Characteristic Test(Mechanical Characteristic)

Universal tension test

The maximum load and elongation of a rectangular test piece in a given shape (15 mm in width) when a tensional force is applied to it until it breaks are investigated. These are measured using a universal tension tester and are one of the basic physical properties of sheets.

Burst strength test

The burst strength of sheets is investigated. The pressure required to burst a sheet when vertical pressure is applied to a given area of the sheet surface with the periphery secured is measured.

Tearing strength test

The resistance generated when a sheet is torn is investigated. We measure this force using an Elmendorf tearing tester.

Folding endurance test

The durability of a sheet when bent repeatedly in the tension state is investigated. We measure this durability using an MIT-type fold tester.

Folding endurance test

Stiffness test

The flexing life of paperboard is investigated. Soft paper, such as tissue, cannot be tested. We use a Gurley-type stiffness tester for measurements.

Ring crush test

In this test, the buckling strength of a sheet is investigated. The compressive strength of the sheet used for the base paper for corrugated board and honeycomb application is measured using a ring rush tester.
