Abstract Wood-fiber-based packaging materials offer only limited formability in 3D, which is an obstacle to their usability for complex 3D shapes. Although the requirements of good differ different forming processes, paperboard with a high elongation capability processes often desirable. In this study, tray (fixed blank process) was succesfully increased by curlation treatment bleached birch kr...

This article describes the use of Gaussian Processes in model reduction techniques with application to inverse problems. Mainly, the work is focused on the proper construction of the model approximation, namely on training process based on minimal number of learning samples, by making use of automatic samples selection through computed standard deviation of model prediction. An example of appli...

Crease cracking of paperboard is important to control for the appearance and structural integrity packages. affected by creasing operation variables, as well physical properties paperboard. However, effects are not clearly known. The objectives this work were identify key material that affect crease clarify fiber composition starch. Laboratory sheets produced from bleached refined softwood hard...

The perspectives and attitudes of the companies of the forest products industry operating in the fields of solid wood products, pulp, paper and paperboard products, engineered wood products and furniture manufacturing in Turkey on the chain of custody certification system and certified forest products were investigated. Within this scope, face-to-face interviews were conducted with the managers...

Starch-based adhesives play a relevant role in paperboard production and are becoming more and more interesting, for different uses, because they are based on renewable biopolymers. Starch modifications or additive addition are becoming frequent to obtain the macroscopic properties desired for specific uses. In this paper the effects of the addition of four different tannins on a typical adhesi...
