Summary
BEGHIN-SAY has worked on a new process of impregnation of corrugated board by total dipping in a solution of resin in a hot organic solvent with solvent recycling. This cyclic process takes place after all usual manufacturing steps including printing and gluing.
Based on French Patent Nr 2 294 763, the process was widely tested and improved, the improvements giving a new process with enough industrial reproducability. The specific properties of impregnated board were summarized; stacking strength is for instance improved after impregnation by 80% in wet atmosphere.
Results of Marketing and engineering studies, made at the same time as the present research, bring BEGHIN-SAY to drop impregnation as a research subject.
