About us

Sitras has been supplying companies in the plastics industry with plastic granules, colorants and additives since 1990. Our many years of experience and flexible approach enable solutions tailored to the needs of each individual customer. We started as a small company with a big vision – to offer quality materials and reliable support to help companies with their daily challenges.

Our customers often emphasize that they appreciate our speed and reliability in supplying materials that are crucial for the smooth running of their production. They also praise our professionalism and willingness to advise them on choosing the right materials. Many customers started working with us because of our flexibility in orders and transparency in prices, which is why we remain their long-term partner.

At Sitras, we believe that the key to success is building trust and a partnership – and this is exactly what our customers often tell us. Today, after more than three decades of operation, we still strive for the same goal: to be a reliable partner that our customers can always count on.
