The company PROEKO PLASTIKA d.o.o. is 100% private own company. It was founded in the year 2008 and originates from the former company PROEKO Jože Ceglar s.p., which was engaged in the production of gaskets made of expanded polyethene (PE).

Based on the knowledge we have gained in recent years and the perceived needs of the market we decided to invest in a line for the production of silicone-coated films in 2019.

For this purpose, a new production hall was built in OIC Hrpelje.

The main goal of the company is to perform the activity with quality and fast response time, to maintain reliable deliveries to our clients and to build long-term partnerships with our suppliers and clients.

We have state-of-the-art technological equipment that will constantly be renewed and improved, and consequently a wide range of silicone release liners.

Our team is professional, highly motivated and market-oriented from the very beginning. We build our efficiency on transferring knowledge to all the employees in the company.

Many activities have been carried out in the field of optimization, quality control and environmental care, with which we intend to successfully influence the growth of customer satisfaction.  Therefore, we are very proud to we work according to ISO 9001 and ISO 14001 standards

From the very beginning, the company PROEKO PLASTIKA d.o.o. gained an important share of customers in the European market.


This year we obtained both ISO certificates for the silicone coating plant in Kozina.
