Elongation is a key property for several packaging applications. The relationship between shrinkage and elongation of paper was investigated over a wide range, in order to understand and develop high extensibility for paper. The same dimensional contraction brought about by shrinkage can be strained out in tensile testing. However, percentage-wise the elongation is greater than the shrinkage due to different reference points, and the difference increases strongly at higher shrinkage levels. Elongation of paper can be explained mainly by two factors: the shrinkage and the net elongation of paper.
