond to these requirements.

Infinex Group

As the group of companies grows, production and storage facilities naturally also need to expand. Today we can serve customers the world over – not just from our German facilities located in Haiterbach and Gera, but also from the Czech Republic and North America, thereby ensuring faster and more flexible production and delivery times.

The Brands

Interplast Kunststoffe

The three strong brands of Interplast Kunststoffe GmbH are produced in various countries on two continents using German technology and are sold worldwide. They incorporate ISO-DRAIN dimpled sheets, which have been a tried-and-tested solution in structural engineering, civil engineering and landscaping for decades, as well as TRIPLEX structured-core panels, TRIPLEX pallet enclosures and KIBO twin-wall panels. These panels are used in the packaging industry and in the automotive, events and printing sectors. The three brands have more than just their PP and PE raw mater- ials in common. They also share the same high product quality and benefit from our reliable and courteous service, which customers across the globe appreciate.


Infinex Repoly

Infinex Repoly GmbH is a production and trading company for plastics that became the newest member of the Infinex Group in November 2020. Under the brand name REPOLY, it has already been a successful player on the German and international markets since 2006. Infinex Repoly’s main areas of business include processing, finishing and trading in plastics. It uses not just new materials, but also seconds, surplus production and production waste from the packaging and plastics industry, along with products that have reached the end of their life cycle. These plastics are professional- ly processed and supplied to the market as compounds on a customer- specific basis. To meet the high customer demands, Infinex Repoly works with research and technology partners on an ongoing basis to enhance its products and expand its service portfolio.

ecoline - Recycled materials – sustainable and environmentally friendly
Interplast presents to LogiMAT Fair 2024: ecoline - Recycled materials – sustainable and environmentally friendly!

At a time when the effects of climate change are increasingly making themselves felt and our planet’s resources are becoming ever scarcer, it is more important than ever that we all take responsibility and opt for sustainable measures.

Using recycled polypropylene (recycled PP) offers an effective way of reducing our ecological footprint and making a positive contribution towards protecting the environment. Use of recycled plastic enables us to not only reduce waste and conserve resources, but also cut our CO2 emissions, thus minimising our impact on the environment. By opting for recycled PP, we are demonstrating our commitment to a circular economy and resource-friendly production.

Each and every one of us can play a part in preserving our planet for future generations – so let’s seize the opportunity to use recycled materials and together take advantage of environmentally responsible solutions. It’s time to take action and press ahead with the transformation to a sustainable future.

Together, we can shape the future!
