  • Electronic Bursting Tester

    Product introduction

    This instrument is an international general (Mullen)-type apparatus, widely applied to packaging materials, mainly for the determination of Single and multi-layer cardboard and corrugated cardboard can also be used for silk, cotton and other non-paper materials, the bursting strength test. To put material only then automatically detect, automatic testing, automatic hydraulic recoil and automatic calculations, store test data, print instrument with digital display and can automatically print test results and data processing.

    What is burst tester?

    Burst testing is conducted by introducing air (or other gas) into the package at a controlled rate, maintaining the internal pressure for a specific length of time, and inspecting for material failure. The entire package is subjected to uniform stress and failure generally reveals the weakest point.


    How do you test bursting strength?

    Summary of Test Method

    A specimen is clamped over an expandable diaphragm. The diaphragm is expanded by fluid pressure to the point of specimen rupture. The difference between the total pressure required to rupture the specimen and the pressure required to inflate the diaphragm is reported as the bursting strength.
