When the Hatschek Group sold its shares in 1991, the Wietersdorf found itself faced with a new partner. However, the new partners could not be more different: one of them was a regionally active family enterprise looking back on 100 years of tradition; the other was an internationally ambitious capital company that pursued totally different concepts and objectives (keyword: shareholder value maximisation). Hardly surprising, the partnership merely lasted a couple of years before, in 1997, the Wietersdorf also bought the other 50%-share in Poloplast. Now that the situation had been clarified, nothing stood in the way of a continuous further development and internationalisation.
