Testliner is a recycled linerboard used as the outer and inner facings of corrugated board. It plays a central role in the strength, durability, and performance of corrugated packaging.

Supplied in a range of grades and grammages, testliner provides the burst strength, compression resistance, and surface properties required for producing reliable corrugated boxes. The quality and consistency of the testliner directly influence the structural performance of the finished board and box

Manufactured for consistent thickness and strength, testliner is designed to run smoothly on corrugating machines, supporting stable production and reducing variability during converting. Its surface characteristics also allow for standard printing and branding requirements where needed.

Testliner is widely used in packaging applications where cost efficiency, structural performance, and availability are critical, including transport, storage, and general-purpose corrugated packaging.
