It is our double-layered liner paper produced by adding secondary fiber on secondary fiber. It is widely used today, where recycling is of great importance. Testliner, which is produced entirely from waste paper, is the most preferred surface paper, which is easy to process and is highly resistant to printing in box production. In its production, starch and resin are added. From time to time, paint can be used to give color. Since it is a surface paper, the burst value is important.
