TITAN produces PET straps and a big part of their special-purpose machines programme at their site in Goch

The slider of the silo opens up and releases millions of green particles. These so called flakes are actually shredded PET bottles. The material is turned into something else at the TITAN plant in Goch. Here the PET bottles are converted step by step into extremely resilient PET straps. Those green straps make sure that worldwide transportation of building material, wood products, corrugated cardboard, stack of sheets and a lot more is safe. Before processing can begin however, the flakes need to dry.

When the raw material is being funnelled in the extruder, it has covered a distance of 60 metres through the production hall. At first the extruder grinds the flakes. Then they are heated up to 240 degrees Celsius. Now the material has a honey-like texture and moves through several different extruder heads. The end results are strap blanks that are still thicker and wider than the final product.

“Then we quench the blanks in a water bath”, explains Harald Pollehn, TITAN’s General Sales Manager. Now it’s time to bring the PET molecules into the right shape – this means providing the material with more resistance and stability. In order to get there the straps are drawn across several pairs of coils at different paces.

 

The finished strap is between 9 and 32 millimetres wide and between 0.6 und 1.65 millimetres thick. TITAN delivers its PET straps around the world rolled up on standard or up to mega-jumbo coils. “Our biggest coils carry almost 30,000 metres of PET strap. Very few of our competitors can provide that”, explains Harald Pollehn. That is why these straps are very much in demand in Australia as well. Because in contrast to a lot shorter run lengths, these mega coils only need to be changed every eight hours.

In building the site in Goch, TITAN has created yet another solid mainstay to its steel strappings and technologies. Being a systems manufacturer of strapping technology and straps, TITAN convinces with its balanced complete packages for every type of strapping.

Talking about PET straps

Harald Pollehn, Gesamt-Vertriebsleiter TITAN

Mr. Pollehn, at the TITAN factory in Goch you produce PET straps. What would you say are the advantages of this material? PET strap is a material that is 100 percent recyclable. We receive the raw material from different recycling companies, to which we keep a close contact and in whose quality we trust. The high quality of the material assures that the remains from processing flow back into the manufacturing process. Whatever PET material enters the hall will leave on a coil

Will PET strap replace steel strap in the near future?
We’re still expecting growth in the PET sector. Due to its high cohesion PET straps are also very well suited for the strapping of building material, wood and within the metal industry. This means that even when the package shrinks due to stacking, it still holds enough strapping tension. Furthermore PET causes hardly any damage to the edges. Hot steal coils on the other hand have to be strapped by steel straps. So there will certainly be a future for both products.

What happens to the used straps?
We’re members of the German plastic strap utilisation society “Kunststoffbandverwertungsgesellschaft (KBV)”. This is an association established by strap manufacturers. The KBV makes sure, that the used strap is being collected and recycled.
