Packaging Testing Equipment is intended to determine the resistance of corrugated board, solid board or corrugated cases to various compression and burst in given conditions. Different testing machines and auxiliary devices are used to perform the bursting strength tests, ring crush tests, edge crush tests, flat crush tests, pin adhesion tests, puncture strength tests, compression tests, damp-proof tests, etc. These tests are indispensable to judge the properties of packaging boxes. Paper test items mainly include the tests for thickness, whiteness, smoothness, breaking elongation, bursting strength, folding endurance, stiffness, tearability, etc.
