FDT-01 Polypropylene Film Drop Dart Tester

Measuring the impact resistance of polypropylene film using the falling dart impact method


Polypropylene film has high strength and abrasion resistance, and is lightweight and easy to carry, so polypropylene film is commonly used to package food, pharmaceuticals, cosmetics, daily necessities and other commodities and to manufacture various types of plastic bags. By measuring the impact resistance of polypropylene films, it is possible to assess their ability to maintain their integrity when subjected to external impact forces. Falling dart impact test is a traditional way to determine the energy that causes a polypropylene film to fail under specified conditions of impact of a free-falling dart.


FDT-01 Falling Dart Impact Tester is used to measure he resistance performance of polypropylene film with less than 1mm thickness. This test indicates polypropylene film ability to resist external force.

Technical Features

FDT-01 Falling Dart Impact Tester is a PLC controlled unit (industrial level stable) and HMI touch screen operated. Every part of the dart assembly and releasing mechanism are made strictly to standard.

By the embedded test program, user just needs to perform test and increase or reduce the weights according to the set parameters. Then after a number of Fail/Non-Fail tests, the system automatically gives impact result, which is without being manually calculated again.

  1. PLC control and touch screen operation
  2. Two tests methods of A and B (B optional)
  3. Test results of both gram and Joule display
  4. Electromagnetic suspension and automatic falling
  5. Sample pneumatic clamping
  6. Observation light for checking sample status when clamping
  7. Manual and foot switch equipped for safe and easy operation
  8. Dot matrix type micro-printer for data export
  9. Professional software (optional)
