Measure Bursting Strength of Paperboard to Assure Quality

A property of paperboard that is used to pack various products can be used to test the resistance of rupture, referred to as the hydrostatic pressure required to burst a paperboard sample, applied uniformly across its side. Bursting strength is a function performed in the papermaking process.

Bursting strength is evaluated using a rubber diaphragm which is expanded against the paper sample. The bursting test can be known by another name i.e. Mullen test. Various properties to test in the paper board for high-quality control.

A standardised and precise paperboard testing instruments should be used. Bursting strength of paperboard is important in the formation of strong structure. Bursting strength is the resistance levels displayed by a material under bursting or rupture forces. It is difficult to choose from a variety of Bursting Strength Tester for carton box in Market. There are few machines designed as per the global standards and have features for Paperboard testing.

Bursting Strength Tester Digital by Pacorr is popular among paperboard manufacturers. The machine is designed by a team of proficient engineers and standardization experts. The equipment adheres to ASTM D 3786-01, ASTM D 3786 – 80A, and ISO 1060 PART-1 1987. A chip based digitally controlled system to ensure better consistency. Bright and Clear Vision screens for a test read out. The display has a LED source for more clear vision. The screen on the left shows sample burst value and screen on the right shows the machine’s pressure range. Bursting strength of paperboard is measured using a base pressure method. From upwards the manual clamping applies pressure and from the base, a flexible and inflating diaphragm.

In the display section, the user has feather touch buttons for parameter setting. There is a facility of the tare and peak hold value. Inbuilt Calibration lock can be availed. Using the same one can first calibrate and then lock the machine on that mode. Burst Strength Tester has a single clamping head for testing multiple samples, no need of continues head changing hassle. The rotating head for clamping the sample tight is manual. The base plate on which the sample is placed has a circular grooved structure. Bursting strength of paperboard needs a standard test with zero error, the grooved structure assures that the sample does not have a slipping tendency during the bursting test. The main switch is there for getting on with the machine and a push button for initiating the test cycle after sample clamping and setting test parameter.
