Fluting
The middle layer of corrugated board. Produced in the 70–140 g/m² range.
A mill producing fluting, testliner and bag paper from 100% waste paper. Installed capacity 300,000 tonnes/year, grammage range 70–140 g/m². Continuous production began on 13 November 2025.

The main machine of the mill, built on a 100,000 m² allocated site in Konya Ereğli OIZ, is Stora Enso’s former PM3 line from Finland: 6.6 metres wide with a line length of 180 metres. Continuous production started on 13 November 2025; the first paper sale was made on the last day of 2025. Planned production for 2027 is 270,000 tonnes.
Barem Ambalaj's Ereğli Paper Mill is one of Türkiye's integrated mills producing fluting, testliner and bag paper from 100% recycled waste paper: 300,000 tonnes a year of installed capacity, a 70–140 g/m² grammage range, a 6.6-metre-wide paper machine and RCT–CMT records for every reel via PaperLab. Part of the paper goes into Barem's own litho-laminated box production; the rest is sold to corrugated board and paper sack manufacturers in Türkiye and export markets.

To date, USD 41 million has been invested in the 32 MWe cogeneration plant that will supply the paper mill’s electricity and steam. Full-capacity commissioning is expected by the end of 2026. The 3,607 kWp rooftop solar on the three packaging plants has been generating since 2022.


The 7,000 m³ treatment plant in Ereğli was built to recover process water.
Every reel produced is scanned at thousands of points by PaperLab sensors; critical values such as RCT, CMT and moisture are recorded digitally during production.

Fluting with consistent crush strength (RCT, CMT) and moisture stability for corrugators; testliner with high burst strength for the box surface. Reel-level PaperLab records and reliable lead times.
100% recycled sack paper with high tear and tensile strength for cement, flour, sugar, feed and chemical sacks; 70–140 g/m² on the same line.
The corrugated board of the litho-laminated boxes made at our offset packaging plants in Tire, Gaziantep and Karaman is produced from Ereğli paper: single-source traceability from paper to box.
Reel width, grammage and quantity are set per order; the technical data sheet is shared together with the sample reel.

Fluting is the wavy (corrugated) middle layer of corrugated board. It determines the crush and stacking strength of the box and is measured by RCT (ring crush) and CMT (corrugated crush) values. In Ereğli we produce it from 100% recycled waste paper in the 70–140 g/m² range.
Testliner is the recycled liner paper that forms the outer and inner faces of corrugated board. It provides the print surface and burst strength. In Ereğli we produce 70–140 g/m² testliner; grammages below 100 g/m² are preferred for lightweight boxes.
Bag paper is a high tear- and tensile-strength paper used for the paper sacks of bulk products such as cement, flour, sugar, feed and chemicals. In Ereğli we produce 70–140 g/m² bag paper on the same line.
