Paper Consists of a layer of sodden strands of cellulose mash which is derived from wood, clothes or grasses this material is let to dry so as to attain corrugated sheets which further have a wide application in the packaging industry. It is a flexible material which have various applications i.e composing, printing, bundling, enriching, and numerous modern and development measures.

As this paper consists of various materials from various parts of the world maintain the quality and durability becomes utmost important for the manufactures. It is crucial to test the bursting strength of paper in this case. Hence testronix bursting strength is proven to be the best solution to test the bursting strength of packaging material and is the most reliable and trustworthy brand in the industry.

Testronix bursting strength tester is used for measuring the bursting strength of paper accurately. Units for the same is Kg/cm2, and is called bursting strength. The instrument can be utilized to precisely decide the bursting strength of paper, creased cardboard, container box, card board, calfskin, fabric or engineered cowhides. Burst Factor (BF) and Burst Index (BI) can be effectively determined if GSM of the example is known.

Burst Factor = Bursting Strength (g/cm2) ÷ gsm (g/m2)
Burst Index = Bursting Strength (KPa) ÷ gsm (g/m2)


Item Features

  • Push Button Operation

  • Peak Hold facility for keeping maximum value of test result in memory
  • Memory to hold up to 9 test reading
  • Highly accurate test results under multidirectional Force
  • Digital screen for accurate results
  • Strong Gripping clamps
  • Grooved structure of Test Specimen Holder to provide firm grip
  • Firm grip of specimen if the operating wheel is tightened uniformly

Testronix Bursting strength calculates the force required to rupture the material under testing. Bursting strength of test specimen is expressed in terms of Kg/cm². It is measured by giving hydraulic pressure through a rubber diaphragm on the test specimen.
