Partnership in business

SENTREX is a family company that owes its development to building stable relationships with customers and its suppliers. From being a small company offering graphic designs for paper bags and then printing services, it has become one of the key producers of paper packaging in Europe. Our development would not be possible without listening to the needs of customers and adapting our offer to the requirements of a rapidly changing world.


Our products are manufactured on the basis of FSC certified papers, only on the basis of water-based paints. We organize our production ensuring the lowest possible level of production waste and energy consumption.

New technology

We constantly modernize our technology and improve our production methods. The introduced and received ISO 9001: 2008, BRC, HACCP and FSC certificates prove that we meet high requirements for quality management and production hygiene.
