Coreboard for Cores & Paper Corner Protectors

We produce exclusively Coreboard, with specifications tailored to your machine.

Coreboard for Paper Cores & Tubes

Coreboard for Paper Cores & Tubes

Specially engineered board for producing winding cores (high-load & standard industrial cores).

  • High Interlayer Bond Strength (Delamination / Scott Bond)

    Resists shear forces during high-speed winding, preventing the board from “delaminating” on your machine.

  • Crush Resistance

    Enhances the strength of the finished paper core under vertical and horizontal loads (Radial & Side Crush).

  • Controlled Moisture (% Moisture)

    Consistent moisture content for fast, uniform glue absorption, without warping during drying.

Coreboard for Paper Corner Protectors / Edgeboards

Coreboard for Paper Corner Protectors / Edgeboards

Specially designed board for producing and forming paper pallet corner protectors.

  • Bending Stiffness

    Ensures the finished paper corner protector holds its 90° angle under high strapping tension.

  • Caliper Control

    Uniform thickness for consistent compression and pressing when forming multiple layers.

Slitting & Supply Standards

01

Master Rolls & Slit Rolls

Slitting available down to narrow widths from 70 mm up to full rolls, matched to your machine's specifications.

02

Clean Edge Cut

Dust-free edge cutting, protecting the rollers and blades on your own production line.

03

Roll Tension & Diameter

Consistent tension control and a choice of 1000–1300 mm outer diameter to maximize your machines' continuous run time.

Technical Testing & Quality Certification (Quality Control)

Every batch of Coreboard leaving the GSM Papermill factory in Kilkis undergoes strict laboratory testing:
