Paperboard is thicker than paper, easy to cut and form, lightweight, and most important a strong material demanded by most of the packaging industries. Presto offers the high quality and reliable Paperboards Bursting Strength Tester to measure the ability of paperboard boxes to resist the external compression loads during transportation and storage. The bursting strength enables the manufacturers to know the actual quality of material before manufacturing and aids in producing the good quality of paperboard boxes.
Paperboard bursting strength tester enables to test the strength of the paperboard boxes as the compressive pressure during the transportation can cause the boxes to burst. Bursting strength of paperboards must be determined to ensure that paperboard will able to resist the pressure and load during storage or transit.
The machine has lower and upper clamps in which specimen or sample of paperboard is placed and then tightened using the geared handle provided. The handle is also used (moving up and down) to apply the increasing pressure (hydraulic) on the left side of tester causing the diaphragm to expand till the specimen deformed or ruptured. Reading of pressure is the bursting strength that be can be read on the digital display provided. The measurement unit paperboard is given in kg/cm2. Presto offers the highly competent B S testers available in five models. The machine is economical and simple to use.
